Product Description

This BOOST Products HD Flex connector kit is for builders who need a better way to separate and service a 3.5-inch aluminum pipe section than a conventional fixed connection. The quick-release closure opens and closes in seconds without tools, making it easier to remove charge piping, an intake section, or a water-line assembly when access is needed.

Its dual O-ring seal is designed for pressure applications up to 10 bar, while the flexible connector design accommodates normal component movement and vibration. The matte black finish keeps the connection looking clean in a custom engine bay.

Fabrication Notes

This kit is intended for 3.5-inch / 89 mm aluminum piping. Confirm your pipe outside diameter and plan the connector location before beginning fabrication. It is not a standard slip-on silicone coupler or a clamp that simply installs over an existing hose.
