Bite-Type (24 degree )Compression Sleeve Connection System for Pressures to 15,000 psi.
Safe, Reliable, Cost Effective
Parker Autoclave Engineers , the recognized world leading design and manufacturer of high pressure process instrumentation equipment to 150,000 psi (10342 bar) has engineered an advanced single bite-type compression sleeve fitting system called QSS (Quick Set System). Available for use with Cold Worked 1/8 hard Medium Pressure tubing sizes 1/4" through 1" O.D. and made from 316 SS, 2507® Super Duplex or Inconel 625™, this amazing tube and fitting system operates in all sizes - within these three material options - to 15,000 psi (1034 bar).
The single bite-type compression sleeve creates a uniform mechanical sealing surface not affected by surface scratches that can cause issues with more traditional dual ferrule compression type fittings while creating an “edge” that prevents tube extraction at these very high pressures. This vibration resistant design is capable of working in temperatures from -100º to 600ºF (-73º to 316ºC). The single piece design reduces the risk of lost ferrules, ferrule mix-up, vibration sensitivity, and multiple sealing points common to two-ferrule system.

In certain applications, the QSS sleeve-type fitting system can be an advantage for your installation. With only a wrench and/or torque wrench for the smaller sizes and our hydraulic set tool for the 9/16" size and up, only minimal training or knowledge is needed to create safe, resettable, tube end connections, reducing installation man hours by as much as 50% or more as compared to MP Cone and Thread designs.
