Grease Fittings
Thread these fittings into motors, bearings, engine blocks, and other machinery to create a lubrication point. They’re also known as hydraulic grease fittings.
Zinc-plated steel fittings have mild corrosion resistance.
Fittings with a check valve prevent grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.

Flush-Style Grease Fittings
The nipple doesn't stick out, so these fittings fit in tight spaces and won't be damaged if something knocks into them. An integral check valve prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
Zinc-plated steel fittings have mild corrosion resistance. Install Style C with a hex wrench.

Grease Fitting Adapters
When the size or thread type of a fitting doesn't match an existing opening, use these adapters to make the connection.
Intermittent swivel adapters rotate to make it easier to access your fitting in tight spaces.
Zinc-plated steel adapters have mild corrosion resistance. Brass adapters resist corrosion better than zinc-plated steel adapters. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.

Remote-Access Grease Fittings
Access difficult-to-reach lubrications points from up to 10 ft. away. These fittings are made of brass, so they resist corrosion. An integral check valve prevents grease from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants.
Cut the included tubing to your desired length before attaching fittings.

Oil Fittings
Zinc and zinc-plated steel fittings have mild corrosion resistance. Nickel-plated brass fittings are more corrosion resistant than zinc-plated brass fittings.
Fittings with a self-closing hinged cover block contaminants from entering equipment.
Note: Fittings do not hold oil; any oil dispensed into the fittings passes into the part to be lubricated.

Breather Vents
Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks. You can also use these breather vents to block debris from entering equipment.
Breather vents with splash guard are good for containers that are often filled and drained; they have a guard that prevents oil from splashing out of the vent hole.

Lockable Breather Vents with Cap
Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering. These breather vents allow you to add a filling port to your hydraulic tank while protecting against excess pressure and vacuum. Use them to stop debris from entering your tank. Breather vents mount on top of standard tank openings with included hardware. Padlock is not included.

Easy-Access Threaded On/Off Valves
Extend your reach in hard-to-access areas—turn these valves on and off using a square ratchet to grasp the hole at the end of the handle. They are full port, so they do not restrict flow.
316 stainless steel valves are more corrosion resistant than bronze valves.
Fix lockable lever handles in place using a padlock (not included).
Valves with a grease fitting have a built-in lubrication point. Inject lubricant for smooth operation and an extended service life. You can also remove the fitting to drain excess fluid from your valve.
