Holmbury / H Series

Description:

Flat Face Couplings H Series

Coupling Category

Flat Face Couplings

Manufacturer

Holmbury

Construction plant, mobile equipment, general industrial, nuclear, mining and agricultural. Applications involving dusty or dirty environments and where oil loss on disconnection cannot be tolerated.

ADVANTAGES
  • Flat mating faces are easily wiped clean to prevent the ingress of contaminants.
  • Improved flow path minimises the pressure drop.
  • Non-spill design avoids fluid loss during connection and disconnection.
  • No air intrusion during connection.
  • Locking sleeve prevents accidental disconnection.

STANDARDS
Conforms to ISO 16028 (2006) in all respects, i.e. dimensions and performance.

MATERIALS

Hardened carbon steel body, zinc plated, nitrile seals.

CONNECTION / DISCONNECTION UNDER PRESSURE

Connection with residual pressure in the line will be difficult or impossible.
For applications where connection under pressure is required, a Holmbury APM male coupling, or a screw coupling from either the HSC, VP or VEP ranges is recommended.
Disconnection of any quick disconnect / quick release coupling whilst under full system pressure can be very dangerous and should not be attempted.
