The XL model combines a patented locking jaw with a longer steel neck, a one-hand thumb release and a rebuildable internals design. It fits most grease guns and is rated to 10,000 PSI for shop, fleet, agricultural and industrial use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the LockNLube XL stay connected to the fitting?\u003c\/h3\u003e\n\u003cp\u003eThe coupler uses patented locking jaws that clamp firmly around standard Zerk fittings so the connection won’t detach under pressure.
