The Hoke Gyrolok range of instrumentation fittings is now available from Circor in a new line including 316 stainless steel, brass, carbon steel, Monel, Carpenter 20, Hastelloy C276, Inconel, Titanium, 254 SMO, Duplex 2205 and Super Duplex. These materials withstand the most corrosive conditions in chemical processing and extend service life in aggressive offshore applications. Maximum user safety under high pressure or vibration and improved system efficiency through maximised flow are provided by the fittings’ controlled ferrule drive, which also eliminates over-stressing of tubing or excessive reduction of its inside diameter. A butt seal gives a second, series seal and eliminates dead space, while maximising fitting leak integrity and user safety. This feature also increases accuracy in sampling applications and reduces pump down-time in vacuum applications. Leak tight sealing is important in most applications but it is essential in chemical processing where toxic chemicals could injure personnel.
