Featuring nearly 4 inches of reach, this extra-long model maintains the same legendary leak-free and hands-free performance as the original LockNLube coupler. Engineered with a unique sliding sleeve and four hardened spring steel jaws, it creates a rock-solid, leak-proof seal that will not pop off under pressure, even when pushed to 10,000 PSI. The thumb-operated trigger allows for an effortless disconnect, even when the fitting is under extreme back pressure, preventing the common issue of broken fittings or wasted grease.\u003c\/p\u003e\u003ch3\u003ePerformance Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach:\u003c\/strong\u003e Over 3.5 inches (91mm) of effective reach, perfect for U-joints, harvester heads, and shielded PTO shafts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHands-Free Locking:\u003c\/strong\u003e Locks onto the Zerk and stays on, freeing up both hands to operate the grease gun.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Pressure Rated:\u003c\/strong\u003e Tested and rated for leak-free operation up to 10,000 PSI (690 Bar).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Release:\u003c\/strong\u003e Simply depress the thumb lever to release, even under high pressure—no more yanking or twisting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Fits all standard 1\/8\" NPT grease hoses and works with all SAE and Metric Zerk fittings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRebuildable Design:\u003c\/strong\u003e The world's only rebuildable coupler; includes a spare seal and jaw kit for a lifetime of use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Pressure\u003c\/td\u003e\n\u003ctd\u003e10,000 PSI (690 Bar)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003e1\/8\" NPT (Female)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReach Length\u003c\/td\u003e\n\u003ctd\u003e3.625 inches (92 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall Length\u003c\/td\u003e\n\u003ctd\u003e5 inches (127 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoupler Diameter\u003c\/td\u003e\n\u003ctd\u003e0.625 inches (16 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHardened Steel Jaws, Nitrile Rubber Seal\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 GC81042 Grease Coupler XL\u003c\/li\u003e\n\u003cli\u003e1 x Spare Rebuild Kit (Replacement Jaws \u0026amp; Seal)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCKNLUBE","offers":[{"title":"Default Title","offer_id":53640515027310,"sku":"GC81042","price":49.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0057\/0333\/6025\/files\/Untitled-2026-04-20T093626.869.jpg?v=1776652601","url":"https:\/\/wiselinetools.ca\/products\/locknlube-gc81042-locking-grease-gun-coupler-xl","provider":"Wise Line Tools","version":"1.0","type":"link"}
