Features
1. Machined from solid steel barstock for durability.
2. The 3000 Series employs a threaded sleeve locking
mechanism, mates with matching male threads on the
nipple. The two halves must be manually threaded
together for connection.
3. Hard, chrome alloy balls are used for valving. They are
spring loaded for positive seating of the valve.
4. The valve provides a metal-to-metal seal between the ball
and a coined seat.
5. The interface seal is polyurethane which resists high
pressure extrusion.
6. A threaded valve retainer provides a valve stop that
assures positive valve alignment.
Applications
Parker 3000 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. See pages noted in Table of
Contents for dust plugs and caps for the Parker full line of
hydraulic couplings.
Note: Protective dust plugs and caps play a crucial role in the
life of a quick coupling and no purchase of a hydraulic quick
coupling is complete without the selection of an appropriate
dust plug and cap. See pages noted in Table of Contents for
hydraulic couplings dust plugs and caps for the full line of
hydraulic couplings.
