Description
The Armstrong International A21375 O-Ring 700 forms a sealing barrier between adjoining components to limit fluid or gas leakage at connected joints. It operates in a machined sealing groove, where compression between overlapping surfaces creates a secure seal during equipment operation. Positioned within the required connection point, the sealing ring supports enclosed assemblies in HVAC systems while maintaining the integrity of the joined components. The O-ring maintains sealing performance through balanced compression, secure joint contact, organized sealing support, and controlled leakage prevention.
