Product Review

Squirrelly's line of silicone couplers feature 3 layers of polyester reinforcement and are suitable for applications with boost pressures up to 45psi. They also feature a temperature rating of 428°F for direct to turbocharger installations.  Don't be fooled by cheap '4-ply' couplers, sellers generally use it as a marketing term to mean quality which is often not the case.  Our '3-ply' meet rigorous standards and have been field tested time and time again.

Features:

Size: 4" to 3.5"

Material: 3-ply Polyester Reinforced

Temp: 428 Degrees F (220 C)

Includes 2 T-bolt clamps
