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 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 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 Wing Style Series Rugged Wing Nut provides reliable service wherever a coupling is required to connect under pressure with minimum spillage and air inclusion.
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.
