ISO.A SERIES - PULL BREAK - HYDRAULIC COUPLINGS
¼" - 2" Poppet Valve Types to ISO 7241 Series A
INTRODUCTION
Holmbury ISO.A Series couplings are the ideal choice where a tough, durable product of superior quality is required. They are perfectly suited to industrial and agricultural applications. A poppet valve is used to minimise the pressure drop characteristics and provide a positive sealing arrangement.
COMPARISONS
In comparison to ISO.B couplings the ISO.A Series are:
CONSTRUCTION
Zinc plated, heat treated carbon steel. Nitrile 'O' ring seals are fitted as standard. VITON seals are available on request.

INTRODUCTION
Holmbury ISO.A Series couplings are the ideal choice where a tough, durable product of superior quality is required. They are perfectly suited to industrial and agricultural applications. A poppet valve is used to minimise the pressure drop characteristics and provide a positive sealing arrangement.
COMPARISONS
In comparison to ISO.B couplings the ISO.A Series are:
- Smaller.
- Easier to connect and release.
- 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 any 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.
