VICI Valco 1/16” High Pressure PEEK Bulkhead Internal Union with 0.25 mm Bore - Fingertight

This bulkhead zero dead volume union connects 1/16” OD tubing with 1/16” zero dead volume internal fittings. It has a bore size of 0.25 mm, the panel hole diameter is 3/8”. 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. 

Typically the mounting nut goes inside the instrument, so that the long threaded portion will be out of sight. Internal unions have female threads and a fitting detail for zero volume fittings. The nuts have male (external) threads. 

• With a bulkhead union, an O-ring can be installed between the body and the panel to allow operation in purged environments.

• Select the union with the bore that matches the ID of the tubing. If the IDs are different, choose the union with a bore that matches the smaller tube bore.
