Silicone Couplers Turbo Hose REDUCERS - 3-inch Length (Choose Transition Diameters)
These are Vibrant 4-ply reinfored silicone connectors for intake and intercooler applications. Available in a range of diameters in 3" lengths, you can get whatever size you need. Because of their reinforced construction, they are made to withstand high boost applications and underhood temperatures without swelling and bursting like cheap rubber couplers. Reducers allow you to connect two different sized pipes without having to "clamp down" on one pipe to make a straight coupler work - this almost always results in the pipes coming uncoupled. Available in Gloss Black, Gloss Blue, and Gloss Red.
Select the coupler IDs (inside diameters) and color from the options menu below. These are single reducing/transition couplers 3 inches long.
