An apparatus for use in the bearing compartment of a gas turbine engine includes a first conduit and a second conduit. The first conduit defines inner and outer surfaces between an inlet end and an outlet end. The second conduit defines inner and outer surfaces between an inlet end and an outlet end. At least a portion of the second conduit is substantially coaxial with and enclosed by at least a portion of the first conduit. One of the first conduit or the second conduit is a lubricant feed to the bearing compartment. The other of the first conduit and the second conduit is the air vent from the bearing compartment.
