35Z81 - Purox R-52 Diaphragm Attaching Screw

Restore Your Purox Regulator with the ESAB 35Z81 Screw

Don't let a stripped or missing screw render your heavy-duty regulator useless. The ESAB 35Z81 Diaphragm Attaching Screw is the exact OEM part you need to get your Purox R-52, R-51, or R-50 regulator back in action. In the world of welding and metal fabrication, your equipment is your livelihood, and the regulator is the heart of your gas delivery system. When it comes time to service or rebuild these durable units, every component matters. This specific screw is designed to hold the diaphragm assembly together securely, ensuring your regulator delivers the smooth, consistent gas flow you rely on for precision cutting and welding.

The Purox R-series regulators are legendary for their toughness, often lasting for decades with proper care. However, maintenance is key to that longevity. During a rebuild, it is common to find internal screws that have seized, corroded, or suffered thread damage. Trying to force a damaged screw back in, or using a generic hardware store replacement, is a recipe for disaster. Generic screws may not have the correct tensile strength or thread profile, leading to a loose diaphragm assembly. A loose assembly means fluctuating pressures, poor flame characteristics, and potential safety hazards. The ESAB 35Z81 eliminates this risk by providing a factory-perfect fit.

This replacement part is easy for qualified technicians to install during a standard regulator overhaul. It integrates seamlessly with the existing diaphragm and stem components of your R-series unit. Whether you are fixing a leak, correcting pressure creep, or simply performing a scheduled overhaul, having the right small parts on hand makes the job go smoother and faster. Investing in genuine repair parts is always cheaper than buying a new regulator, especially when dealing with high-end industrial models like the R-52.
