22359 - ESAB Purox 22359 Replacement Marginal Spring for R-6700 Regulators

Keep Your R-6700 Regulator Running Smoothly

If your trusty R-6700 regulator isn't holding pressure like it used to, or if you are in the middle of a rebuild, the ESAB 22359 Marginal Spring is the part you need. We know that out in the shop or on the field, your oxy-fuel setup is the lifeline of your operation. A regulator that creeps or fluctuates isn't just annoying—it's a safety hazard and a quality killer for your cuts and welds. This genuine Purox/ESAB spring is the exact replacement for the worn-out coil inside your gear, helping you get back to a steady flame and a safe work environment.

Regulators are tough, but the internal springs take a beating over years of opening and closing valves and adjusting pressures. Metal fatigue is real, and a weak spring can make your gauge needle wander or prevent the regulator from locking out pressure completely. Don't risk your safety or the quality of your work by ignoring the signs of a tired regulator. Swapping out the old spring for this fresh, factory-original 22359 unit is a smart, low-cost investment that extends the life of your expensive equipment.

This isn't a generic hardware store spring; it's calibrated specifically for the heavy-duty R-6700 series. Whether you are running oxygen, acetylene, or another fuel gas, this spring ensures the internal mechanics balance correctly against the gas pressure. It fits perfectly without modification, making your repair job smoother and faster. When you are tearing down your regulator for a clean and check, make sure you have this spring on hand so you don't get stuck waiting for parts.

Why Choose Genuine Parts?

Using genuine ESAB parts means you aren't guessing about fitment or tension. You get the peace of mind that comes with installing a component designed by the same engineers who built the regulator. Keep your torch burning hot and steady by maintaining your regulator with the right parts.
