Connect Under Pressure Operation
FC 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.
FC Series nipples provide a connect-under-pressure option for
trapped pressures up to 3000 psi on the nipple side.
Features:
•
Connect-under-pressure nipple
•
Flush, non-spill valving
•
Hardened locking surface
•
Blow-out resistant seal
•
Protective zinc plating with clear trivalent chromate finish
Applications include:
•
Hydraulic tools
