The "W" Series couplings with their threaded union locking system and precision ball-type check valves, are designed for extreme high pressure applications such as found on portable hydraulic rams.

• Machined from solid steel bar stock for durability.
• The "W" Series has a threaded sleeve locking mechanism, mates with matching male threads on the plug. The two halves must be manually threaded together for connection.
• Hard, chrome alloy balls are used for valving. They are spring loaded for positive sealing of the valve.
• The valve provides a metal-to-metal seal between the ball and a coined seat.
• The body seal is polyurethane which resists high pressure extrusion.
• A threaded valve retainer provides a valve stop that assures positive valve alignment.
