Silicone Hose Coupler, 3 1/4 inch ID, 4 inch Length

Our silicone hose is built for endurance and performance in custom coolant and intake plumbing applications. Each hose is hand-crafted from multiple layers of silicone rubber with polyester reinforcing fabric between the layers. The silicone rubber remains flexible and tough from -50° C to +180° C (-76° F to 356° F).

These 4 inch (102mm) long straight hoses have a 3 1/4" (83mm) ID with a smooth, shiny "wipe-down" finish. The 4-ply reinforcement results in a working pressure rating in excess of 19 psi (78 psi burst pressure) and a 5.5mm wall thickness (94mm / 3 11/16" OD). Use our Lined Hose Clamps (Part No. 3613-4.00) to clamp over a 3 1/4" OD tube.

Note: This hose is NOT formulated for use in oil or fuel plumbing applications. It will survive occasional spills and oil leaks, but it will not stand up to continuous exposure to petroleum.
