It is made for boats that already use the 1270 fill style and need a correct replacement cap for gas, diesel, or water service.\u003c\/p\u003e\u003cp\u003eThis cap range is non-vented and includes the matching cap type marking, so the deck fill remains easy to identify during fueling or water fill-ups. Each configuration is supplied with an O-ring and retainer, which helps keep the cap sealed and attached at the fill point during normal use on deck.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003ePolymer cap for Perko Figure No. 1270 fuel and water fills.\u003c\/li\u003e\n\u003cli\u003eAvailable in gas, diesel, and water versions so the cap marking matches the deck fill service.\u003c\/li\u003e\n\u003cli\u003eNon-vented 1270-style cap for use with the correct matching fill and system layout.\u003c\/li\u003e\n\u003cli\u003eIncludes an O-ring and retainer for a proper cap replacement at the deck fill.\u003c\/li\u003e\n\u003cli\u003ePractical spare for boats where the original fill cap is worn, missing, cracked, or hard to secure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis replacement cap is offered in multiple configurations for different fill services on board.\u003c\/p\u003e\u003cp\u003eThe service marking changes by variant, while the 1270 replacement cap style, polymer cap construction, O-ring, and retainer remain consistent across the range.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1270DPG99A: Gas cap.

This version is marked for diesel deck fills, helping separate fuel types clearly at the deck fitting.\u003c\/li\u003e\n\u003cli\u003e1270DPW99A: Water cap. This version is marked for water fills, making it easier to distinguish potable water access from fuel fill points.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eUse this cap only as a replacement for the Perko 1270 fill style. The part should match the existing cap type on the boat, including the service marking and the non-vented configuration. For gas installations, confirm that the vessel uses the compatible non-EPA fill style before replacing the cap.\u003c\/p\u003e\u003ch6\u003eInstallation and use\u003c\/h6\u003e\u003cp\u003eInstallation is straightforward when the existing deck fill is already a Perko 1270 style. Remove the damaged or missing cap assembly, check that the fill neck and sealing surface are clean, and fit the replacement cap with its O-ring and retainer in place. A clean sealing surface matters on deck, where spray, washdowns, fuel residue, and dirt can affect how the cap seats.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis cap is a good match for boat owners, service yards, and marine technicians replacing a lost or worn cap on an existing Perko 1270 deck fill. It is especially useful as a spare aboard cruising boats, fishing boats, and workboats where a missing fill cap can quickly become a water intrusion or contamination problem.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse the cap area with fresh water after saltwater exposure and check the O-ring periodically for wear, flattening, or cracking. Replace the cap if it no longer tightens correctly, if the retainer is damaged, or if the service marking is no longer readable.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eReplacement cap\u003c\/li\u003e\n\u003cli\u003eO-ring\u003c\/li\u003e\n\u003cli\u003eRetainer\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Perko","offers":[{"title":"Gas","offer_id":52581974245557,"sku":"QBP979089-V1","price":30.48,"currency_code":"USD","in_stock":true},{"title":"Diesel","offer_id":52581974278325,"sku":"QBP979089-V2","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Water","offer_id":52581974311093,"sku":"QBP979089-V3","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334870_qbp979089.webp?v=1780201928","url":"https:\/\/www.qualityboatparts.com\/products\/qbp979089","provider":"Quality Boat Parts","version":"1.0","type":"link"}
