A Rinnai 109001410 O-Ring forms a dependable seal at pipe connections to reduce leakage and support steady performance in the equipment.
The o-ring forms a tight seal at pipe connections so the HVAC system can maintain proper pressure and fluid or gas flow during operation. Its round construction and sealing material matter because they allow it to compress evenly, resist leaks and support reliable performance in heating and cooling equipment.
The o-ring may be failing if the unit shows leaks, pressure loss or inconsistent heating and cooling performance during operation. Physical signs can include cracking, flattening or brittleness and you might notice moisture buildup, dripping near pipe joints or other environmental signs that could point to a worn seal.
