70A15 - ESAB 70A15 Diaphragm Plate for R-52 Regulators

Restore Your Regulator's Performance

Keep your trusty Purox R-series regulator in top fighting shape with the ESAB 70A15 Diaphragm Plate. If you are rebuilding an older R-50, R-51, or R-52 regulator, this is the genuine part you need to ensure the spring pressure is applied correctly to the diaphragm. A worn, pitted, or bent plate can lead to erratic pressure readings and unstable flow, making your torch work inconsistent and frustrating.

Don't settle for generic knock-offs when it comes to gas equipment safety. This OEM part from ESAB (formerly Purox/Linde) guarantees the correct dimensions and material strength to handle the rigors of daily shop use. Whether you are fixing a creeping pressure issue or performing routine maintenance on your oxy-fuel setup, this diaphragm plate is a key piece of the puzzle to get your equipment back to factory specs.

Installation is straightforward for those experienced in regulator repair. Simply disassemble the bonnet, remove the control spring and the old plate, and seat the new 70A15 plate atop the diaphragm before reassembly. This small but mighty part ensures your pressure adjustment knob translates into smooth, predictable gas flow. Weld, cut, and braze with confidence knowing your pressure control is precise and reliable.
