PPE 1.75" ID x 2.75" Performance Silicone Coupler (Universal)

This is a PPE performance silicone coupler, 1.75" inside diameter and 2.75" long, for joining tubing on custom intake and charge-air setups. It’s a building block for clean, boost-ready plumbing.

The multi-ply silicone construction handles the heat and pressure of a boosted engine bay and keeps its shape instead of ballooning under load. Its short length makes it perfect for tight connections between two hard pipes of the same size.

Fitment is universal, so it suits any build that needs to join 1.75" tubing – intake tracts, breather plumbing, or small charge-air sections. It’s the kind of part fabricators keep on hand.

Use a proper lined or T-bolt clamp (sold separately) at each end and confirm your tube outside diameter matches before ordering. The coupler carries PPE’s 1-year limited warranty.
