Our AlphaLoc couplers are an innovative 1/4 turn quick disconnect coupling. They are a spring loaded assembly with a fast thread and locking detent. No tools are needed for assembl y, more positive locking as pressure increases, flex to allow for engine movement, and O-ring sealing . We are very proud of the design and aesthetics. Available in 2", 2.5",3", 3.5" and 4"Note: When fabricating a system with AlphaLoc couplers make sure they will not be put in a mechanical load by movement of components. Also take care to not overheat and anneal the ferrules with the pins in them. We recommend welding about an inch and letting cool then repeat. If the ferrules are annealed the pins can elongate their holes and the couplers can leak or fail. Show more
