If the original cap on a gas or diesel deck fill is lost, damaged, or worn out, this cap restores the fitting to like-new function without replacing the entire deck fill assembly.\u003c\/p\u003e\u003cp\u003eThe cap uses a slotted design that requires a deck fill key to open and close, adding a layer of security against tampering or unauthorized access to the fuel or water fill. It is constructed of investment cast 316 stainless steel for corrosion resistance in a marine environment, matching the material used across the deck fill line it belongs to. The cap measures 1-7\/8 inches in diameter with an 11-1\/2 NPSM straight thread pitch, matching the threads on the 351520-351523 deck fill bodies.\u003c\/p\u003e\u003cp\u003eAn attachment cable (0P35105) is included with the cap so it stays tethered to the deck fill and cannot be dropped or lost overboard during use. A flange gasket for 1-1\/2 inch deck fills (351349) is sold separately and is not included with this cap. The 351390-1 weighs 0.22 pounds.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 351390-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Deck Fill Models:\u003c\/strong\u003e 351520-351523\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Investment cast 316 stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Diameter:\u003c\/strong\u003e 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 11-1\/2 NPSM straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Cable:\u003c\/strong\u003e Included (0P35105)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket:\u003c\/strong\u003e Sold separately (351349)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.22 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514351010\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eSea-Dog 1-1\/2 inch angled hose deck fills, part numbers 351520-351523\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eNo cross-reference numbers listed\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat deck fills does the Sea-Dog 351390-1 cap fit?\u003c\/strong\u003e The 351390-1 is a replacement cap for Sea-Dog's 1-1\/2 inch angled hose deck fills, part numbers 351520-351523.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a key to open this deck fill cap?\u003c\/strong\u003e Yes, the 351390-1 uses a slotted cap design that requires a deck fill key to open and close, which adds security against unauthorized access.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the 351390-1 cap made of?\u003c\/strong\u003e It is constructed of investment cast 316 stainless steel, matching the material used across Sea-Dog's angled hose deck fill line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size and thread does the cap use?\u003c\/strong\u003e The 351390-1 cap has a diameter of 1-7\/8 inches with an 11-1\/2 NPSM straight thread pitch, matching the 351520-351523 deck fill bodies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the replacement cap come with an attachment cable?\u003c\/strong\u003e Yes, the 351390-1 includes attachment cable 0P35105 so the cap stays tethered to the deck fill and cannot be dropped or lost.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the gasket included with the 351390-1 cap?\u003c\/strong\u003e No, the flange gasket for 1-1\/2 inch deck fills (part number 351349) is sold separately and is not included with the 351390-1 cap.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 351390-1 replacement cap weigh?\u003c\/strong\u003e The Sea-Dog 351390-1 cap weighs 0.22 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between the 351390-1 and 351391-1 caps?\u003c\/strong\u003e The 351390-1 is a replacement cap for the 1-1\/2 inch deck fills (351520-351523), while the 351391-1 is a replacement cap for the 2 inch deck fills (351620-351621).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 351390-1 cap fit both gas and diesel deck fills?\u003c\/strong\u003e The 351390-1 fits the 1-1\/2 inch deck fill bodies (351520-351523) regardless of the fuel type marking on the fill, since it is sized to the 1-7\/8 inch cap diameter and 11-1\/2 NPSM thread shared by that series.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this cap need a bonding wire?\u003c\/strong\u003e USCG regulations require a bonding wire on deck fill installations to prevent sparking; this applies to the deck fill assembly the 351390-1 cap is installed on.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 351390-1 cap sold with the deck fill hardware or fasteners?\u003c\/strong\u003e No, the 351390-1 is the replacement cap only; the deck fill assembly installs with three #10 flat head fasteners, which are not included with the cap.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988761325787,"sku":"S-D-351390-1","price":21.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/7144_5eefc388-ed4a-4c1f-9e26-7d43e0dd0736.jpg?v=1784428966","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-351390-1-replacement-deck-fill-cap-with-chain-for-1-1-2-hose-deck-fills-investment-cast-316-stainless-steel","provider":"Good Vibes Marina","version":"1.0","type":"link"}
