A seal includes a seal body disposed about a seal axis and configured to be mounted to a first component at a second axial end of the seal body. The seal body includes an interior surface defining a seal gland circumferentially extending about the seal axis. A packing is disposed within the seal gland. A retaining ring is in communication with a second radial side of the packing and is disposed within the seal gland. A plurality of exciter springs are mounted to a second radial side of the retaining ring. The plurality of exciter springs are biased against the interior surface of the seal body and are configured to center the packing within the seal body. The packing is configured to receive a second component and form a seal interface between the packing and the second component. The seal body is configured to form a portion of a passage.

A gas turbine engine includes a compressor section, a combustor, and a turbine section. A bleed tap taps air from the compressor section through a bleed valve. The bleed valve is selectively opened by a control to dump air from the compressor section to a dump outlet. A heat exchanger duct includes a duct air inlet to cool a fluid in a heat exchanger and a duct air outlet. The dump outlet is within the heat exchanger duct.

An assembly is provided for a fluid system. This fluid system assembly includes a fluid conduit and a plug. The fluid conduit has an internal bore. The internal bore is configured as or otherwise includes a smooth-walled internal bore. The plug includes a protrusion and a head. The protrusion is connected to the head. The protrusion projects axially along an axial centerline partially into the smooth-walled internal bore to a distal end of the plug. The head is seated against the fluid conduit. The head seals an opening in the fluid conduit to the internal bore.
