Holmbury Quick Release Couplings


Holmbury’s range of ISO.A Series Quick Release Couplings are available from stock here at Parker Hydraulics and Pneumatics Ltd on our same day despatch service throughout the United Kingdom. As an official Holmbury distributor, we are able to source and supply all of their products quickly and cheaply in comparison to our competitors.

ISO.A quick release couplings are perfectly suited for hydraulic and agricultural applications. A poppet valve is used to minimise the pressure drop characteristics and provide a positive sealing arrangement. Compared with ISO.B couplings, ISO.A are smaller and easier to connect and release.

Key Features:

  • Positive, quick connection ensured by the snap together locking ball system
  • When connected, the male and female halves can rotate, even under pressure, thus avoiding torsional stress in the flexible hoses
  • Designed to withstand high pressure peaks and pulses
  • Poppet valves have balanced springs and calibrated oil flow passages to minimise the pressure drop
  • Poppet valve seals have shockproof protective edges

Material: Zinc plated, heat treated carbon steel. Nitrile ‘O’ ring seals are fitted as standard. VITON seals are available on request.
