The fill cap seals the front-of-dash fill port on the helm, preventing fluid loss and contamination ingress between fluid top-offs and system service. If the original cap is lost, cracked, or damaged, the 40800L provides a direct replacement to keep the hydraulic system sealed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Non-vented fill port cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Uflex UP series hydraulic steering helms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 40800L | SKU: 216-40800L\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUflex \u003ca href=\"\/products\/front-mount-helm-216-up20fm\"\u003eUP20FM\u003c\/a\u003e, \u003ca href=\"\/products\/front-mount-helm-216-up25fm\"\u003eUP25FM\u003c\/a\u003e, and \u003ca href=\"\/products\/uflex-up28fm-front-mount-helm-216-up28fm\"\u003eUP28FM\u003c\/a\u003e front-mount hydraulic helms\u003c\/li\u003e\n\u003cli\u003eUflex \u003ca href=\"\/products\/back-mount-helm-216-up28r\"\u003eUP28R\u003c\/a\u003e and \u003ca href=\"\/products\/back-mount-helm-216-up39r\"\u003eUP39R\u003c\/a\u003e rear-mount hydraulic helms\u003c\/li\u003e\n\u003cli\u003eUflex \u003ca href=\"\/products\/front-mount-tilt-helm-216-up25tx52\"\u003eUP25TX52\u003c\/a\u003e, \u003ca href=\"\/products\/front-mount-tilt-helm-216-up28tx52\"\u003eUP28TX52\u003c\/a\u003e, and \u003ca href=\"\/products\/front-mount-tilt-helm-216-up33tx52\"\u003eUP33TX52\u003c\/a\u003e tilt helms\u003c\/li\u003e\n\u003cli\u003eUflex \u003ca href=\"\/products\/silversteer-front-mount-helm-pump-1-5-cubic-inch-216-up25fsvs\"\u003eUP25FSVS\u003c\/a\u003e and \u003ca href=\"\/products\/silversteer-front-mount-helm-pump-2-0-cubic-inch-216-up33fsvs\"\u003eUP33FSVS\u003c\/a\u003e SilverSteer™ helms\u003c\/li\u003e\n\u003cli\u003eVerify cap fitment with your specific helm model before ordering — confirm the 40800L is the correct non-vented cap for your helm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The 40800L is the correct cap when the fill port cap on your Uflex UP series helm is lost or damaged — a small but important part, as a missing fill cap allows hydraulic fluid to weep out of the fill port under pressure and allows water and contamination to enter the system. The non-vented design keeps the system fully sealed between service intervals. It’s worth keeping a spare on board, as the cap is easy to misplace during fluid top-offs. Confirm the 40800L is the correct cap for your specific helm model before ordering — some Uflex helms use a vented cap rather than a non-vented cap, and the two are not interchangeable.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51250854494244,"sku":"216-40800L","price":33.39,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/216-40800L.jpg?v=1786511131","url":"https:\/\/marisolmarine.com\/products\/non-vented-replacement-cap-216-40800l","provider":"Marisol Marine Company","version":"1.0","type":"link"}
