Gyrolok XP is a Technology Breakthrough in Safety and Reliability for Small Bore Tubing Systems
Design Overview:
- Developed as a critical service, durable design to improve safety at higher pressures and provide easier installation on small bore tubing systems.
- Incorporates design and material technology innovations that allow the fitting to be assembled onto high yield strength and thicker wall tube, compared to conventional compression tube fitting designs.
- Fully validated across a broad range of austenitic and high performance alloys, tubing sizes, and wall thicknesses (inc. 316, 6M0, Super Duplex, 625/825, HC).
- Unique design innovations allow the fitting to be used at higher pressures on thicker walled tubing; in some cases, eliminating the need for less reliable cone and threaded arrangements or more costly welded installation or other permanent methods.
Key Advantages:
- Mechanically Stronger Fitting Nut – 70% more material in high stress areas and 50% more thread engagement means lower make-up torque, plus greater tube holding performance.
- Fitting Ferrule Systems – front ferrule features a sharper delta angle feature to improve sealing on hard/heavy wall tube and rear ferrule provides better gyration control to grip tighter and more reliably on higher yield strength/tough tube (eg. Super Duplex, HC, 625).
- Built in Assembly Gauge – exposed fitting body threads provide a visual indicator to show the fitting is not fully assembled. The assembly condition of the fitting is instantly recognisable and mechanical safety stop prevents overtightening.
