The \u003cstrong\u003e008-005RP\u003c\/strong\u003e O‑ring is engineered for select 00‑series models, offering a precise fit and durable material that stands up to the thermal cycles typical in hydronic systems.\u003c\/p\u003e\u003cp\u003eDesigned from EPDM, the ring compresses uniformly against the casing groove, creating a resilient barrier that accommodates minor shaft movement while resisting degradation from hot water and chemicals.
