Navien Tankless Water Heaters 20022322A O-Ring EPDM 029.8 X 02.4mm

The Navien Tankless Water Heaters 20022322A EPDM O-ring is a replacement part that serves the HVAC equipment used in Navien. An O-ring is an elastic ring in the shape of a torus that provides a seal between two surfaces that join each other. This particular O-ring is made of EPDM rubber which is sturdy in its ability to negotiate heat, weathering and many aggressive chemicals, which makes it suitable to use in hostile conditions within HVAC systems. This forms a close fit by occupying the interface between two neighboring parts. This reduces the breakout of fluid or gas pressure within the details of the system to avoid cases of leakage.
