Rings for Claw-Clamp and Bolt-Together
High-Vacuum Fittings for Stainless Steel Tubing
- For Use With: Air
- Max. Temperature: 400° F
- Tubing: Use with 304/304L Stainless Steel or 316/316L Stainless Steel
Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings. They contain a Viton® fluoroelastomer O-ring—when you clamp or bolt your fittings together, the O-ring compresses to establish the seal.

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.
Plugs are also known as nipples.
Plugs and sockets with a gasket offer extra protection against leaks.
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.
