Description
The Trane RNG02126 Refrigerant O-Ring 34.0″ ID × 0.275″ RD is a sealing element used to maintain airtight integrity at connection points within pressurized cooling circuits, preventing leakage between metal mating surfaces under operating conditions. It works through flexible compression, where the ring deforms within a groove to create a tight barrier that preserves internal pressure stability and ensures continuous flow performance. In HVAC systems used in air conditioning and heat pump equipment, it is positioned at service joints, valves, or flange interfaces within the sealed line assembly. The component is mounted in machined grooves for uniform compression and sealing effectiveness.
