Parker 6-4 Fbz-b Compression X Mnpt Brass Tube Connector

Product Description

The PARKER 6-4 FBZ-B is a straight brass compression tube connector designed to join 1/4 inch compression tubing to a male NPT threaded port. Machined from brass and meeting ASTM-B-453 and ASTM-B16 standards, this fitting delivers a secure, leak-resistant connection in fluid and gas line applications. It carries a maximum working pressure of 2300 psi, making it suitable for moderate- to high-pressure service. At 1.57 inches in overall length, it is a compact, single-piece connector. Plumbers, HVAC technicians, and industrial pipefitters install this fitting where a tube-to-threaded-port transition is required in tight or confined spaces.

This connector is used in residential and commercial plumbing, HVAC refrigerant line accessories, pneumatic control systems, and instrumentation tubing runs. It is well suited for any application requiring a reliable compression-to-male-pipe-thread transition in a straight-run configuration. The brass construction resists corrosion in water, air, and compatible fluid service, making it a standard choice across HVAC, plumbing, and light industrial trades.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians. Shut off and depressurize the line before disassembly or installation. Hand-tighten the compression nut onto the tube, then use an appropriately sized wrench to achieve a snug, leak-free seat without overtightening the brass threads. Verify the installation meets applicable local plumbing codes and pressure ratings for the intended service.
