Take the struggle out of trying to grease recessed fittings on vehicles, fork lifts and farm equipment with the STEELMAN 06133 90-Degree Angle Push-Type Grease Gun Adapter. Attaching to any standard grease gun hose or extension via a zerk fitting on its end, this coupler lets you access recessed and right-angle mounted grease fittings inaccessible by regular straight couplers. The push-on type connector on the end slips easily over zerks and rely on hand pressure to keep a secure sealed on the fitting. The adapter's 4.25-inch length allows it to double as an extension to reach past obstructions to access deep set zerks. A locking sleeve on the base of the adapter helps secure it to existing push-on grease gun couplers. Backed by a lifetime limited warranty.
