The PARKER 12-12 FBZ-B is a brass compression tube connector designed to join 3/4 inch OD tubing to a male NPT threaded port. It creates a secure, leak-resistant mechanical connection without soldering or flaring. The fitting is rated to 1900 psi maximum working pressure and is manufactured from brass meeting ASTM B-453 and ASTM B16 standards. With an overall length of 1.99 inches, it is a compact, inline connector suited for hydraulic, pneumatic, refrigeration, and fluid distribution lines. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting in both residential and light commercial applications where a reliable tube-to-pipe transition is needed.
This connector is used wherever a 3/4 inch OD compression tube must terminate or transition into an NPT-threaded component such as a valve body, manifold, or instrument port. Its compression-style end eliminates the need for solder, making it appropriate for systems that cannot tolerate heat during assembly. Typical installation scenarios include potable water distribution, refrigerant piping accessories, instrument air lines, and hydraulic control circuits. The NPT thread end seats against standard tapered pipe threads for a pressure-tight seal.
Designed as an OEM-style compression fitting for use with 3/4 inch OD tubing and male NPT-threaded ports following standard NPT thread specifications. Cross-referenced as Swagelok part number B-1210-1-12 for procurement reference.
Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and IPC or IFGC guidelines. Shut off system pressure and depressurize the line completely before disassembling or installing any compression fitting. Hand-tighten the compression nut onto the fitting body, then advance with a wrench per standard compression fitting practice — do not overtighten, as this can deform the ferrule and compromise the seal. Inspect the tube end for burrs or ovality and deburr as needed before insertion to ensure a proper ferrule seat.
