# 20365079 Rubber Washer | Genuine Volvo Penta Part ## 🔧 Product Description Genuine Volvo rubber sealing washer fitted beneath oil filler cap 20807510 on selected D7, D9, D12, D13 and D16 engines. The EPDM-style rectangular seal closes the filler neck and prevents oil mist and contamination passing around the cap. ## 🚤 Compatibility - **Engine Family:** D, TAD, TWD, TADH - **HP Range:** 110-220 HP Full model list at the end of this description. ## ⚙️ Key Features - Oil-resistant rubber filler-cap seal - Fits the sealing groove beneath oil filler cap 20807510 - Approximate aftermarket dimensions: 39.67 mm inside diameter and 5.53 mm section - Prevents oil mist leakage and dirt entry - Should be renewed if flattened, hard or swollen - Engine type: Volvo Penta 7-, 9-, 12- and 16-litre diesel ## 🔌 Function Seals the oil filler cap to the filler neck while allowing the cap to be removed for engine-oil servicing. ## ⚠️ Common Signs of Failure - Oil mist or wetness around the filler cap - Dust entering around the cap - Seal flattened, cracked or swollen - Cap no longer tightening securely - Oil odour or staining on the valve cover ## 🛠️ Service Notes - Sits beneath oil filler cap 20807510 specifically — confirm the cap fitted to your engine before ordering, as this seal is sized to that cap rather than a generic filler neck - Approximate aftermarket dimensions are 39.67 mm inside diameter with a 5.53 mm section — check a removed seal against these before assuming a different rubber washer in the range will substitute - Renew if flattened, hard or swollen rather than reusing; EPDM seals harden with age and heat around the filler neck ## 🔄 Supersession & Cross Reference ### OEM / Related Numbers - 20807510 - related oil filler cap ### Aftermarket / Verified Equivalents - PAI 821089 - equivalent rectangular sealing ring - DT Spare Parts 2.10219 - equivalent sealing washer ## 📦 Condition - Genuine Volvo Penta part - Brand new - Supplied in original or equivalent packaging ## 🔎 Full Model Compatibility Typically suits: - Volvo Penta D3-220I-G, D3-140A-D, D3-170A-D, D3-200A-D, D3-220A-D, D3-140I-D, D3-140A-E, D3-170A-E, D3-200A-E, D3-220A-E, D3-140I-E, D3-140A-F, D3-170A-F, D3-200A-F, D3-220A-F, D3-140I-F, D3-140A-G, D3-170A-G, D3-200A-G, D3-220A-G, D3-140I-G, D3-110I-D, D3-150I-D, D3-170I-D, D3-200I-D, D3-220I-D, D3-110I-E, D3-150I-E, D3-170I-E, D3-200I-E, D3-220I-E, D3-110I-F, D3-150I-F, D3-170I-F, D3-200I-F, D3-220I-F, D3-110I-G, D3-150I-G, D3-170I-G, D3-200I-G, D3-110I-H, D3-140A-H, D3-170A-H, D3-200A-H, D3-220A-H, D3-150I-H, D3-170I-H, D3-200I-H, D3-220I-H, D3-140I-H - Volvo Penta D13C3-B MH, D13C1-B MH, D13C4-B MH, D13C2-B MP, D13C1-A MP, D13C2-A MP, D13C3-A MP, D13C4-A MP, D13B-A MP, D13B-H MP, D13B-G MP, D13B-L MP, D13B-E MG, D13B-E MG (FE), D13B-E MH, D13B-E MH (FE), D13B-F MG, D13B-F MG (FE), D13B-K MP, D13B-N MH, D13B-N MH (FE), D13B-B MP, D13B-D MP, D13B-J MP, D13B-M MP, D13B-C MP, D13C4-B MP, D13C5-B MP, D13C6-A MP, D13C1-A MH, D13C2-A MH, D13C1-B MG, D13C3-B MG, D13C2-B MG, D13C4-B MG, D13C5-A MP, D13C2-A MG, D13C1-A MG, D13C7-B MP, D13C8-B MP, D13C9-A MP - Volvo Penta D11C1-A MP, D11C3-A MP, D11C2-A MP, D11C4-A MP, D11B3-A MP, D11B4-A MP, D11A-C, D11A-E, D11B2-A MP, D11A-C MP, D11A-D MP, D11A-E MP, D11A-C (IPS), D11B1-A MP - Volvo Penta D8A2-A MP, D8A5-A MH, D8A6-A MH, D8A5-A MG, D8A6-A MG, D8A4-A MP, D8A1-A MP, D8A3-A MP, D8A7-A MP, D8A8-A MP - Volvo Penta D12C-A MP, D12D-A MG, D12D-A MH, D12D-B MH, D12D-C MH, D12D-E MG, D12D-E MH, D12D-G MH - Volvo Penta D16C1-E MG, D16C1-F MG, D16C2-E MG, D16C2-F MG, D16C1-E MH, D16C1-F MH, D16C2-E MH, D16C2-F MH - Volvo Penta D9A2J, D9A2G, D9A2L MH, D9A2F, D9A2K, D9A2H, D9A2M MP, D9A2E - Volvo Penta TAD1640-42GE-B, TAD1640GE, TAD1640VE-B, TAD1640-42VE-C - Volvo Penta TAD840GE, TAD840-43VE, TAD840GE-B, TAD840-43VE-C - Volvo Penta TAD1241GE, TAD1241VE, TAD1241-42VE - Volvo Penta TAD1341-43GE-B, TAD1341VE, TAD1341GE - Volvo Penta TAD1344-45GE-B, TAD1344VE, TAD1344GE - Volvo Penta TAD1641VE-B, TAD1641GE, TAD1641VE - Volvo Penta TAD1642VE-B, TAD1642GE, TAD1642VE - Volvo Penta TAD1650VE-B/51VE, TAD1650GE, TAD1650VE - Volvo Penta TAD1242GE, TAD1242VE - Volvo Penta TAD1250VE, TAD1250-52VE - Volvo Penta TAD1342VE, TAD1342GE - Volvo Penta TAD1343VE, TAD1343GE - Volvo Penta TAD1345GE, TAD1345VE - Volvo Penta TAD1350GE, TAD1350VE - Volvo Penta TAD1351GE, TAD1351-53VE - Volvo Penta TAD1643VE-B, TAD1643VE - Volvo Penta TAD540-42VE, TAD540-42VE-C - Volvo Penta TAD550-51VE, TAD550-52VE-C - Volvo Penta TAD570-72VE, TAD570-71VE-B - Volvo Penta TAD850-52VE, TAD850-52VE-C - Volvo Penta TAD880-82GE, TAD880-84VE - Volvo Penta TADH880-82GE, TADH880-84VE - Volvo Penta TWD1683GE-B, TWD1683VE - Volvo Penta TAD1140-42VE - Volvo Penta TAD1150-52VE - Volvo Penta TAD1170-72VE - Volvo Penta TAD1180-83VE - Volvo Penta TAD1240GE - Volvo Penta TAD1251VE - Volvo Penta TAD1252VE - Volvo Penta TAD1340VE - Volvo Penta TAD1346GE - Volvo Penta TAD1352GE - Volvo Penta TAD1353GE - Volvo Penta TAD1354GE - Volvo Penta TAD1355GE - Volvo Penta TAD1360-62VE - Volvo Penta TAD1363-65VE - Volvo Penta TAD1371-75VE - Volvo Penta TAD1380-82GE - Volvo Penta TAD1381-85VE - Volvo Penta TAD1384-85VE-IWP - Volvo Penta TAD1651GE - Volvo Penta TAD1660-62VE - Volvo Penta TAD1662VE EU5 - Volvo Penta TAD1670-72VE - Volvo Penta TAD552VE - Volvo Penta TAD580-83VE - Volvo Penta TAD841-43GE - Volvo Penta TAD851-53GE - Volvo Penta TAD852VE-B - Volvo Penta TAD853VE - Volvo Penta TAD870-73VE - Volvo Penta TAD940VE - Volvo Penta TAD941VE - Volvo Penta TAD942VE - Volvo Penta TAD943VE - Volvo Penta TWD1240VE - Volvo Penta TWD1643GE - Volvo Penta TWD1644-45GE - Volvo Penta TWD1652GE - Volvo Penta TWD1653GE - Volvo Penta TWD1663GE - Volvo Penta TWD1672-1673GE - Volvo Penta TWD1682-83GE - Volvo Penta TWD1744GE ## Details - **Price:** 11.03 AUD - **Vendor:** Volvo Penta - **Type:** Fasteners & Fixings - **Tags:** Volvo Penta ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 11.03 AUD | In stock | ## Images - 20365079 Rubber Washer | Genuine Volvo Penta Part - 20365079 Rubber Washer | Genuine Volvo Penta Part - photo 2 of 2 --- > Source: [Sawley's Auto and Marine](https://www.sawleysautoandmarine.com.au/products/20365079-rubber-washer-genuine-volvo-penta) > Updated: 2026-10-10
