Air-Powered Pistol-Grip Grease Guns

Use compressed air to dispense grease. This gun has a pistol grip that allows for one-hand operation, so it’s better for lubricating hard-to-reach spots than a lever-grip gun. Pull the trigger using small strokes to deliver small amounts of grease; hold the trigger for a continuous flow. The gun has a spring guard on the nozzle to prevent kinking.

Round Coupling Nuts

Less bulky than hex coupling nuts, these have a smooth, round body that fits in tight spots. Their finished appearance makes them a common choice for decorative applications. Tighten by hand, or use soft-jaw pliers to avoid marring the outside surface. Also known as extension nuts, they are commonly used to connect lengths of threaded rod and join threaded parts.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Oil Fittings

Note: Fittings do not hold oil; any oil dispensed into the fittings passes into the part to be lubricated.

Straight with Ball Check Valve

Fittings with a check valve prevent oil from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

UNEF Thread—UNEF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.

Battery-Powered Pistol-Grip Grease Guns

More portable than air-powered options, these guns operate on a rechargeable battery. They have a pistol grip that allows for one-hand operation, so they're better for lubricating hard-to-reach spots than lever-grip guns. To illuminate your lubrication point, they have a built-in light. Pull the trigger using small strokes to deliver small amounts of grease; hold the trigger for a continuous flow. All guns have a spring guard on the nozzle to prevent kinking.

12V DC Battery—12V DC guns require a filler nipple (sold separately) to load grease using a bulk filler pump.
