SIEVERT 3002-90 female quick connect

The SIEVERT 3002-90 is a female gas quick connect fitting designed for welding gas supply lines. It suits professional welders and hobbyists who need a secure 9/16 inch connection point for their torch or regulator setup. This component integrates into existing gas distribution systems.

Installation uses standard 9/16 thread

Installation involves threading the 9/16 inch female end onto a compatible male fitting using appropriate wrenches. The quick connect mechanism allows rapid coupling and uncoupling of gas hoses once the fitting is secured. Common issues include cross-threading during initial engagement or leaks from worn internal seals if the mating surfaces are damaged.

Suits 9/16 inch gas system builds

This fitting suits anyone assembling or repairing a welding gas system that uses the 9/16 inch thread standard. It is not for users requiring different thread sizes such as 1/4 NPT or metric variants. Buyers needing a male quick connect or a complete hose assembly should look at other components.

Questions about this item

How do I confirm the SIEVERT 3002-90 quick connect is sealing properly after installation?

Pressurise the gas line and apply leak detection fluid to the 9/16 inch female fitting; bubbles indicate a leak while a steady pressure reading confirms a sound seal.

What comes with the SIEVERT 3002-90 and what must I source separately?

The package contains the female 9/16 inch quick connect body only; a matching male plug, gas hose, clamps and thread sealant are sold separately.

Which SIEVERT quick connect version should I choose for a 9/16 inch torch fitting?

Select the 3002-90 model; the 90 suffix identifies the 9/16 inch female thread size required for that torch connection.
