Request Information

Series ST straight through couplings are designed for use where minimum pressure drop is required and valving is not needed. They are well suited for use on pressure wash, steam and carpet cleaning equipment, and many fluid transfer systems. Body sizes range from 1/8" to 2½".

Features:

  • Ball lock
  • Manual operation
  • Smooth bore permits free flow of liquid or gas
  • Male and female NPTF, BSPP and hose stem connections
    • Unit of Measure

    • 2 Pressure ratings are for sockets and plugs with threaded end connections. Pressure ratings of couplings with hose stems may be signifi cantly lower, and will depend on the type of hose and the method of clamping. Refer to hose manufacturer’s end connection pressure ratings. The best way to determine suitability for an application is to run pressure testing under controlled conditions.
