Constructed from steel, this cap fits 12 mm (3\/4 inch) hydraulic hose couplers and provides a straightforward mechanical seal to maintain fluid cleanliness and prevent damage to coupler sealing surfaces. Hydraulic technicians and fluid power service professionals install these caps as part of standard port protection practice on mobile and stationary hydraulic systems.\u003c\/p\u003e\u003cp\u003eThis dust cap is suited for use on hydraulic hose assemblies and coupler bodies where a 12 mm male fitting interface is present. It is commonly used in agricultural, construction, industrial, and mobile equipment applications where hydraulic lines are frequently disconnected and reconnected. Keeping coupler faces capped during service intervals reduces the risk of contaminated fluid entering the system and extends the service life of coupler seals and valve components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel construction provides durability and resistance to jobsite handling\u003c\/li\u003e\n\u003cli\u003eMale shaft type fits standard 12 mm hydraulic coupler ports\u003c\/li\u003e\n\u003cli\u003eProtects coupler sealing surfaces from contamination during disconnect\u003c\/li\u003e\n\u003cli\u003e3\/4 inch hose diameter compatibility for common hydraulic line sizes\u003c\/li\u003e\n\u003cli\u003eSold in a package quantity of 5 for typical service and fleet maintenance needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement dust cap for male hydraulic hose couplers with a 12 mm port size and 3\/4 inch hose diameter fitment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eHydraulic fluid power technicians install dust caps as a protective measure whenever coupler connections are broken. Always depressurize the hydraulic circuit and relieve residual line pressure before disconnecting hoses or installing caps. Ensure the coupler face is clean and free of debris before threading the cap into place. Follow applicable equipment manufacturer service procedures and industry hydraulic safety standards during all service work.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupler Dust Cap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PT-00409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540304658738,"sku":"PT-00409","price":142.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b379ba703f99caec78440a6b0c3343ad.jpg?v=1785851643","url":"https:\/\/voomisupply.com\/products\/parker-pt-00409-hydraulic-hose-coupler-dust-cap-12mm","provider":"Voomi Supply","version":"1.0","type":"link"}
