4200 Series
Features
Parker 4200 Series couplings feature:
• Double acting sleeve for one handed push-to-connect
operation when coupler is clamp or bulkhead mounted.
• 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.
Applications
The 4200 Series brings to the industry a proven design
for use on construction equipment, forestry equipment
agricultural machinery, and oil tools.
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.
