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.

Compact Pressure-Relief Valves
Due to their small size, these valves are often installed on tanks in low-clearance areas. They begin opening at the set pressure. Nylon valves fully open at about 10% over the set pressure and steel valves fully open at about 50% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. All have a vent outlet to exhaust discharge directly. Set pressure is not adjustable.
