High pressure hydraulic screw coupling
1/4 - 3/8", 700 bar | HPA series
Holmbury High Pressure Ball Seal Screwed Couplings
can be connected and disconnected even with a low
residual hydraulic pressure in the line. The screw
connection mechanism eliminates Brinelling
(indentation of the locking balls into the retaining
groove) and thus makes the couplings suitable for high
pressures and pressure pulse applications. Two sizes
are offered, 1/4" and 3/8" NPT.
H Compatible with all high pressure pump and cylinder
manufacturers (Enerpac, SPX, Larzep and Hi-force)
H Connection and disconnection can be performed
even with low residual hydraulic pressure in the line.
H Screw thread retaining mechanism eliminates
