Gyrolok® and Griplok Stainless Instrumentation Fittings Intermix & Interchangeability

Griplok tube fittings are devised and constructed and sold to be completely “interchangeable” with Hoke® Gyrolok® tube fittings. The high-quality manufacturing of the products to exacting tolerances under demanding quality control processes serves to ensure high levels of both safety, and performance. This is accomplished while also providing reliable service wherever Gyrolok and Griplok tube fittings are implemented in line with established installation and service procedures.

Griplok Technology

Griplok tube fittings make use of a two-ferrule design with exceptional geometry, precision machining, and unequaled material quality, to deliver leak-tight remakeable seals even during applications involving high vibration and significant temperature changes. This leak-tight seal results from the sequential interaction of the nut, front and back ferrules, the body, and the tubing.

Griplok Technology

 

Materials

Griplok tube fittings are machined from type 316 stainless steel cold-finished bar stock in agreement with ASTM A-276 and ASTM A-479. Elbows, tees, and crosses are constructed from close-grained 316 stainless steel forgings in compliance with ASTM A-182. All 316 stainless steel. All parts are heat code traceable.

Packaging

Griplok tube fittings are fabricated and bagged individually in order to deliver the best levels of quality and hygiene available. The fittings are provided in packaging that is easy to use and comes in small lots to simplify procurement and handling.
