Description:
FIRG SERIES / Premier Range
Coupling Category
Flat Face Couplings
Manufacturer
Holmbury
Where clean connections are required despite dusty or dirty conditions. 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.

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.
ANTI-BRINELLING FEATURES
- 12 ball locking mechanism in the 1/4", 3/8", 1/2", 1/2"A, 1" and 11/4" couplings.
- 15 ball locking mechanism in 3/4" and 3/4" B couplings.
- 18 and 20 balls in the 11/2" and 2" couplings respectively.
- Close tolerance male and female mating diameters to ensure equal ball loading.
ADVANTAGES
- Flat mating faces are easily wiped clean to prevent the ingress of contaminants.
- Streamlined internal flow path minimises the pressure drop.
- Non-spill design avoids fluid loss during connection and disconnection.
- No air intrusion during connection.
- Locking sleeve prevents accidental disconnection.
- Bi-directional flow.
- Sizes 3/8" and 1/2" comply with HTMA interface requirements and are recommended by the BHTMA for use in equipment manufactured by its members.
- Conforms to current ISO 16028 Standard sizes. PREMIER FEATURES
- Robust construction. High working and burst pressure ratings. Excellent fatigue life.
- Female coupling seal swaged-in to prevent extrusion under pressure.
- Dynamic seal geometry in male couplings allows bi-directional flow.
