International Standard ISO B Quick-Disconnect
Hose Couplings for Hydraulic Fluid
A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a hydraulic hose line. All of the International Standard ISO B quick-disconnect plugs are compatible with any of the International Standard ISO B quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings meet ISO 7241-1 Series B dimensional and performance standards and are compatible with Parker 60 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated.
Plugs are also known as nipples.
Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.
Push-to-connect sockets are easier to connect than sleeve-lock sockets. Connect by pushing the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
Zinc-plated steel is stronger and more durable than other metals. It has fair corrosion resistance. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. 303 stainless steel offers better corrosion resistance than zinc-plated steel and brass. 316 stainless steel provides the best corrosion resistance of all the metals we offer.
NPTF (Dryseal) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

International Standard ISO B Quick-Disconnect
Hose Couplings for Food and Beverage
Couplings are made of FDA listed materials, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All of the International Standard ISO B quick-disconnect plugs are compatible with any of the International Standard ISO B quick-disconnect sockets of the same coupling size, regardless of the pipe size. They are compatible with ISO 7241-1 Series B and Parker 60 couplings. Also known as double shut-off couplings, the plug and the socket both have a shut-off valve that stops the flow when the coupling is separated, so product won’t leak from the line. Plugs and sockets are acetal for excellent corrosion and moisture resistance, so they won’t absorb water and lose strength, even in high-humidity environments.
Plugs are also known as nipples.
Sockets are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings reflect static (constant) pressure conditions.
