HYDRAULIC QUICK RELEASE COUPLINGS
Connect or disconnect hydraulic lines quickly & easily without the use of tools. Quick Release couplings (QRC) also known as, Quick connect couplings are used to provide a fast, make-or-break connection of hydraulic fluid transfer lines. The HQ Series flat face couplings are known globally for their leak free performance in high pressure pulse, hammer circuits and many other applications. Preferred choice for many global OEMs.
ISO A couplings are the ideal choice where a tough, durable product of superior quality is required. They are perfectly suited to agricultural and industrial applications. Distag offers a wide range of market-leading couplings from Holmbury and other suppliers.

MAKE-OR-BREAK CONNECTIONS
Used to provide a fast, make-or-break connection of hydraulic fluid transfer lines.
LEAK FREE
Known globally for their leak free performance in high-pressure pulse, hammer circuits & many other applications.
PERFECTLY SUITED
Perfectly suited to agricultural & industrial applications.
IA, IAZ & IAS SERIES
ISO A – QUICK RELEASE COUPLING
Our IA Series ISO A couplings are the ideal choice where a tough, durable product of superior quality is required. They are perfectly suited to agricultural and industrial applications.
IAP – CONNECT UNDER PRESSURE
IAP SERIES- CONNECTS TO 1/2” ISO MALE PROBES
Our IAP Series ISO A female couplings are designed primarily for the agricultural industries and incorporate a push-pull design. The coupling can be either panel mounted using circlip grooves or manifold mounted.
IAPC – CONNECT UNDER PRESSURE ISO-A
IAPC SERIES
Our IAPC Series ISO A couplings incorporate a pressure relief mechanism that enables them to be connected under pressure by hand.
P SERIES – PUSH PULL FEMALE COUPLING
CONNECTS TO 1/2”ISO MALE PROBES
P Series ISO A female couplings are designed primarily for the agricultural industries and incorporate a push-pull design. The coupling is panel mounted using circlip grooves in the locking sleeve.
F SERIES (NORDIC) – HIGH FLOW COUPLING
CONNECTS TO 1/2”ISO MALE PROBES
Our F Series high flow safety couplings offer three important benefits; high flow, connection under pressure and a safety locking mechanism to prevent accidental disconnection.
TB SERIES – TRAILER BRAKE COUPLING
ISO 5676 STANDARD
Our TB Series trailer brake couplings are used to connect the hydraulic braking system of tractors to trailers. The male coupling is normally panel mounted on the tractor.
HQ SERIES – FLAT FACE COUPLINGS
ISO 16028 STANDARD
Our HQ/HQ90 Series flat face couplings (Holmbury’s flagship products), known globally for their leak-free performance in high-pressure pulse, hammer circuits and many other applications. A preferred choice for many global OEMs.
HQ90 SERIES – 90° FLAT FACE COUPLINGS
ISO 16028 STANDARD
H90 Series is designed for use in applications that require a 90° elbow in the hydraulic circuit, such as digger booms. The right-angle design allows for easy mounting without the need for additional fittings, reducing potential leakage paths and cost.
HCP SERIES – FLAT FACE CONNECT UNDER PRESSURE
ISO 16028 STANDARD
HCP Series male couplings are designed to connect under pressure by hand with up to 350 bar locked in the male half, making it an ideal choice for applications where the ability to connect under pressure is essential. The HCP Series also benefits from all the key features of the HQ Series flat face couplings.
MP SERIES – MULTIPLATE CONNECTOR
CONNECTS TO 1/2″ ISO MALE PROBES
MP Series multiplate couplings allow the simultaneous connection of multiple hydraulic lines. The MP Series inherits the benefits of Holmbury’s flat face coupling design. Currently available with 2, 4 or 6 port design.
HFT SERIES – SCREW TO CONNECT
CONNECTS TO 1/2″ ISO MALE PROBES
Our HFT Series screw connects couplings incorporate all of the benefits from the flat face design, whilst the screw connection strengthens the coupling and eliminates brinelling. Connection and disconnection can be undertaken with high residual pressure in male coupling. The HFT Series is an ideal solution for high-pressure pulses and many other applications.
ROTARY COUPLINGS – IN-LINE
GGIL SERIES
Our GGIL Series in-line rotary couplings are designed for in-line use on hydraulic circuits. Using a rotary coupling in the hydraulic line stops the hose twisting, limiting stress and increasing hose lifespan.
ROTARY COUPLINGS 90º
GG90 SERIES
Our GG90 Series 90 degree rotary couplings are designed for use on hydraulics lines that may be subject to torsional stress to allow rotation of hydraulic pipes and hoses. Using a rotary coupling in the hydraulic line stops the hose twisting, limiting stress and increasing hose lifespan.
PWC SERIES – PRESSURE WASHER COUPLINGS
FREE FLOW, VALVELESS PRESSURE WASHER
Pressure washer couplings can accommodate high flow rates with minimal pressure drops. The female coupling has a double O’ring sealing arrangement. Valve-less design means that product may be lost during disconnection and so suitable only for non-hazardous media.
HYDRAULIC GRIP HANDLES
FITTING & REMOVING OF HYDRAULIC SERVICE HOSE
Hydraulic Grip for easy fitting and removal of hydraulic service hoses. This kit is to fit standard 1/2″ BSP thread male probe couplings and suitable for hoses up to 1/2″ BSP inside size.

As a leading supplier of complete port-to-port solutions, at Distag QCS Group we offer a comprehensive range of fluid power components, including tube connection systems, hydraulic hose, fittings, assemblies, kits, motors, cylinders, valves, and accessories. The range includes FLEXEPULSE hose, FLEXEQUIP and VOSS tube and end-fittings.
Celebrating 50 years in Hydraulics
Distag QCS (UK) Ltd, previously known as Flexequip Ltd, was founded in July 1971 and began manufacturing hydraulic couplings to service a large home and export market across the world through a distribution network.
The Flexequip brand has been synonymous with designing and manufacturing high-quality hydraulic couplings for over 50 years. From the early days of re-usable couplings, and braised adapters, to the current range of one & two-piece fittings, the FH logo is widely recognised across Europe, UK, and the Middle East.
Following the acquisition by the Distag group in 2006, the company has continued to expand the product range and service provided, and today we carry over 10,000 active hydraulic component SKUs, including hose, fittings, adapters, QR couplings, valves, motors, cylinders, clamps & hose protection.
In addition to the components provided, Distag also manufacture hose assemblies, manipulated steel tube assemblies, and build hydraulic kits according to customer specification.
While the name may have changed, and the product range expanded, we are proud to have some members of the team still with us today, who have been on this journey with the company for over 30 and 40 years; and witnessed the continuous development and improvement in hydraulic couplings.
We welcome you to take a look at our new celebration catalogue, and see some of the products which will take us into next 50 years phase.
