Air- and Water-Inflatable Plugs
Penetrate tight pipe junctures with the most flexible expansion plugs we offer. To inflate with air, use a hand pump (sold separately). Whether you fill with air or water, a pressure relief valve will prevent over expanding. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

Air- and Water-Inflatable Plugs for Wye-Joints
These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line. To inflate with air, use a hand pump (sold separately). Whether you fill with air or water, a pressure relief valve will prevent over expanding. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

Drain Valves
Also known as stop cocks, install these valves on your tank for easy draining of air or fluid.
Inline handles can be operated from any position. The handle surrounds the drain outlet, so liquids may splash onto your hands or the handle. Side handles are out of the way of the flow, so your hand and the handle stay dry.
Valves with an external seal are for higher flow applications than valves with an internal seal. They also have a longer valve stem, so they’re less likely to introduce contaminants from exposed threads. Valves with an internal seal have shorter stems than those with external seals, so they fit shorter clearances. However, they’re more likely to introduce contaminants to the tank from debris collected on the exposed threads.
Valves with a brass body won’t corrode when venting air or draining water—even in wet or humid environments.
Brass handles won’t corrode.
Valves with a thumb-screw handle open by rolling the slip-resistant thumb screw between your fingers. Since these valves don’t have a wide handle, they fit in tighter spaces than valves with other handle styles.

Valves with a wing-nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face inward, so they have a lower profile than handles with outlet-facing wing nuts.

Valves with a wing-nut handle give you leverage to open tight, stubborn valves that have been sealed for long periods of time. The wings on these handles face outward, so they fit tanks without enough clearance around the drain hole to fit handles with inlet-facing wings.

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.
Brass breather vents have good corrosion resistance.
