Features
• Positive valve stop. The perch maintains valve alignment
and provides metal to metal valve stop to insure that the
valves open full–every time.
• Precision machined valves with elastomeric seals provide
for positive shut-off upon disconnection.
• Hardened nipples and sleeves and solid barstock
construction make for a quality coupling with maximum
resistance to damage from hydraulic and mechanical shock.
• Durable ball-locking mechanism assures reliable
connection every time. A large number of locking balls dis-
tributes the work load evenly while providing alignment and
swiveling action to reduce hose torque and prolong hose
life. CAUTION: These products are not to be used as
swivels, rotation under pressure will result in excessive and
premature wear.
• Female pipe (NPSF) standard.
• The standard Fluorocarbon seal is designed to withstand
extremely high pressures and provide reliable sealing.
PTFE back-up ring provides support for the seal in high
pressure applications.
• Sleeve locking mechanism prevents accidental discon-
nection when the coupling is dragged along the ground.
• Steel construction, Chromium-6 Free plating for
corrosion resistance.

Applications
Parker TC series couplings are found in the construction,
railway maintenance and house moving industries. Used on
hydraulic jacking equipment, these couplers eliminate costly
down time caused by improperly connected threaded types.
For use where high pressure capability is required coupled
with positive coupling action. Considerably faster to use than
threaded types.
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.
