  • Easy to replace review by Jeri
    5 5 Easy to replace

    I was able to take the old panel out and replace with the new panel quite easily. The material between the clear panels is what gave out so until that material is beefed up I think we will be replacing this again. First one lasted a year.

    It keeps the wind out but the dogs have access. Now if they’ll just stop trying to go through two or three at a time!

    5 5 Terrific Service!

    So excited to get the replacement door so quickly - ours is about 5 yrs old and the bottom section broke off. Gunner makes great use of the door, sometimes hitting it at a full run. It was easy to install, and fit perfectly. Thank you for shipping it the next day, you being in SoCal help it arrive right away.

  • draft stopper replacement flap review by gloribe
    5 4 draft stopper replacement flap

    I'm satisfied with this product and its easy to install. However, I wish I could have purchased just the rubber part between the "windows" since that is the only thing that broke. I've kept my old one in order to use the good parts if I need them again.

  • Flap does it's job review by VALERIE
    5 5 Flap does it's job

    Unlike the plastic, 1 piece flaps that don't shut securely this one does; therefore saving on your heating and cooling. I have 3 large dogs and 2 cats that use it all day every day and it really holds up to the test. Only down fall is that I have not been able to locate it with tint to keep the sun from shining it the den.

  • Waste of money review by Higgs
    5 1 Waste of money

    I just wasted $70 on this Ideal Pet Premium Draft Stopper piece of junk. There is a HUGE gap that is left in this pet door after our pet walks in or out. Now the air conditioning or heating is going to float right out through that door. How on earth they can call it a "premium draft stopper" is beyond me. I've had much cheaper doors in the past but the flap would close all the way. This flap just dangles open leaving gaps for wind, air, rain and bugs. Now that I have installed it, I can't return it. To add insult to injury the patio door was brand new, too. So now I have a new patio door and a piece of junk pet door. Do not buy this.

    5 5 excellent dor

    I bought the original 5 years ago and they seal good and lasted a long time. I have two dogs and a large yard so they were used a lot. I live in the NE so winters are long and cold and they sealed better than any other door I tried in the past. I highly recommend this product and the fact you can buy a replacement is even better

  • It was so easy to install ..... review by MaW
    5 5 It was so easy to install .....

    Instead of replacing the entire door, replacing the flap was a snap!!! Although it would have been nice to be able to replace just the rubber strips, this was still a perfect solution to a simple/common problem.

  • Fantastic, The Dogs Love It review by Linda
    5 5 Fantastic, The Dogs Love It

    The replacement door fits perfectly and has an excellent seal all around. The original door was smoke colored. The replacement door is clear, which makes it easier for the dogs to check things out in either direction before using it. Rosie especially likes it because she can simply sit and watch the squirrels from inside and pounce when the time is right!

  • Door review by Robert
    5 4 Door

    I did feel that having to buy the whole pet door when all I wanted was the rubber strip was excessive and a fault in the design , however as I was forced to purchase the whole door it was easy to fit and well made.

    5 5 So happy I can replace just flap1

    Great that I can replace just flap! It isn't easy and pieces went flying but we are back in business. The end-caps for the rod need to be replaced as they are getting brittle. Hope I can get it hem without buying a whole new door

  • love the door review by Ginger
    5 5 love the door

    To be honest, I have not received my replacement flaps yet. Not your fault. I have it mailed in the states and then wait for a visit by my son or daughter to bring me the stuff mailed to me back in the states. I live in Costa Rica and to ship here is terribly expensive. However, this being said, I do know about the flap system and I really like. The flaps never needed replacing when I lived in NV. Unfortunately, those rubber gaskets don't do well here, where the humidity and heat destroy them. I've only had 1 1/2 years of usage with this door and it needs the new flaps. We have jerryrigged the door flaps together a few times now while waiting for the replacements. So, to make things more affordable, I ordered 2 and that should keep me for about 3 years, and hopefully more. I do find the cost of the flaps to be extremely expensive, but that's life.

  • Great fit! review by Lowell
    5 5 Great fit!

    I have had my UltrFlex dog door for over 15 years. I was delighted to find a replacement flap for my door. The old one was leaking air because the old gaskets had got brittle and broke off. It was an easy install and it fits great! It is as airtight as the day it was new 15 years ago.

  • Good replacement but only needed flap gaskets - found them review by Tbird56
    5 4 Good replacement but only needed flap gaskets - found them

    Bought and replaced flaps but only flap gaskets were worn. This was clear while original was smoky so looked at Ideal Pet and found flap gaskets. Long term, both work but will need gaskets more often. Will keep this for later when actual plastic door flap needs replacement.

  • Nice idea but you Gotta keep replacing them review by Lotsadogs
    5 3 Nice idea but you Gotta keep replacing them

    We purchased the door with this flap because we live in a high-altitude environment with lots of wind and cold. It sort of works, but is thick and heavy for the dogs, doesn't really keep out the wind (I think because the frame with magnetic breaks down) and it tears apart after repeated times of heads bashing through it. We have to replace it every 6 months or so.

  • Only issue is the rubber flap hinges and the seal at top and bottom of the flaps, wish we could get enough to maintain our 24 units a 8 for spares. Sun seems to make them dry out and crack, causing failure. review by Bob
    5 4 Only issue is the rubber flap hinges and the seal at top and bottom of the flaps, wish we could get enough to maintain our 24 units a 8 for spares. Sun seems to make them dry out and crack, causing failure.

    We converted to this flap a year ago and are pleased with the performance and durability of the plastic flaps. Currently have 32 with only 8 to rebuild. Dogs seem to adapt quicker to this unit and help control costs in our kennels.

    5 4 Excellent fit

    I also wish the flaps were easier to replace. We have 3 labls and they do not slow down coming in or out, sometimes more than one try to use it at the same time! But so far I haven't come across anything better than these.

  • Pet door review by DT
    5 3 Pet door

    The product came quickly and installed easily, I agree with a lot of the comments from others in reference to this door. The dogs put it through some abuse and it will fall apart again. If we could get replacement parts, like rubber strips, sections that get broke etc.. it would be more cost effective. Otherwise it's a good pet door

  • Wish We could Get the Plastic Connection Strip review by Chuck
    5 3 Wish We could Get the Plastic Connection Strip

    Although the replacement door panel is easy to replace it is expensive and will fail with a dog which loves to burst through the door. The repair to the door panel can also be done by replacing the strip between the door sections, but this not available through PetDoors.

    I found this door replacement easy to change from old to new. The last time we replaced this was with door replacement 9 years ago.
    When it is time to replace it again we will reorder with this company - good service and fast delivery.

    I would recommend to dog owners .

  • Great design but not durable review by Cheshire
    5 3 Great design but not durable

    This is a great pet door and provides easy access. It is also fairly energy efficient being double walled.

    However the flexible hinge that joins each piece to the next is not durable and will wear out after about 18 months so you might as well go ahead and by replacements before you need it.

  • Good product review by Kristin
    5 4 Good product

    I use mine for a cat door and my first one lasted 6 years. It keeps the cats mobile and the raccoons haven't figured it out yet. It does let the draft in through all kinds of air holes in the frame and the door panel; I'm sure my electric bill would be drastically cut if I took it out. Bees also get in through the gap now and then. Replacement is super easy.

  • stupid dogs review by Joseph
    5 2 stupid dogs

    I go through 3 of these a year. I have 2 Australian shepherds that hit them so hard they either tear the rubber between the panels or they crack the acrylic panel and the screws fall out. I have the insert door for a vinyl patio door. I wish they made a simple all PVC door replacement for this 3 panel door. It would hold up better to the boys crashing through it to get at the ducks that land in our pool......

  • very good just not like the orignal review by shirley
    5 4 very good just not like the orignal

    This replacement door is very good . However it doesn't fit as closely as the original door did. It seems to have a fraction of an inch that keeps it from closing all of the time completely. However the fact that we could even replace it to begin with is a bonus. It is heavy weight but not so heavy that our dog has trouble with it. The quick shipping and the reasonable price has made us forever customers.

Replacing Ideal Draft Stopper or Ultra Flex Flaps

Click below to expand:

It is compatible with the Ideal "Ultra-Flex / Draft Stopper" door, and VIP 150 Panel.

They're the same product - just different names.

The ultra flex door and the Airseal are the same.

Yes - that is an ultra flex/draft stopper door in the panel.

No, the ideal ultraflex draft stopper only comes with the flap. We don't carry any other draft stopper ideal replacement part.

Unfortunately we only sell the ultraflex replacement flaps. To get ultra flex flexible gasket material, or other ultraflex flap door parts please contact the manufacturer, Ideal Pet Products.

No, it will not attach to ANY other model.

The 3 rigid chew-proof flap segments are divided by a flexible gasket material to make the flap more flexible


Some storm doors with pet doors pre-installed did use this door, so as long as you are pretty sure you have the ultra flex it should work.

You can apply some sort of bitter deterrent on the hinges so that your dog will not continue to chew them off. (Make sure to do some research to ensure the deterrent is safe!)

This depends entirely on how active your pet is as well as your climate. Areas that are colder tend to turn the rubber connectors rigid and brittle, thus make it more susceptible to breaking. If you have a very active pet that uses the door a lot or goes through it with a large force you may also need to replace the connectors more often.

No this will not work any other Ideal model door.

It sounds like the Ideal replacement door flap you need is for the Ultra-Flex / Draft Stopper. It is a uniquely designed flap and you can verify the measurements to confirm it is the correct replacement flap.
