At $79, it is inexpensive insurance against a repeat teardown or a fluid leak after reassembly — always include it in the parts order when the surrounding assembly is being serviced.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon customer questions:\u003c\/strong\u003e The most frequent question is whether the original O-ring can be reused if it looks fine — it cannot. Compression set and micro-cracking are not always visible, and a failed seal after reassembly costs far more in labour than the cost of a new ring. Customers also ask about aftermarket substitutes — OEM is always the safest choice for material compatibility with Volvo Penta fluids and operating conditions.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563975933988,"sku":"1546221","price":79.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/1546221.png?v=1771697706","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-sealing-ring-1546221","provider":"Marisol Marine Company","version":"1.0","type":"link"}
