Later serial numbers may use a different seal. Confirm by serial number and the correct parts diagram for your engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does 864723 replace 471449?\u003c\/strong\u003e\u003cbr\u003eYes. 864723 is the current Volvo Penta OEM reference that supersedes the earlier 471449. If your diagram shows 471449, 864723 is the correct current part to order.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the sealing ring after removing the pipe connection?\u003c\/strong\u003e\u003cbr\u003eVolvo Penta workshop practice is to replace the sealing ring whenever the joint is disassembled. A compressed ring that has been in service may not reseal correctly after removal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this the same ring used on all engines in the compatibility list?\u003c\/strong\u003e\u003cbr\u003eThe part number is the same across all listed applications, but the early-type designation means it is specific to certain serial ranges. Always cross-reference your engine serial number against the applicable parts diagram.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003eThe detail that matters most with 864723 is the \u003cstrong\u003eearly-type designation\u003c\/strong\u003e. This sealing ring covers a very wide range of Volvo Penta diesel families — from the 31 and 41 series through the large TAMD 61–75 engines — but that broad coverage only applies to engines within the earlier production serial ranges. The most common issue we see is customers ordering by engine model without confirming the serial break. If your engine is at the upper end of any of the listed production ranges, confirm the serial number against the Volvo Penta diagram before ordering. While you have the pipe connection apart, it is also worth inspecting the adjacent clamp and O-ring at the same time — the labour to come back and fix a leaking clamp or failed O-ring after reassembly is not worth the cost of skipping those components during service.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564051791908,"sku":"864723","price":24.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/ff962c83-d336-418c-a27c-8a427423a180.png?v=1789511570","url":"https:\/\/marisolmarine.com\/products\/volvo-1122","provider":"Marisol Marine Company","version":"1.0","type":"link"}
