19147 - ESAB 19147 Replacement Closing Spring for R-27 Regulator

Genuine ESAB Replacement for R-27 Regulators

The ESAB 19147 Closing Spring is a specialized replacement component engineered specifically for the R-27 series of industrial gas regulators. As a critical element of the regulator's internal valve mechanism, this spring provides the necessary closing force to seat the valve against the nozzle, counteracting the diaphragm force to modulate gas pressure effectively. Over time, internal springs can suffer from fatigue, corrosion, or loss of tension, leading to issues such as pressure creep, inconsistent flow rates, or the inability to shut off flow completely.

Sourced directly from ESAB, this OEM part guarantees the correct spring rate, dimensions, and material composition required for the safe operation of R-27 regulators (often associated with the legacy Purox line). Using non-OEM springs in high-pressure gas equipment can compromise safety and performance. This closing spring is essential for MRO technicians and equipment repair specialists looking to refurbish or maintain existing oxy-fuel apparatus to factory standards. It is compatible with standard R-27 assemblies and is easily installed during a standard regulator overhaul.

Maintaining the integrity of gas regulation equipment is paramount in industrial environments. The ESAB 19147 ensures that the delicate balance of forces within the regulator is preserved, providing reliable downstream pressure for welding, cutting, and heating applications. This part is supplied individually and should be inspected whenever a regulator is disassembled for cleaning or repair.
