Collection: Straight Silicone Hose & Couplers - Proflow
Browse Proflow straight silicone hose and couplers for intake and intercooler pipe connections. Compare sizes and lengths, and check the individual product's specifications to suit your installation.
Choosing a Straight Silicone Coupler
- Internal diameter: Match the hose's internal diameter to the outside diameter of the connecting pipes.
- Length and clearance: Check the overall length, pipe engagement and space available for clamps.
- Application ratings: Confirm the product's working-pressure, temperature and fluid compatibility ratings before ordering. Do not use burst pressure as a working-pressure rating.
- Clamps and installation: Choose clamps to suit the installed hose diameter and follow the manufacturer's fitting instructions.
