2116734 - ESAB Oxygen Regulator Inlet Filter Replacement

Technical Overview of the ESAB 2116734 Oxygen Inlet Filter

The ESAB 2116734 is a specialized inlet filter designed for use with oxygen regulators in industrial gas applications. Manufactured from high-grade sintered bronze, this component serves as the primary line of defense against particulate contamination entering the high-pressure side of a regulator. In oxy-fuel systems, the cleanliness of the gas stream is paramount not only for the quality of the cut or weld but also for the safety and longevity of the equipment.

Contaminants such as dust, rust, or cylinder scale can easily become dislodged during cylinder transport or connection. Without an effective inlet filter, these particles can travel into the regulator body, potentially scoring the seat or damaging the diaphragm. This can lead to dangerous conditions such as regulator creep (rising outlet pressure) or complete failure. The sintered bronze structure of the 2116734 provides a tortuous path for gas flow, effectively trapping micron-sized particles while maintaining adequate flow rates for standard industrial applications.

This filter is engineered to fit standard oxygen regulator inlet nipples (CGA 540 connections typically used in North America). Regular inspection and replacement of the inlet filter are recommended as part of a preventative maintenance schedule. A clogged filter can result in flow starvation, while a damaged filter compromises safety. As a genuine ESAB part, it ensures dimensional accuracy and material compatibility with oxygen service requirements, adhering to strict industry standards for cleaning and degreasing to prevent combustion hazards.

Installation involves seating the filter within the inlet gland of the regulator. Technicians should ensure that the filter is seated correctly to prevent bypass. This component is compatible with a wide range of ESAB and Victor-style oxygen regulators, making it a versatile spare part for MRO inventories.
