Hydraulic Coupling Sockets, Series 1-HK to 8-HK
Promotions
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).
