The PARKER 6FBC4N-B is a brass bulkhead female connector designed to pass a compression tube line through a panel, bulkhead, or enclosure wall and terminate with a female NPT thread on the opposite side. The fitting uses a compression connection on one end and an FNPT connection on the other, allowing a secure, leak-resistant transition between tubing and threaded pipe. Rated to 2300 psi maximum working pressure, this connector is built to ASME-SB75 and ASTM-B75 brass standards. It is installed by licensed plumbers, HVAC technicians, and instrumentation technicians working with copper or compatible tubing systems.
This connector is suited for use in residential and commercial plumbing, HVAC refrigerant and instrumentation lines, pneumatic control systems, and process piping applications where a bulkhead pass-through is required. The compression-by-FNPT configuration makes it a practical choice when connecting tubing from one side of a panel or enclosure to a female-threaded port or valve on the other side. Overall installed length is 2.17 inches, making it compatible with standard panel cutout depths used in typical mechanical and instrumentation enclosures.
Cross-references to Swagelok part number B-600-71-4. Designed as an OEM-style replacement or direct-fit option for brass bulkhead compression fittings with 1/4 inch FNPT connections in plumbing, HVAC, and instrumentation applications.
Installation should be performed by a qualified plumber or instrumentation technician familiar with compression fitting assembly. Shut off system pressure and bleed the line before removing or installing any compression fitting. Do not overtighten compression nuts, as this can deform the ferrule and compromise the seal. Installations involving potable water or gas service must comply with applicable local codes and standards.
