Ham-let 3101825 Compression Tube Union Brass

Product Description

The HAM-LET 3101825 is a brass compression tube union designed to join two compression-end tubing runs in a single inline connection. Manufactured from brass conforming to ASTM B68 and ASTM B75, this union provides a reliable leak-resistant joint without soldering or threading. At 1.85 inches overall length, it fits in tight plumbing, instrumentation, and fluid-system installations. The compression-by-compression end configuration allows technicians to connect two tube ends quickly using standard compression nuts and ferrules. This fitting is appropriate for low-pressure fluid and gas lines where a removable, re-enterable union connection is required.

This union is suited for residential and light commercial plumbing, instrumentation tubing systems, and HVAC refrigerant or sensing-line applications where an inline union fitting is needed. It is also cross-referenced to Swagelok part number B-810-6-4, making it a recognized replacement or alternate source option in instrumentation and process-line work. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers for this type of fitting in both new construction and service applications.

Key Features

• Brass construction meets ASTM B68 and ASTM B75 material standards
• Compression x compression end connections on both sides for tool-assisted, solder-free assembly
• 1.85-inch overall length fits compact tube runs and tight enclosures
• Rated for service down to -20 degrees C and up to 37 degrees C
• Cross-referenced to Swagelok B-810-6-4 for direct replacement sourcing
• Single-piece union body allows inline disconnection and reconnection of tubing

Compatibility

Cross-referenced as an equivalent to Swagelok part number B-810-6-4. Designed as an OEM-style replacement compression tube union for instrumentation, plumbing, and fluid-system tubing applications using compression-end connections.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified instrumentation technician. Shut off and depressurize the tubing system completely before disassembling any compression fitting. Use appropriate tube cutters and deburring tools to ensure square, clean tube ends before inserting into the compression body. Follow applicable IPC or IFGC code requirements for the fluid or gas service involved.
