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
• Series 600 and 700 couplings with sleeve lock feature comply with OSHA requirements (29 CFR 1915.55 (f)(5), 1917.152 (d)(3)(iv) and 29 CFR 1926.350 (f)(5)), which state couplings shall be the type that cannot be unlocked or disconnected by means of a straight pull without rotary motion.
  
  To add a third non-interchangeable line, use the 100 Series with the 600 and 700 Series.
  
  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.
