HPS HTSC-400-BLK Silicone High Temperature 4-Ply Reinforced Straight Coupler Hose, 65 PSI Maximum Pressure, 3 Length, 4 ID, Black

Great product!

This is not a coupler. Its the exact same size as 4 other pieces. So it dont work with other 4 parts.

Excellent hose piece. Using on performance watercraft exhaust

Works good only thing is not the size I needed

satisfied

Great product

It fits 4in aluminum intake pipe. It is very well made and should handle boost just fine.

Used this on my LLY Duramax to replace my 4 rubber plumbing coupler on my LBZ turbo mouthpiece. Used the hose clamps off that and it gives me peice of mind with this silicone peice that it can stand up to the engine heat without cracks. I must have to have it tighter to the air box tho you can hear it rattle against the hood when I start the truck.

Is a great product fast shipping.

great quality product. Very minimal flex when connected to the intake pipe and my bw s366 turbo inlet.
