What are hydraulic quick couplers

Hydraulic quick couplings allow the connection and disconnection of fluid lines in a fast and convenient way, without loss of fluid. They provide the users the ability to rapidly connect and disconnect hydraulic hoses to machines or attachments. Hydraulic quick couplings are precisely engineered for specific fluid applications and consist of two parts (male and female). When connected properly, these two counterparts ensure a perfect sealing, allowing the fluid to flow.

Types of hydraulic quick couplers

According to the needs, there are different types of products.

Stand-alone Hydraulic Quick Couplers

In order to connect a hydraulic line, the two halves of a single coupling must necessarily get coupled. The connection between the two parts can be done in many ways, depending on the design of the product: push to connect, screw to connect, sleeve retraction, push-pull. Another main feature that distinguishes the hydraulic quick Couplers is the valve type: ball, poppet or flat-face. Free flow passage (without valves) is another available option – although not too frequent.

Poppet quick coupling

The poppet valve is the most basic shut-off system that ensures high mechanical resistance, high sealing reliability and low risk of seal extrusion.

Poppet valves of Faster feature a special seal that ensures best resistance to flow and flow reverse, and loss of pressure is minimal compared to other products available. Poppet valve couplings are usually mounted agricultural machinery, oil tools and other hydraulic applications. A large group of Faster products are equipped with poppet valve: NV, one of the most popular Faster proprietary series, HNV, ANV, AGRI, OGV, VVS and many others

Flat face hydraulic couplers

The Flat Face design guarantees zero spillage and helps avoiding external contamination and air inclusion. The flat valve allows to connect hydraulic lines with no fluid loss, during both connection and disconnection maneuvers. Therefore, flat face couplings are considered good for the environment. Moreover, the flat surface makes them easier to clean and less disposed towards contamination and dirt. Under this family of couplings, Faster also offers the sector latching system enables to effectively tackle the Brinelling effect, provoked by high frequency impulse pressures. Flat face hydraulic couplers are often used in Construction Equipment and Forestry applications.

Threaded flat face couplers

Screw to connect couplings, also known as “threaded flat face couplers”, are specifically designed to resist bending effect, eliminating premature wear. The Flat Face valve brings same benefits mentioned above. Screw to connect flat face couplers are suitable for construction equipment and heavy-duty applications.

Multi couplings connection system

Multi couplings connection allows to simultaneously connect multiple lines with an effortless maneuver by means of a lever, even with residual pressure in the system. These multi connections can also be equipped with electrical connectors. A piece of equipment with several hydraulic lines can lead to a higher risk of a wrong connection; thanks to the MultiFaster technology the operator can easily connect and disconnect the attachment using an ergonomic lever. The plate layout makes wrong connections impossible. Moreover, the flat-face quick couplings integrated in the plate prevent spillage and help avoiding contamination.

Today, Faster is a primary force for research, design, and production of hydraulic quick release couplings.
