Parker 4 Kbz-ss Compression Tube Union Stainless Steel

Product Description

The PARKER 4 KBZ-SS is a stainless steel compression tube union designed to join two compression-end tube lines in a single inline fitting. It creates a leak-resistant, metal-to-metal sealed connection rated to 10300 psi maximum working pressure. The all-compression end connections on both sides eliminate the need for welding or soldering, making installation faster and repeatable. This fitting is used in high-pressure fluid and gas distribution systems where corrosion resistance and pressure integrity are both critical requirements. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers.

The 4 KBZ-SS is suited for residential and commercial plumbing, hydraulic instrumentation lines, pneumatic control circuits, and process piping applications where stainless steel is specified for corrosion resistance or sanitary requirements. Its all-compression design makes it appropriate for tubing runs that may require periodic service or disassembly without cutting and re-flaring. The fitting is sold individually and is compatible with standard compression tube sizes corresponding to the Parker KBZ series designation.

Key Features

• All-compression end connections on both sides for tool-accessible, weld-free assembly
• Stainless steel construction provides corrosion resistance in wet, chemical, or outdoor environments
• Rated to 10300 psi maximum working pressure for high-pressure line service
• Inline union configuration allows straight tube-to-tube joining without offset or angle
• Single-piece packaging with a minimum order quantity of one unit

Compatibility

Designed as an OEM-style compression union fitting for use in high-pressure tubing systems requiring stainless steel construction and all-compression end connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC or facility piping codes. Shut off and depressurize the line completely before removing or installing any compression fitting. Use the correct tube OD and ensure tubing ends are cut square and deburred before seating the ferrule. Do not overtighten compression nuts, as stainless ferrules can gall; hand-tighten then advance with a wrench per the fitting manufacturer standard procedure.
