Holmbury / VEP Series Screwed Couplings
Description:
VEP Series Screwed Couplings
Coupling Category
Flat Face Couplings
Manufacturer
Holmbury
Hand held and excavator mounted breakers, shears and all systems subject to high pressure pulses.
Any system where connection or disconnection under pressure is required.
All systems where the security of a screw connector is needed.
INTRODUCTION
Holmbury VEP Series Screwed Couplings are ideal for systems subjected to high pressure pulses since they are immune to Brinelling.
ADVANTAGES
SPECIFICATION
Operating temperature range: -20°C to +100°C Fluid loss during disconnection: zero to 0.02ml Materials: QPQ hardened carbon steel body, other external parts zinc plated. PTFE and nitrile seals.
CONNECTION
When connecting the two halves, ensure the sleeve on the female butts up against the shoulder of the male. Nip tight with spanners to avoid the risk of unscrewing during use. If torsional forces will be exerted on the hoses, use a Holmbury GGIL rotary coupling.

INTRODUCTION
Holmbury VEP Series Screwed Couplings are ideal for systems subjected to high pressure pulses since they are immune to Brinelling.
ADVANTAGES
- Connect and disconnect under pressure
- Screw thread connection eliminates Brinelling
- Flat faces easily wiped clean to prevent ingress of contaminants
- Non-spill design avoids fluid loss during connection and disconnection
- Bi-directional flow with low pressure drop
