4000 Series
Features
Parker 4000 Series couplings feature:
• Poppet valves available to prevent uncoupled leakage.
• Ball valves available for rugged dependability in heavy-
duty hydraulic applications, within rated working pressures.
• Critical parts are induction hardened for durability.
• Dependable ball-locking mechanism holds the mating
halves together.
• Couplers and nipple are precision machined from solid bar
stock.
• For applications with residual trapped pressure use
connect-under-pressure nipples designated by the -DC
option.
• The mating 8010 series nipples meet ISO 5675
requirements.
Applications
The 4000 Series brings to the industry a proven design for
use on construction equipment, forestry equipment,
agricultural machinery, oil tools, steel mill machinery, and
other demanding hydraulic applications.
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
dust plugs and caps for the Parker full line of hydraulic
couplings.
