Ideal Heat Exchanger O'rings 39841660

Ideal Heat Exchanger Washer O-Ring (171031 / 173823) The Ideal Heat Exchanger Washer O-Ring Pack is a high-grade hydraulic sealing component designed to handle the demanding heating and hot water cycles within specific Ideal domestic boilers. Made from premium, heat-resistant EPDM rubber, these O-rings provide a perfectly watertight and leak-proof seal at the primary and secondary plate heat exchanger ports. They prevent internal pressure drops, dripping, and cross-contamination between the heating circuit and domestic hot water supply. High Thermal Stability: Engineered from premium elastomeric compounds that expand and contract reliably under continuous high-temperature shifts without weakening or tracking. Leak & Drop Prevention: Directly eliminates small interface drips and structural pressure drops that occur when original seals flatten or turn brittle over time. Flawless Manifold Seating: Dimensioned precisely to lock cleanly into the hydraulic group seating tracks, reducing the risk of seal distortion or pinching during tightening.
