The VLS Series Heavy-Duty Screw Coupler is a durable product using heavy duty poppet style valves for the sealing mechanism and threads as the mechanical connection. The VLS series couplings feature a particularly rugged design, making them particularly well suited for heavy-duty service conditions, including construction equipment used in extreme off-highway conditions.
Screw-on system interchangeable with German market couplings
Internal components designed to reduce turbulence and handle impulse applications
Zinc plated steel coupling body with zinc plated hardened steel nipple
Nitrile seals and Teflon anti-extrusion rings
Available in two sizes: 1/2 and 1 inch
APPLICATIONS
Particularly well suited for heavy-duty service conditions
Off-highway applications, especially in construction equipment under extreme conditions
Wherever turbulence must be reduced and impulses must be managed

* Connect torque and disconnect torque without residual pressure. Torque will increase with residual pressure.
** Spillage is an indicative value of the fluid loss per couple-uncouple cycle without residual pressure.
The PPC Series (Push-Pull 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.
Protective caps and plugs are useful accessories that prevent damaging dust, water or mud from entering the quick couplings, thus lengthening their working lives. Repair kits are available upon request.
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.
The VOFX Series Threaded Poppet Couplers provide high resistance to pressure impulses and are manufactured with corrosion-resistant 316 stainless steel, in a compact design. Like the VOF, the internal parts of the VOFX 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.
