The VOF Series Threaded Poppet Couplers provide high resistance to pressure impulses, in a compact design. The VOF’s internal parts are designed to reduce turbulence and pressure drop, and its poppet valve with elastomer seal provides maximum sealing of the couplings when disconnected. A wrench flat on the bodies facilitates the fitting assembly, and the retainer is high resistance carbon steel.
Connection under residual pressure is allowed in one side
Positive-stop valving prevents flow checking
Large diameter steel sleeves resist deformation for maximum life
Inspection hole to visually confirm complete connection
APPLICATIONS

Protective caps, which can increase the product life, are always recommended to protect the couplings from damage and dirt. This is particularly important in oil & gas and mobile applications, where exposure to weather and aggregate materials are common. The protective caps for VOF couplings are manufactured in aluminum (natural color).
The Agriculture IR Series Hydraulic Quick Couplings offer automatic shut-off during disconnection. The IR features a variety of connection mechanisms: ball (IR), poppet (IRV), push pull (IRS) or push pull sleeve connectable under residual pressure (IRS PC). Poppet or flat-face are recommended for new applications.
The GR Series of Multi-Coupling Plates allows the simultaneous couple and uncouple of two to ten hydraulic and/or electrical lines with a single, simple movement requiring very little force. The circuit lines can all have the same nominal coupler diameter and different media or different size couplers. A dust cap is supplied, and options include: an electrical connector for low voltage requirements and a parking station.
The IRC Series Interchange Coupler, commonly referred to as a Nordic interchange, offers a safety sleeve to prevent accidental disconnection and a poppet valve with elastomer seal to provide maximum sealing of the couplings once disconnected. Standard poppet and pressure eliminator poppet available. Connection under residual pressure is allowed in male or female; counterpart side should be without pressure.
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.
