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 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 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 I-IP Series is an extension of ISO A style couplings, popular worldwide for its versatile interchangeability. This ISO interchange coupler features a push pull mounting feature and a nipple with a modular port design that allows for a range of port options.
The VEPHD (Heavy Duty) Series offers the same features of the VEP series, with upgraded material, a yellow o-ring visual ID, and larger mating areas. Like the VEP, the VEPHD is a popular solution for hydraulic circuit applications subject to high pressure impulses and circuits which experience high residual or trapped pressure in a line, offered in a more durable, higher grade of steel and all QPQ plating for increased longevity.
