OVERVIEW

Essential Gas Fittings for Professional Equipment

Maintain the integrity of your gas supply lines with the Thermal Dynamics 8-5015 Nut. Specifically designed for oxygen service, this fitting utilizes the standard B-Size (9/16"-18) Right Hand thread, distinguishing it from fuel gas fittings to prevent dangerous cross-connections. It is a critical replacement part for fabricators using Thermal Dynamics plasma systems or standard oxy-fuel cutting torches.

Gas leaks in a welding or cutting environment are not just an annoyance; they are a safety hazard and a drain on resources. The 8-5015 nut is precision-engineered to seat perfectly with compatible tailpieces, creating a gas-tight seal that maintains system pressure and purity. Its brass construction prevents sparking and resists the wear and tear of frequent coupling and uncoupling, making it ideal for shop environments where equipment is often moved or reconfigured.

Whether you are assembling custom hose lengths or replacing stripped hardware on your machine's gas inlet, this nut provides the fit and finish expected from a top-tier manufacturer like Thermal Dynamics. Keep your operations running smoothly and safely by ensuring all your gas connection points are equipped with high-quality, defect-free fittings.
