Griplok® tube fittings use a proven dual-ferrule compression seal to provide leak-tight connections and are especially suited to applications with high vibration such as gas transmission and turbines.
*Griplok tube fittings are rated to the maximum allowable pressure rating of the tubing they connect.
Griplok tube fittings are designed, manufactured, quality controlled and distributed to be totally “interchangeable”with the Hoke® Gyrolok® brand of tube fittings. The precision manufacturing of both products to stringent tolerances under rigid quality control procedures ensures the safety, performance and reliability of service whenever Gyrolok and Griplok tube fittings component parts are mixed and used in accordance with published installation and service practices.
Griplok tube fittings use a two-ferrule design with sophisticated geometry, precise machining, unsurpassed material quality, to provide a leak-tight remakeable seals even in applications having high vibration and extreme temperature changes. This leak-tight seal is the result of the sequential interaction of the nut, the front and back ferrules, the body, and the tubing.
Griplok tube fitting straight configurations are machined from type 316 stainless steel cold-finished bar stock in accordance with ASTM A-276 and ASTM A-479. Elbows, tees and crosses, are machined from close-grained 316 stainless steel forgings in accordance with ASTM A-182. All 316 stainless steel. All components are heat code traceable. Certified material test reports (CMTRs) are available.
