Connect under pressure nipple
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 con­struc­tion
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.
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
Performance
Connect Under Pressure Operation
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.
