It connects the grease gun hose to a zerk fitting at a right angle, allowing lubrication of fittings in tight or awkward spaces where a straight coupler cannot reach. The coupler features a 1\/8 inch NPT connection and is rated for a maximum working pressure of 4,500 psi, with a burst pressure rating of 8,000 psi. Licensed technicians and maintenance professionals working on vehicles, heavy equipment, and industrial machinery rely on this fitting for reliable, leak-free grease delivery under full operating pressure.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for general lubrication service in automotive, fleet, agricultural, and light industrial applications. It is particularly useful when servicing chassis fittings, ball joints, tie rod ends, U-joints, and other grease points that are recessed or angled in a way that blocks direct coupler access. The swivel design allows the coupler body to rotate after engagement, reducing hose stress and improving access angle during the greasing process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree swivel design provides access to hard-to-reach zerk fittings\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 4,500 psi for use with standard hand-operated grease guns\u003c\/li\u003e\n  \u003cli\u003eBurst pressure rating of 8,000 psi adds a substantial safety margin\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch NPT connection fits standard grease gun hose ends\u003c\/li\u003e\n  \u003cli\u003eSwivel body rotates after locking onto the fitting to reduce hose kink and strain\u003c\/li\u003e\n  \u003cli\u003eCompatible with most hand-operated grease guns without additional adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eFits most hand-operated grease guns with a standard 1\/8 inch NPT hose connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the coupler onto the grease gun hose end using the 1\/8 inch NPT connection and tightening with an appropriate wrench — do not overtighten, as NPT fittings are tapered and can crack if over-driven. Before attaching to a grease fitting, relieve any residual pressure in the grease gun. Ensure the coupler jaw fully seats and locks onto the zerk fitting before applying pressure to avoid blowoff. Inspect the coupler for wear or damaged seals periodically, and replace if leakage or loss of grip is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 1\/8 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4,500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBurst Pressure\u003c\/strong\u003e: 8,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupler Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILMAR CORPORATION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W54225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PERFORMANCE TOOL","offers":[{"title":"Default Title","offer_id":51559874363698,"sku":"W54225","price":50.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5fb5811013c0dbc07e0bbde15b6b053.jpg?v=1786443186","url":"https:\/\/voomisupply.com\/products\/wilmar-corporation-w54225-90-degree-swivel-coupler","provider":"Voomi Supply","version":"1.0","type":"link"}
