Holmbury / HPA Series
Coupling Type: Hydraulic Couplings & Adapters
High Pressure Ball Seal Screwed Couplings
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.
- Compatible with all high pressure pump and cylinder manufacturers (Enerpac, SPX, Larzep and Hi-force)
- Connection and disconnection can be performed even with low residual hydraulic pressure in the line.
- Screw thread retaining mechanism eliminates Brinelling
General industrial equipment
Zinc plated carbon steel body material with nitrile seals and PTFE backing ring. Other seal materials available on request.
Maximum working pressure for both sizes of couplings is 700 bar. Working temperature range with nitrile seals is -20°C to +100°C.
