Hargett Precesion 2 Piece Couplers


HPP's QDC style 2 piece couplers provide significantly improved ease of use when connecting and disconnecting liquid hose and intake/intercooler tube applications. They provide the same high-quality connection as premium coupler systems at approximately 60% less cost, and deliver a price/value advantage over traditional hose-and-clamp coupling methods!


The QDC is a coupling system that includes interlocking aluminum couplers that are fastened by a tensioner clamp, with internal double O-ring seals that provide ultimate sealing capabilities. The couplers are precision CNC-machined from lightweight 6061 T-6 aluminum, making them easy to weld to existing plumbing hardware for air or liquid connections.


Racers know that every second counts, especially in the pits. Hargett Precision's QDCs simplify the ability to connect and disconnect critical air and fluid plumbing connections over traditional rubber/silicone coupler and steel clamp connections, which reduces the time required to access or change critical engine components. Connection and disconnection with the QDC can be performed with one hand and no tools are required, making them ideal for virtually all forms of racing.


Street performance enthusiasts will appreciate the QDC's ease of use, and the product's high-quality finish will complement and enhance the look of any engine compartment. All users will recognize the value of Hargett Precision's QDCs over traditional silicone/stainless-steel coupling systems the first time they are used.
