Applications
Parker FC Series nipple provides connect-under-pressure capability with up to 3000 PSI of trapped pressure in the nipple. FC Series nipples are ideal for applications where residual pressure makes reconnect difficult. Utilized primarily in the construction equipment market, FC Series nipples are commonly found on hydraulic attachments used in skid steer applications. The FC Series nipples mate with the Parker FF Series couplers. FC Series couplers are not produced.To connect an FC Series nipple holding residual pressure (up to 3,000 psi) with a non-pressurized FF Series coupler, do not insert the nipple in to the coupler all at once. Insert the nipple only partially at first, then pause momentarily to allow pressure to equalize, then push the nipple in all the way to complete the connection.

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.
