# 421158 Sealing Ring | Genuine Volvo Penta Part ## 🔧 Product Description Genuine Volvo Penta sealing ring from the Engine group, listed for 309 applications across the D, TAD, MD, TMD, TD and AQD series — one of the most widely used small seals in the range. ## 🚤 Compatibility - **Engine Family:** D, TAD, MD, TMD, TD, AQD, TAMD, AQAD, TWD, TID, THAMD, KAD Full model list at the end of this description. ## ⚙️ Key Features - 309 applications across six engine series - A common small sealing ring rather than a model-specific one - Quantity varies by assembly, most commonly one ## 🔌 Function Seals a threaded or spigoted joint by deforming between the two faces as they are tightened. ## ⚠️ Common Signs of Failure - Slow weep or damp film at the joint after running - Ring flattened, hardened or split on removal - Ring stuck to one face and torn when the joint was opened - Drip that returns soon after the joint is simply retightened ## 🛠️ Service Notes - The published weight is too low to identify the part by, so order strictly by part number - Renew rather than reuse — retightening a flattened ring is what usually turns a weep into a drip ## 🔄 Supersession & Cross Reference ### OEM / Related Numbers - 424342 referenced in the part notes ## 📦 Condition -
