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

** Spillage is an indicative value of the fluid loss per couple-uncouple cycle without residual pressure.
The BIR Series ISO A Interchange Couplers are one of the most popular designs worldwide, due to their durability and use of a poppet style valve for the sealing mechanism. The BIR series features a zinc plated steel coupler and zinc plated hardened steel nipple, with nitrile seals. They are available from size 1/4 to 2 inches in size, to cover the various fields of hydraulic applications.
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.
The One Position Series of Multi-Coupling Plates allows the simultaneous couple and uncouple of single large diameter hydraulic lines with a single, simple movement requiring very little force. The system reduces connection time and insures couplers are fully connected. The auto-locking system insures that lines are connected safely and provides secondary retention of the connection.
The DP Series of Multi-Coupling Plates allows the simultaneous couple and uncouple of two to four hydraulic and/or electrical lines with a single, simple movement requiring very little force. The circuit lines can all have the same coupler nominal diameter and different media. A dust cap is supplied, and options include: an electrical connector for low voltage requirements and a parking station.
