Split backup ring (.265 ID) for MSA airline respirator quick-disconnect systems and fittings.
This split backup ring is used within MSA supplied-air respirator and airline hose connection systems to provide sealing support and component stability. It is typically installed in quick-disconnect and adapter assemblies where air-supply hoses connect to manifolds or air sources. The ring helps maintain proper sealing performance and prevents deformation of sealing elements under pressure in breathing air distribution setups.
It is commonly used in industrial breathing air systems such as welding, firefighting, utilities, and construction where reliable airline connections are required.
