NOTE: High pressure PEEK bulkhead reducing unions are non-stock items, available only on a special order basis.
These unions connect two sizes of tubing, using zero dead volume internal fittings on each end.
Bulkhead unions are designed to be mounted through an instrument panel or on a bracket. The fitting body is undercut so that it bites into the panel when the mounting nut is tightened, eliminating the need for a lock washer. An O-ring can be installed between the body and the panel to allow operation in purged environments. Typically the mounting nut goes inside the instrument, so that the long threaded portion will be out of sight.
The 1/32" and 1/16" nuts are fingertight; 1/8" nuts are hex, for wrench tightening. A version with 1/16" and 1/8" hex nuts is also available.
