  Series 600 and 700 couplings with sleeve lock feature comply with O.S.H.A. requirements, Sec. 1915.35 (f)(5), 1916.35 (f)(5), 1917.35 (f)(5), and 1926.350 (f)(5).
  
  Warning: Oxygen increases combustibility. Fire and explosion could occur causing severe bodily injury or death. Be sure to select the proper coupling for your application and use it only within the specified service pressure range.

600 & 700 Series quick connect couplings are designed for use in oxyacetylene service. Series 600 is used with oxygen. Series 700 is used with acetylene.

Features:

• Ball lock
• Manual operation
• Non-interchangeable designs prevent crossing of lines
• Sleeves are color coded to identify each series:
  • Series 600 sleeves are green for oxygen
  • Series 700 sleeves are red for acetylene
• Series 600 and 700 couplings can also be used with compressed air and other gases
• Sockets with the SL suffix have the sleeve lock feature to prevent accidental disconnection

Flo-Temp couplings provide the flow needed to cool or heat injection molds and die casting dies. Sockets are available non-valved for maximum flow and valved to prevent fluid loss when disconnected. Flo-Temp couplings can be used with water-glycol, hot water and hot oil. Body sizes are 1/4", 3/8" and 1/2".

Features:

• Non-valved straight through models for maximum flow
• Valved sockets for automatic shut-off when line is disconnected
• Sockets available with straight, 90° or 45° hose stems or without hose stem
• Brass plugs with male pipe thread for recessed mounting to avoid damage to plugs when molds are being changed or stored

The Full-Bore Series is a premium automatic one-way shutoff coupling. Two sleeves must be actuated in sequence to bleed off back pressure and release the connector, preventing accidental uncoupling. Available in 3/8" and 1/2" capacities.

Features:

• Pressure relieving feature fully vents downstream air, making connection/disconnection fast and easy, and eliminating hose whip
• Unique straight-through design eliminates restrictive springs and poppet valves, allowing unimpeded air flow
• Two-sleeve activation prevents accidental disconnect

Gas-Mate couplings are one-way shut-off safety couplings designed for the connection of gas cooking appliances and other gas-fi red devices. Body sizes are 3/8", 1/2", 3/4", 1" and 1¼".

Features:

• Connect and disconnect without using wrenches
• Automatic shut-off when plug is removed from socket
• In case of fire, heat-sensitive plug allows socket valve to close, stopping gas flow
• Push-to-connect (1¼" only)

When fluid lines may be subjected to a damaging pull, couplings can be mounted to disconnect automatically, sealing both ends of a line against fluid loss. The socket sleeve can be anchored to a stationary bracket, either directly or with a chain.
Excessive pull on the plug end of the line moves the socket body forward relative to the sleeve, and the plug is released without damage to the line.
Release Clamp Assembly Kits are available for Series 1-HK through 8-HKP sockets.

The steam coupling has a large diameter flange on the sleeve to aid gripping while the user wears heavy gloves. EPDM seals are standard, and can be used with steam at temperatures up to 350°F.
Options are BSPP threads, sleeve lock, EPDM seals for use with steam at temperatures above 350°F and fluorocarbon seals.
