Designed with a patented locking mechanism, this coupler creates a hands-free, leak-proof seal on any Zerk fitting, even under extreme pressures of up to 10,000 PSI. Its unique thumb-lever release allows for effortless disconnection—even from clogged or pressurized fittings—preventing the common issue of broken grease nipples and knuckle injuries. As the only fully rebuildable coupler on the market, it offers the lowest lifetime cost for professional mechanics, farmers, and industrial maintenance teams.\u003c\/p\u003e\u003ch3\u003ePerformance Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatented Locking Technology:\u003c\/strong\u003e Four hardened spring steel jaws lock securely onto the Zerk fitting and will not pop off under high pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHands-Free Operation:\u003c\/strong\u003e Once locked on, both hands are free to operate the grease gun, ensuring grease goes into the machine rather than around the fitting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Pressure Rated:\u003c\/strong\u003e Safely handles working pressures up to 10,000 PSI (690 Bar).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Standard 1\/8\" NPT thread fits all manual, battery, and pneumatic grease guns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRebuildable Design:\u003c\/strong\u003e Features a replaceable seal and jaws, significantly extending the tool's lifespan compared to disposable alternatives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Release Trigger:\u003c\/strong\u003e The integrated thumb lever enables quick release from pressurized or stubborn fittings without tugging or twisting.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU \/ Model\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eGC81011\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThread Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1\/8\" NPT (Female)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10,000 PSI (690 Bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHardened Steel with Nitrile Rubber Seal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoupler Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e16 mm (5\/8\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoupler Length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e88 mm (3-1\/2\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eZerk Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAll SAE and Metric (DIN) specifications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeal Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHigh-Performance Nitrile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003e\u003c\/h3\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 x LockNLube GC81011 Grease Coupler\u003c\/li\u003e\n\u003cli\u003e1 x Spare Rebuild Kit (Replacement Seal and Hardened Steel Jaws)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCKNLUBE","offers":[{"title":"Default Title","offer_id":53640514994542,"sku":"GC81011","price":39.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/0333\/6025\/files\/Untitled-2026-04-20T092558.565_1.jpg?v=1776652018","url":"https:\/\/wiselinetools.ca\/products\/locknlube-gc81011-original-grease-coupler","provider":"Wise Line Tools","version":"1.0","type":"link"}
