GYROLOK Authorised Distributor in India

Priminox Overseas is the Authorised Distributor & Stockist of GYROLOK in India. We hold ready stock of GYROLOK twin-ferrule tube fittings, valves with integral GYROLOK end connections, adapters, specialty fittings, and GYROLOK XP high-pressure fittings at our Mumbai warehouse, with most common configurations available ex-stock and speciality alloys on request. HOKE introduced the GYROLOK tube fitting in the early 1960s, and the design has set the benchmark for instrumentation compression fittings ever since. GYROLOK is part of Crane Instrumentation & Sampling. We supply GYROLOK products into oil and gas, refining, chemical and petrochemical, hydrogen service, power generation, and analyser and sample-conditioning systems, where engineers value leak-tight performance, repeat-make reliability, and full material traceability. Every consignment ships with original HOKE GYROLOK factory marking, a Certified Material Test Report (CMTR), and a Certificate of Conformity.

Tube socket weld and butt weld connectors and elbows are available for permanent installations.

Fractional tube sizes run from 1/16 inch to 2 inch outer diameter, with metric equivalents from 3 mm to 38 mm.

GYROLOK Valves

HOKE valves are available with integral GYROLOK end fittings, combining the valve body and the GYROLOK tube connection in a single assembly. This removes the need for a separate tube fitting at the valve port, eliminates a potential leak path, and extends valve life by preventing end-connection expansion. Integral-GYROLOK valves are supplied across the HOKE valve range, including ball valves (Flomite, Selectomite, DL/TL series), needle and metering valves (Milli-Mite, Micromite, Micro-Mite), check valves, bleed valves, and relief valves, in fractional and metric tube sizes.

GYROLOK Adapters

GYROLOK adapters include male adapters with NPT, RT, RS, and RG threads, female adapters, SAE male adapters, O-ring straight and O-ring male adapters, and bulkhead adapters. The adapter range allows engineers to extend, change thread standard on, or convert a GYROLOK port to a different connection without losing the controlled-ferrule-drive seal at the tube end.

GYROLOK XP High-Pressure Fittings

GYROLOK XP is the high-pressure variant of the GYROLOK design, developed for heavy-wall and high-yield-strength tubing used in severe service. The XP nut carries approximately 70% more material in the high-stress area and the connection provides around 50% more thread engagement, allowing the fitting to grip thicker-walled tube. Working pressures can be up to 80% higher than conventional GYROLOK on the same tube outer diameter. The XP range is validated across 316/316L stainless steel, Alloy 6Mo, Super Duplex 2507, Alloy 625, Alloy 825, and Alloy C-276.

GYROLOK Specialty Fittings and Bonded Seals

The specialty range covers calibration fittings for differential pressure transmitters, chromatography fittings, dielectric fittings, thermocouple connectors, heat exchanger tees, and RS bonded seals. GYROLOK fittings can also be supplied cleaned for oxygen service (HPS18 suffix) or for nuclear service (HPS90 suffix) when application standards require it.
