Parker 4-4-4 Sbz-b Compression Male Branch Tee 1/4 in Brass

Product Description

The PARKER 4-4-4 SBZ-B is a brass compression tube male branch tee designed for precision fluid and gas line connections in demanding trade applications. It features a three-port tee configuration with compression fittings on two ends and a male NPT (MNPT) threaded connection on the branch port. Manufactured from brass to ASTM-B-453 and ASTM-B16 standards, this fitting is rated for a maximum working pressure of 3500 psi. Its overall length is 2.12 inches. HVAC technicians, plumbers, and instrumentation professionals install this fitting where a branch takeoff and inline tube connection are required in a single compact body.

This fitting is suited for residential and light commercial HVAC systems, refrigeration lines, instrumentation tubing, and plumbing applications that call for a reliable branch connection with mixed end types. The compression-by-compression-by-MNPT configuration allows it to join tubing on two ports while threading directly into a valve, manifold, or equipment port on the branch. The 1/4 inch thread size and compatible Swagelok cross-reference part number B-400-3-4TTM make it a recognized option in instrumentation and process piping work.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation technician. Shut off and depressurize the system completely before disassembly or fitting installation. Compression fittings require proper tube preparation — ensure tube ends are cut square, deburred, and fully seated before tightening the compression nut. Do not overtighten; follow the fitting manufacturer's recommended turn count from finger-tight for compression connections.
