🔥 Design Engineering Fire Sleeve and Tape Kit: Ultimate Heat Protection for Wires, Hoses & More - 1" x 3' Review

Ideal for -6AN hoses. Had to remove AN fittings to put it on. It can be split in half for installation, but this will only destroy the integrity of the hose cuff.

I bought this to fit a 5/8 hose and it fits perfectly to begin with so yes the 3/4 hose fits fine. I would still use ties depending on what you do. The only downside is that it's a bit pricey for something so small.

This is Amazing! It has high strength and is suitable for the working ends of some prefabricated stainless steel oil pipes. Be sure to seal the opening of the cuff as the inside of the cuff is quite fibrous. Overall I'm very happy to know that the pipes running next to the exhaust are protected.

I have an old Jeep V8 and added the headers. The underhood temp got a lot warmer and I decided to mitigate the shortened spark plug wire life with a .625" DEI socket. wire and put back. This bushing is enough for four cylinders, so the V8 needs two bushings.

I used this fire hose to protect some of the 5/8" heater hoses on my LSx RX7, and it was exactly what I needed.The product is well made and appears to be very durable.I have no doubts about the quality of DEI's products and I am confident that they will do the job and keep rubber hoses out of my manifolds The only thing that I think could be improved is to add some self-adhesive silicon tape as it will run out quickly if you have more than two ends to tape.

The product looked good but I didn't realize the tape wasn't in place until the grommet was installed. Don't take it off my 5/8 line. Revain doesn't have "just send me the missing part" so I can't return this without risking cutting the expensive fuel line I'm trying to protect. Beware of Prime too, it means nothing if you order a lot of items. It was a next day delivery and was delayed two days while waiting for other deliveries. They often do that to me. So I'm paying double for the product…

WORKS. Used this on my built EJ257 sti. I've had fuel pressure drop issues and never been able to figure it out in my life. I've tried everything in the book except adding an expansion tank. I wrapped 3/8ths of my custom fuel lines in this sleeve as my custom fuel lines were getting hot from my engine and manifolds. Once this was installed my fuel pressure was at a baseline of 45psi. The thing works and works well. My only issue is that the material is difficult to get in the right place…

It's expensive but worth it. I use this on my heater hoses, clutch line and my AC lines as they all run inches from my headers on my LS2 change machine. Does not melt, no foreign smells. Very happy with them. The friction tape you receive is for wrapping the ends of the sleeve. I have found that the friction band unwinds a bit over time. If I were to do it again (or ever remove the tubing again) I'd still use duct tape, but I'd try to find some large shrink tubing. So you can put the hose on…
