Holmbury FIRG Series couplings were first introduced in 1982. Their early success was due to good performance, long life and competitive prices. As a result of their ongoing development programme, the couplings have over the years maintained a superb track record.
In 1992 a major upgrade was introduced and the name Premier Range added to reflect the dominant position of the FIRG Series couplings in the market. In terms of flow rate and pressure drop characteristics, the FIRG Series has now been eclipsed by the Holmbury 'A' Series Premier Plus Range. However, for many applications the FIRG Series still offers the optimum balance between price and performance.

The ISO IDIS 16028 Standard is based on the FIRG Series, since it's the most widely used type of flat face coupling with a proven track record.

APPLICATIONS

Where clean connections are required despite dusty or dirty conditions. The anti-brinelling features enable them to operate successfully in the applications involving high-pressure pulses.

User industries include: agriculture, construction plant, mobile equipment, general industrial, nuclear and mining.

OPERATION

To couple, wipe the mating faces clean and push the two halves together until they click shut. Twist the sleeve and the coupling is locked. To release, align the notched sleeve with the ball, pull back the sleeve and the coupling springs apart.

Holmbury Premier Plus ‘A’ Series flat face quick release hydraulic couplings provide a superior alternative to the standard Premier ‘FIRG’ Series.

In comparison, Premier Plus ‘A’ Series have higher pressure and flow ratings as well as lower pressure drops and greater resistance to Brinelling.
