680SSHT - CGA 680 Stainless Steel Nut and Nipple Assembly 6000 PSI

Reliable Connections for High-Pressure Testing

When you are dealing with high-pressure cylinders, safety and reliability are not optional—they are a necessity. The Stainless Steel CGA 680 Nut and Nipple Assembly is designed for welders, testers, and gas technicians who need a connection they can trust. Rated for a massive 6000 PSI, this fitting is specifically built for "Bottle Testing" applications where pressures often exceed standard working limits.

If you work with high-pressure Nitrogen or Argon cylinders, you know that brass fittings can wear out, especially if you are constantly swapping bottles on a testing manifold. This unit is machined from tough stainless steel, meaning the threads stay sharp and the hex nut won't round off after a few uses. It is the heavy-duty upgrade your shop needs for filling stations or hydro-test setups.

The CGA 680 connection is the industry standard for high-pressure inert gases. This assembly ensures you can hook up to any standard high-pressure cylinder valve securely. Whether you are pressure testing piping systems, purging lines with high-pressure Nitrogen, or refilling smaller bottles, this nut and nipple set gives you the peace of mind that your connection point is the strongest link in the chain.
