FAQ

Frequently Asked Questions

(Q) What are your shipping and return policies?

(A) Please visit our policies page.

(Q) Is your new seal FAA approved for my airplane?

(A) The new seal has been designed specifically for your airplane and is FAA approved. It is a direct replacement for your old seal.

(Q) I heard that you sell a seal that installs on the fuselage. Can I get a new seal that installs on the door or window?

(A) Yes! In response to the many requests from owners, in 2007 we designed a revolutionary new seal that installs on the door. So now you have a choice of either a fuselage or door installed seal for most aircraft.

(Q) What makes your new seal better than what is currently installed on the airplane?

(A) Unlike off-the-shelf rubber seals that really don’t work well, our special tooling molds the new seal to the exact contour and fit of the aircraft door ensuring a perfect and airtight seal.

(Q) Does an A&P Mechanic have to do the installation or can I install your new seal?

(A) Since the new seal is FAA-PMA approved as a direct replacement for your old seal and comes with an FAA-PMA Tag, you as the owner can install the seal with a log book entry.

(Q) I just replaced the door seal with an OEM door seal ordered from the factory. I can hardly close the door and it still leaks. Will your door seal correct this problem?

(A) Yes it will! Because our new seal was specifically designed for your airplane, it will fit the contour of the door, as well as the door sealing surface, providing an airtight and leak-proof seal.

(Q) The door seal on my plane is a quarter-round rubber seal that doesn’t seal perfectly all the way around the door. How is your seal better?

(A) The quarter-round seal is just common sponge rubber that is hard to compress. The older it gets, the more it resists compression. Our seal is a special compound that was specifically formulated and molded to conform to the door as well as the contour of the fuselage and will compress forming a perfect leak-proof and airtight seal.

(Q) The rear door on my piper aircraft is fiberglass and doesn’t fit well. Will your new seal compensate for a badly fitting door?

(A) In most cases, the new seal will compensate for a badly fitting door. There are several causes for doors not sealing well. First, molded fiberglass loses some of its shape as it ages due to it’s chemical nature. Second, over time, quarter-round seals lose their ability to make good contact around the entire door and fuselage. Third, eyebolts and clevis pins wear out, but never get replaced, which allows the door to sag and prevents a proper fit and latch. Contact us about your door. We’ll be glad to provide instructions for adjusting the doors.

(Q) The door seems harder to close after installing the new seal. Is this normal?

(A) This is very normal. Depending on the temperature, the new seal may take a day or two to compress and conform to the different dimensions around the door opening. After the new seal has conformed to the door opening, it will provide a perfect seal and close easily.

Q) Is there any maintenance required after installing your seals?

(A) Yes, the seal will need to be cleaned and a light film of silicone grease applied each year to keep the seal from drying out. These instructions for continued airworthiness are provided in each seal package.
