3M 7000002157 Facepiece Head Harness Plastic 5 Pack

Product Description

The 3M 7000002157 is a plastic replacement head harness designed for use with 3M half mask facepieces. The harness secures the respirator facepiece against the wearer's face, maintaining a proper seal during use in environments requiring respiratory protection. This component is a direct OEM-style replacement part, sold in a package of five units. It is installed by safety professionals, industrial hygienists, or trained workers performing routine respirator maintenance. Keeping head harnesses in serviceable condition is a core requirement of any OSHA-compliant respiratory protection program.

This head harness is suited for use in industrial, construction, manufacturing, and maintenance environments where 3M half mask respirators are part of the personal protective equipment inventory. It is a standard replacement component used during scheduled respirator inspections or when an existing harness shows signs of wear, cracking, or loss of elasticity. Each unit ships individually as part of a five-count package, making it practical for facilities managing multiple respirators.

Installation Notes

Replacement of respirator components should be performed by a qualified person following the manufacturer's maintenance instructions and in accordance with the site respiratory protection program. Power down any nearby equipment that could generate airborne hazards before removing an in-service respirator for maintenance. After installing the replacement harness, conduct a user seal check per OSHA 29 CFR 1910.134 guidelines before the respirator is returned to service. Do not modify the harness or facepiece assembly in any way that deviates from the manufacturer's design.
