Built from zinc-coated alloy steel with reinforced jaws and a durable sealing gasket, the Saker coupler prevents leakage at extreme pressure. Its unique retract mechanism helps you engage hard-to-see zerks while freeing one hand to control the grease gun.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the coupler keep grease from leaking under high pressure?\u003c\/h3\u003e\n\u003cp\u003eThe coupler uses reinforced jaws together with a premium sealing gasket to maintain a tight connection even at very high pressures. The patented locking design compresses the seal uniformly around the fitting to minimize blowback and mess.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eExclusive patented locking and sealing system\u003c\/li\u003e\n  \u003cli\u003eDurable sealing gasket engineered for extreme pressures\u003c\/li\u003e\n  \u003cli\u003eReinforced jaws for consistent grip on fittings\u003c\/li\u003e\n  \u003cli\u003eRated to perform at up to 14,000 PSI\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I operate this coupler with one hand and reach blind or awkward zerks?\u003c\/h3\u003e\n\u003cp\u003eYes — the Saker coupler’s smooth retraction mechanism enables true one-handed operation.
