The Holmbury HQ Series flat face couplings are renowned for their exceptional performance and reliability across diverse hydraulic applications. Engineered in compliance with the ISO 16028 standard, these couplings are the preferred choice for numerous global Original Equipment Manufacturers (OEMs).

Key Features:

• Leak-Free Performance: Designed to prevent fluid loss during disconnection, ensuring a clean and efficient operation.

• Contamination Control: The flat face design facilitates easy cleaning, minimizing the inclusion of air and contaminants during connection.

• Safety Locking Mechanism: Equipped with a safety locking sleeve as standard to prevent accidental disconnection, enhancing operational safety.

• Bidirectional Flow: Supports fluid flow in both directions, offering versatility in system design.

Construction:

• Robust Materials: Constructed from carbon steel with a zinc-nickel plating, providing exceptional corrosion resistance—withstanding up to 1,200 hours without red rust in salt spray tests.

• Seal Options: Fitted with Nitrile Butadiene Rubber (NBR) seals as standard, suitable for operating temperatures from -40°C (-40°F) to 106°C (223°F). Fluoroelastomer (Viton®) seals are available for higher temperature applications, accommodating ranges from -20°C (-4°F) to 200°C (392°F).

Applications:

• Ideal for high-pressure pulse applications requiring leak-free performance.

• Widely used in construction equipment, mobile machinery, general industrial systems, agricultural machinery, and skid steer loaders.
