I did not use this for its intended purpose on an aircraft. Instead I used it as heat tubes on my Volkswagen. It not only looks better than the original version but it is so much easier to work with. Love it!

Top quality ducting, Great price, incredibly fast processing of orders every time. I often use this for classic car intake ducting, or using SCAT heat ducting in air cooled Porsche.

Easy to work with and works great for heat ducting for my Porsche 911

Q: Hello, If I purchase 3 foot of CAT Ducting will it come in 3 individual one foots or will it come in one 3 foot length? Thanks Adrian

An order for 3 feet will be delivered at 3 continuous feet, unless noted in special instructions to cut into 3, 1 foot lengths.

Q: Is the dash number of the CAT hose in feet? In other words, is a -24, 24 feet long?

No, the dash number is the extension used after CAT to complete the industry standard part number. For example, the part number would be CAT-2A, CAT-3, etc. All CAT ducting is priced and sold per foot, so to get 24 feet, order quantity 24.

Q: What is the weight per foot for the 2" CAT Ducting, part # 05-29808?

The weight per foot would be .14lbs.

Q: Is part # 05-29808 black not orange? (I want black)

Yes, 05-29808 is black.

Q: Is the material thickness of the red silicone rubber the same for SCAT4, SCAT8 and SCAT9?

Yes, the only difference is the diameter of the ducting. The material is the same.

Q: My Cessna IPC shows a p/n s1053e8t12.00 (the 12.00 = 12long). Does this number cross with your p/n and tell you the hose diameter?

No, this part number does not cross over.
