About On/Off Valves

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.
PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads.

Button-Head Grease Fittings
Often used on earth movers, mining equipment, and other heavy machinery, these fittings have a T-shaped top that holds the dispensing tip in place so it won’t pop off when adding grease. They're best for machinery requiring high volumes of grease because they let more grease pass through than standard grease fittings, thanks to a larger opening. 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.

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. 303 stainless steel adapters are more corrosion resistant than brass adapters and have good chemical resistance.
PTF-SAE and NPTF (Dryseal) threads are compatible with NPT threads. UNF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage. SAE-LT threads are tapered but designed to be installed into a 1/4"-28 straight-thread UNF hole.

Grease Fitting Junction Blocks
Choose these blocks if you need to lubricate multiple points but need to control how each is greased. Unlike grease fitting manifolds, these blocks have multiple fittings, so you control what each point receives and when. Use the compression fittings on the outlets to connect tubing (not included) between the grease fittings and lubrication points.
Magnetic-mount blocks stick to machines and other steel surfaces.
Zinc-plated steel blocks have mild corrosion resistance. 303 stainless steel blocks are more corrosion resistant than zinc-plated steel blocks and have good chemical resistance.

Grease Fitting Manifolds
Save time by sending grease from one fitting to multiple points. These manifolds come with everything you need to set up a remote lubrication system. They deliver the same amount of grease to each lubrication point, so you’ll sometimes see them used to grease an entire machine. All lubrication points connected to the manifold must use the same type of grease.
The tubing attaches to the compression fittings on the manifold’s outlets. To connect the other end of the tubing to your lubrication point, use a compression fitting, an adapter, or both. Adapters come in a variety of shapes and sizes to reach tight or hard-to-reach areas.

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.

Grease-Dispensing Monitors
Extend the life of bearings by using these monitors to take the guesswork out of lubrication. Their sensor captures the ultrasonic vibration of grease as it fills your bearing and converts it into sound you can hear. As your bearing draws in the grease, the sound becomes quieter. Even in loud machine shops, you'll be able to track this sound with the noise-cancelling headphones and noise level readings shown on the monitor's screen. When the noise level stops decreasing, the bearing can't absorb any more grease and you should stop pumping grease to avoid over-lubricating your bearing.
The handset guides you through the steps for setting the noise level before applying grease. Use either the curved or flat magnetic mount to attach the sensor to the bearing. The monitor mounts to your grease gun, so you’ll have your hands free for pumping grease.

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.
