Series HK Couplings are the most versatile couplings available and are suitable for use with various liquids, chemicals, steam, gases and vacuum. Series HK couplings conform to the dimensional requirements of ISO 7241-1 Series B. Body sizes range from 1/8" to 1".

Features:

  • The coupling that set the industry standard
  • Multiple options make the HK our most versatile coupling series available
  • Brass, steel and stainless steel construction available in all sizes; 1/4" body size is also available in polypropylene
  • End connections are female NPTF, BSPP and SAE o-ring boss
  • Heavy duty steel couplings for use in high impulse service available in most sizes
  • Steam coupling available in 3/8" body size


High Impulse – The high strength steel and heat treatment used to give increased resistance to “brinelling” (indentations by locking balls in the plug groove).
Hydraulic Coupling Sockets, Series 1 HK to 8 HK
Hydraulic Coupling (Socket+Plug), Series 1 HK to 8 HK
