What our customers are saying:

"Just wanted to say thank you for realizing I ordered two items on separate occasions over the weekend and you combined shipping and refunded the difference. I used to run my own business for years and it's little things like that that make a huge difference. Really shows you're paying attention to what's going on and not just chucking things in a box and sending them on the way. I may not be the most prolific customer but you have one for life."

Silicone Coolant Hoses by Shape

This hose is built for endurance and performance in custom coolant plumbing applications. Silicone rubber with 3-ply textile reinforcement (4-ply on 51mm and larger sizes) makes this hose tough, reliable, and flexible to temperatures from -60°C to +180°C.

Choose bright Blue, Black, or Red. Each color has a smooth, shiny "wipe-down" finish. Use with our Aluminum Splicing Nipples (Part No. HJ##) and Lined Hose Clamps (Part No. 3613-Size) to construct the exact shapes and lengths you need.

We also offer many Silicone Turbo Intake Hoses and Elbows in larger sizes up to 6" ID!
