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.
Performance
Features
• Connect-Under-Pressure nipple.
• Hardened locking surface.
• Steel construction, Chromium-6 Free plating
for corrosion resistance.
• Anti blowout Nitrile/PTFE bonded nipple seal.
• Flush face valving.
Applications
Parker FEC Series nipple provide connect-under-pressure
capability with up to 3000 PSI of trapped pressure in the
nipple and are ideal for applications where residual pressure
makes reconnect difficult. Utilized primarily in the construc-
tion equipment market, FEC Series products are commonly
found on hydraulic attachments used in skid steer
applications.
The FEC Series mates with the FEM Series
interface ISO 16028 couplers.
Description
FEC Series products operate slightly different from traditional
non-spill couplings. With no pressure in the coupler and up to
3000 PSI of trapped pressure in the nipple, begin to couple
the mating halves. Delay momentarily during connection to
allow trapped pressure to equalize with the mating half
before completing the connection.
