KZE-B Series
KZE-B couplings use a threaded union locking system and precision ball-type check valves for extreme high-pressure applications such as portable hydraulic jacks.
Features
- Machined from solid steel bar stock for durability.
- A threaded sleeve locking mechanism mates with the male thread on the nipple; both halves are manually threaded together for connection.
- Hard chrome-alloy balls are spring loaded and held firmly against the valve seat.
- The valve provides a metal-to-metal seal between the ball and coned seat.
- The polyurethane interface seal resists high-pressure extrusion.
- A threaded valve retainer provides a positive valve stop and reliable alignment.
- Compatible with PARKER 3000 and FASTER PVVM series.
