These polypropylene couplings are lighter in weight than metal cam-and-groove couplings, yet have the corrosion resistance to handle chemical applications. They have excellent strength and abrasion resistance. Couplings consist of a plug and a socket that are sold together as a set. Use them to quickly connect and disconnect medium-to large-diameter hose lines. Also known as dry disconnects and double shut-off couplings, the plug and the socket both have a shut-off valve for minimal fluid loss when disconnecting the hose line. To connect, insert the plug into the socket, press the locking levers down, and turn the valve handles to the open position. The locking levers prevent accidental disconnection. To disconnect, turn the valve handles to the closed position, lift both levers, and pull out the plug. Couplings cannot be disconnected when the valves are open. They are not compatible with any other style of coupling. Dust covers are included to protect the ends of couplings when not in use.

Note: The listed length refers to the length of the coupling when connected.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.

Push these connectors together to quickly create signal and data connections in tight spaces. They need less space to mate than screw-together connectors, which require two hands to twist them in place. However, screw-together connectors offer a more secure hold. These connectors have pin connections and a half-round or V-notched face for a snug fit that resists shock and vibration. Rated for over 2,000 mating cycles, the pins stand up to repeated connections and disconnections. Plugs can only mate with sockets of the same size, latch option, and pole count.

Connectors with a wire lead connection come with wire leads attached to save you time on installation.

Connectors with a built-in latch keep your mated connections secure.

Add latching clips to connectors without a built-in latch to secure your mated connections.

Empty fluid from tanks in boiler rooms or heat transfer systems—these valves withstand higher temperatures than our other drain valves. Also known as stop cocks, their handle twists open to let liquid flow out. They have a spout that smoothly pours the draining liquid into buckets without splashing. The handle is positioned to be out of the way from the spout, so your hand stays dry.

Plastic handles have a knurled grip that’s comfortable and won’t slip as you turn it. Aluminum handles are more durable than plastic handles.

PTFE seals create a tighter seal than brass and stainless steel seals.

These breather vents are rated NEMA 6 to withstand periodic submersion in water. Install them in enclosures to stop the buildup of pressure and vacuum and to prevent debris from entering equipment. Breather vents can be used with enclosures that are rated NEMA 4, 12, and 13 for washdown environments and splashing oil and coolant.

Vents with barbed connections fit unthreaded openings and are held in place by friction.

These gaskets are made of PTFE, which is chemically inert (except to molten alkali metal and elemental fluorine). Use them to seal gasket tube fittings for stainless steel tubing. They’re 3-A certified to meet industry approved sanitary design standards.
