Flat Face Coupler products

flat face couplers

Specifically designed for applications needing no-leak performance. With mating faces that are easily cleaned before connecting, flat face couplers are the ideal solution for limiting contamination in a hydraulic circuit.

A Premier

The A Premier series flat face ISO 16028 interchange couplings offer higher pressure ratings, superior flow characteristics, and lower pressure drop compared to FIRG Series or competitors’ products. Specifically designed for applications needing no-leak performance and the ideal solution for limiting contamination in hydraulic circuit, the non-spill design avoids fluid loss in connection and disconnection.

Features
  • Size range: 1/8” thru 1 1/2”
  • Port options: NPT, SAE, JIC, ORFS, BSP, DIN
  • Interchanges with ISO 16028
  • Working pressure: 27-42 MPa/3915-6090 psi range
  • Lock system stops unwanted disconnect
  • Modular structure for multiple port option
  • Hardened steel, 12 to 20 balls reduce brinelling
Applications
  • Specifically designed for applications needing no-leak performance
  • Ideal for limiting contamination in hydraulic circuit
  • Applications involving high pressure impulses in agriculture equipment, mobile construction equipment, oil & gas exploration, and general industrial plants

FIRG

The FIRG flat face series, the original ISO 16028 interchangeable coupling, continues to offer good performance, long life and competitive pricing. The integrated sealing mechanism greatly reduces premature wear caused by movement between coupler and nipple parts affected by impulse pressure and the weight of the hoses and tubing when the coupling is in horizontal position.

Features
  • Size range: 1/4” thru 2”
  • Port options: NPT, BSP
  • Interchanges with ISO 16028
  • Working pressure: 20-30 MPa/2900-4350 psi range
  • Non-spill design avoids fluid loss during connection/disconnection
  • Minimal air inclusion during connection
  • Tight tolerances ensure equal loading of couplers
Applications
  • Anywhere fluid loss and hydraulic circuit contamination need to be reduced or eliminated
  • Mobile construction, agriculture, and mining operations
  • General industrial plants

APM

The APM series flat face couplings are state-of-the-art solutions for high residual pressure. They address residual pressure in a circuit anywhere thermal expansion of trapped fluid causes pressure to develop, and connect by hand with residual pressure, without releasing any fluid into the environment. The APM is intended to relieve pressure within itself only.

Features
  • Size range: 3/8” thru 1 1/2”
  • Port options: NPT, SAE, JIC, ORFS, BSP
  • Interchanges with ISO 16028
  • Relieves pressure within itself only
  • Connect/disconnect up to 30 MPa/4350 psi residual pressure
  • Connect under high pressure, by hand
  • Flat face design eliminates leakage and contamination in the circuit
  • Male body black zinc plated for identification
Applications
  • Mobile equipment and attachment tools, where sun exposure/temperature change causes pressure due to thermal expansion of trapped fluid
  • Any application where static pressure can get locked into the system

A-HD

The A-HD series flat face couplings address residual pressure in a circuit, anywhere thermal expansion of trapped fluid causes pressure to develop. They connect by hand with residual pressure, without releasing any fluid into the environment, due to an internal valving system.

Features
  • Size range: 3/8” thru 1/2”
  • Port options: NPT, SAE, JIC, ORFS, BSP
  • Interchanges with ISO 16028
  • Connect/disconnect up to 1595 psi residual pressure
  • Connect under pressure, by hand
  • Flat face design eliminates leakage and contamination in the circuit
  • Black ID ring
Applications
  • Mobile equipment and attachment tools, where sun exposure/temperature change causes pressure due to thermal expansion of trapped fluid
  • Any application where static pressure can get locked into the system

Push Pull

The PPC/push pull series coupler is built on the A Premier platform, featuring breakaway capabilities that engage when the coupler is unintentionally left coupled, preventing leakage and damage. Its clamp fixture is designed to be mounted to the structure; when pulled apart in line with the coupler, the PPC coupler will break away. For mobile applications: the APM series nipple is recommended with this series.

Features
  • Size range: 3/8” thru 3/4”
  • Port options: NPT, SAE
  • Interchanges with ISO 16028
  • Simple, easy-to-use push/pull connection
  • Breakaway design automatically disconnects in case of accidental disconnection of the hydraulic hose
  • Prevents leakage and damage
Applications
  • Refuse compactor/power units and dump trailer connections
  • Snow plow equipment
  • Agricultural implements

FIRGQ

The FIRGQ series flat face couplings utilizing QPQ plating technology for a corrosion resistant finish that is superior to zinc plating in many environments. It is a low-cost alternative to cost-prohibitive stainless steel applications and can be supplied with a variety of seals for fluid compatibility and operating temperature requirements.

Features
  • Size range: 1/4” thru 2”
  • Port options: NPT, SAE, BSP
  • Interchanges with ISO 16028
  • Working pressure: 20-30 MPa/2900-4350 psi range
  • QPQ plating treatment for corrosion resistant finish
  • Non-spill design avoids fluid loss during connection/disconnection
  • Minimal air inclusion during connection
Applications
  • Low and medium corrosion environments
  • Systems operating on mineral oil, steam, water or other low or medium corrosive fluids
  • Steel mills, various industrial process applications, tire manufacturing, state/municipal right-of-way spraying

FL

The FL series flat face couplings are designed with high corrosion resistance and excellent fatigue life. The FL couplings are manufactured in 316 stainless steel to eliminate leakage during connection/disconnection, reduce contamination in the circuit, and offer optimal resistance to corrosion. Standard seals are Viton/Fluorocarbon; other materials available for various fluids and operating temperatures.
