Features:	Safety sleeve lock prevents accidental disconnections. Non-Interchangeable design prevents crossing of lines. Color coded sleeves for easy identification: 600 green, 700 red. Designed for use with compressed air and other gases.
Applications & Markets:	Breathing Equipment Welding Shipyards General pneumatics Construction Nitrous Oxide
Materials:	Standard body material: Brass Standard seal material: Buna-N
Specifications:	Series 600 and 700 couplings with sleeve lock feature comply with OSHA requirements,* which state couplings shall be a type that cannot be unlockedor disconnected by means of straight pull without rotary motion. * 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:	Series 600 couplings are not to be used with oxygen at pressures exceeding 100 psig. 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 itonly within the specified service pressure range.
