ISR Performance - Universal Silicone Coupler - 2.25" Straight

The ISR Performance Universal Silicone Coupler is a straight coupler in 2.25-inch diameter. Built from 4-ply reinforced silicone for extreme temperature and pressure environments, it's a direct fit for any custom intercooler piping, intake, or charge pipe application using 2.25-inch tubing.

What It Does

Silicone couplers connect two sections of piping in custom intercooler, intake, or boost piping setups. Straight couplers join two equal-diameter pipes, which is the most common application in intercooler plumbing, intake routing, and charge pipe builds. The 4-ply silicone construction handles the heat and boost pressure that lower-quality couplers fail under.
