International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Chemicals
To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings. They’re also known as flush-face and double shut-off couplings. A complete coupling consists of a plug and socket (both sold separately). They connect and disconnect quickly, so use them if you need to access a line frequently. Made of 316 stainless steel, they have excellent corrosion resistance and withstand a variety of chemicals.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects. These sockets have an internal fluoroelastomer gasket that resists a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.
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 Minimal-Spill
Quick-Disconnect Hose Couplings for Hydraulic Fluid
Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the International Standard ISO Minimal-Spill quick-disconnect plugs are compatible with any of the International Standard ISO Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. 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. They are zinc-plated steel, which has excellent strength and durability and fair corrosion resistance.
Plugs are also known as nipples.
Connect-under-pressure plugs have an internal reservoir, so they absorb up to 5,000 psi of residual pressure in the line. Use them when your hose is left in the sun and residual pressure cannot be safely released.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
NPTF (Dryseal) threads are compatible with NPT threads.
UN/UNF (SAE Straight) threads are also known as O-ring boss 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.

Pioneer 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 Pioneer quick-disconnect plugs are compatible with any of the Pioneer quick-disconnect sockets of the same coupling size, regardless of the pipe size. Plugs are compatible with Parker 4000, Parker 4200, SafeWay S20, and SafeWay S40 sockets. 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 and sockets are zinc-plated steel, which is strong and durable with fair corrosion resistance.
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.
Pioneer × ISO Minimal-Spill couplings let you adapt between different quick-disconnect styles. ISO Minimal-Spill quick-disconnect couplings are also known as ISO 16028 couplings.
Plugs and sockets with a gasket offer extra protection against leaks.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.

Hose Couplings for Hydraulic Jacks
Connect a hose to a ram or pump.
Quick Disconnect—High-pressure minimal spill couplings have a flat face, which ensures minimal fluid loss when connecting and disconnecting your hose line. They're double-shut-off style, so there is a valve in both the plug and the socket. To connect, push the plug into the socket until you hear a "click." To disconnect, slide the sleeve forward until the plug ejects.
