    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.

    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.
    Splash Guard—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.

    Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing. The seal expands to temporarily close off pipe openings.
    Style A—For Style A, twist the wing nut to expand the seal. They have an NPS threaded bypass for routing moderately pressurized fluids.
    Style B—For Style B, twist the wing nut to expand the seal. They have an NPS threaded bypass for routing moderately pressurized fluids.
    Style C—For Style C, twist the wing nut to expand the seal. They have an NPT threaded bypass for making leak-tight connections.
    Style D—For Style D, twist the wing nut to expand the seal. They have an NPT threaded bypass for making leak-tight connections.
    Style E—For Style E, twist the wing nut to expand the seal. They have a barbed bypass for quick connections to tubing.
    Style F—For Style F, twist the easy-grip T-handle to expand the seal. They have a barbed bypass for quick connections to tubing.
    Style G—For Style G, twist the easy-grip T-handle to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.
    Style H—For Style H, twist the wing nut to expand the seal. They have a bypass with BSPP threads, also known as G threads, for making leak-tight connections.
    Style J—For Style J, twist the wing nut to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.
    Style K—For Style K, twist the wing nut to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.
    Style L—For Style L, twist the wing nut to expand the seal. They have a GHT bypass that connects to standard garden hoses. Ideal for pipe cleanout, they allow for easy, controlled drainage.
    Maximum Air Back Pressure—Maximum air back pressure is the amount of pressure a plug can withstand without moving.
    Maximum Water Back Pressure—Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

    Air-Inflatable Plugs with Bypass

    Conform to wide and out-of-round pipes with these inflatable plugs. Also known as pneumatic plugs, they're designed for temporary seals since they can lose pressure over time. Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing.
    Inflate with a hand pump (sold separately); an air compressor may overinflate the plug and cause damage. Tether the plugs using either the eyebolt or chain/ring so they don't get lost or stuck in your pipes during installation. Pull on the tether for quick and easy removal once testing is complete.

    Self-Draining Breather Vents

    Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
