HFT Series, Screw Couplings have been developed Hand held and excavator mounted breakers, shears, augers, trenchers and all systems subject to high pressure pulses. Any system where connection needs to be made with up to 350 bar residual pressure. All systems where the security of a screw connector is needed. Plant and equipment where non-spill disconnection is essential.

Advantages :

• Higher flow and lower pressure drop
• Zinc nickel surface finish rated for 1200 hours to white rust in salt spray tests.
• Screw thread connection eliminates Brinelling.
• Sleeve on female can be pushed back for access to the mating face.
• Flat mating faces of both the male and female are easily wiped clean to prevent the ingress of contaminants.
• Non-spill design avoids fluid loss during connection and disconnection.
• Connect with up 350 bar residual pressure in the line.

Tipper Couplings use a screw thread connection. The female coupling has a wing nut sleeve which enables operators to connect the couplings by hand, even when there is low residual pressure in the line. Tipper Couplings are designed for use on mobile plant such as commercial vehicle trailers, agricultural equipment and construction plant.

Rotary Couplings are used to protect hydraulic lines that are subjected to torsional forces or rotational motion. The spindle is carried on a roller bearing and has a low friction shaft seal that can rotate at maximum pressure with low torque.

IA Series, ISO.A 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.

Advantages :

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

HQ Series couplings are designed for use in excavatorhammer circuits and other applications involving high pressure pulses. Construction plant, mobile equipment, general industrial, nuclear, mining and agricultural.

Advantages :

• Flat mating faces are easily wiped clean to prevent the ingress of contaminants
• Improved flow path minimize the pressure drop
• Non-spill design avoids fluid loss during connection and disconnection
• No air intrusion during connection
• Locking sleeve prevents accidental disconnection
• Zinc nickel surface treatment eliminates chrome 6 and exceeds 200 hour salt spray tests to white rust

HP Series one of the most important benefits of these couplings is no fluid spillage on disconnection. The high pressure ratings of these couplings make them ideal for use with high pressure hydraulic tools, particularly when zero fluid loss is important.

HP series is suitable for High pressure plant and equipment operating with mineral oil. Rail industries, torque wrenches and many other industrial high pressure tools.

Advantages :

• Flat faces can easily be wiped clean before connection to prevent the ingress of contaminants into the circuit
• Clean disconnection - non-spill design
• No air intrusion during connection
• Locking sleeve prevents accidental disconnection
• Bi-directional flow

Holmbury HSS Series Stainless Steel Couplings have a high resistance to corrosion and are suitable for use with many fluids which include: acids, gas, and demineralized water. They are the ideal choicefor many industries such as marine, food, gas, chemical and pharmaceutical.
