Heat Exchanger Plate O-Ring
The Heat Exchanger Plate O-Ring is a high-temperature, pressure-resistant elastomeric seal designed to secure a watertight connection between the secondary plate heat exchanger and the hydraulic block. Engineered to withstand continuous thermal cycling, this crucial sealing component prevents water leaks under system pressure, ensuring domestic hot water and central heating water circuits remain completely isolated.
High-Grade Elastomeric Compound: Manufactured from premium rubber to resist chemical degradation, scale build-up, and continuous exposure to high hot water temperatures.
Leak & Pressure Drop Prevention: Replaces warped, flattened, or brittle seals to eliminate dripping under the boiler jacket, directly resolving chronic system pressure drops.
Precise Seating Geometry: Molded to exact specifications to guarantee an immediate, secure compression seal within the hydro-block ports during exchanger installation.
