Vibrant Performance HD Pinless Clamp Assemblies

Traditionally, silicone couplers were the go-to solution for connecting charge tubing. With the advent of much higher horsepower turbo applications producing high amounts of boost pressure meant a more robust solution was needed, and the Vibrant HD Clamp was born. Making the best even better, there is a new generation of modular billet aluminum clamp systems—Vibrant HD Pinless clamp assemblies. Vibrant HD Pinless clamps are single units with an integrated clasp mechanism and a safety lock push-button, replacing the old quick-release pin. This clasp mechanism is very easy to use and delivers a significantly more secure connection, while the safety lock, which is always set in the locked position, provides an extra level of security to ensure the clamp never pops open unintentionally. Not only do you get a more robust connection, but you never again need to worry about a pin getting lost or malfunctioning due to debris buildup. As a bonus, the Pinless HD clamps provide the installer with positive feedback and an audible click when properly closed. The design is completely backwards compatible with any existing HD system and offer the strongest quick-release connection, while allowing a degree of flexibility to allow for engine movement. Vibrant HD clamp assemblies feature precision CNC-machined 6061 billet aluminum clamp with hard anodized finish, a pair of weld ferrules with specialized O-rings, and hard anodized union sleeve. They are available in a variety of sizes to suit any custom charge system. Choose the security, strength, and style of Pinless clamp assemblies for your high performance application.
