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.

Oil Fittings
Zinc and zinc-plated steel fittings have mild corrosion resistance. Zinc-plated brass fittings have good corrosion resistance. Nickel-plated brass fittings are more corrosion resistant than zinc-plated brass fittings.
Fitting with a check valve prevents oil from leaking when pressure causes backward flow. The valve stays closed when not in use to keep out dirt and other contaminants. Fittings with a self-closing hinged cover block contaminants from entering equipment.
UNF and UNEF threads are similar to threads on a machine screw or bolt. They require a sealant, such as an O-ring, to minimize leakage.
Note: Fittings do not hold oil; any oil dispensed into the fittings passes into the part to be lubricated.

Diesel Fuel Tank Caps
Often used with trailers, compressors, and other equipment tanks, these caps meet Department of Transportation requirements. Caps have fusible plugs that will melt when the outside environment reaches their opening temperature.
Cap with vent will automatically open when the internal pressure reaches between 6.5 psi to 8.5 psi to relieve pressure.
Oil Cups
A built-in reservoir allows oil to gradually pass through to equipment, reducing time spent on manual lubrication. Flow rate depends on temperature.
Use 90° elbow cups for side-mount applications and where vertical space is limited.
Oil cups with wick feed have a wick that extends through the threaded connection of the cup and keeps the bearing dust-free and lubricated, even after the oil cup is drained.
