Ham-let 3002421 Compression Bulkhead Union 316 Ss

Product Description

The HAM-LET 3002421 is a compression tube bulkhead union designed for through-panel or through-wall tube connections in instrumentation, pneumatic, and process piping systems. Built from 316 stainless steel and conforming to multiple ASTM and DIN material standards, this fitting joins two compression tube ends through a bulkhead surface without requiring welding or threaded fittings. The overall length is 2.02 inches and the unit weighs 0.25 pounds. Rated for service down to -20 degrees F, it is suited for installations where temperature cycling and corrosion resistance are critical. Licensed tradespeople working in industrial, commercial, and OEM panel-fabrication environments are the primary installers.

This bulkhead union is appropriate for use in instrument enclosures, control panels, and process equipment where tubing must pass cleanly through a panel wall while maintaining a secure, leak-resistant compression seal on both sides. The 316 stainless steel construction and compliance with ASTM A182, ASTM A213, ASTM A269, ASTM A276, ASTM A479, DIN EN10122-5, and DIN EN10272 make it a fit for corrosive or high-purity service environments. Cross-references the Swagelok part number SS-200-61 for specification matching.

Key Features

• Compression x compression end connections on both sides for tool-assisted, weld-free installation
• Bulkhead union design allows tubing to pass through panel walls or enclosure surfaces
• Overall length of 2.02 inches for compact panel layouts
• Rated for service to -20 degrees F minimum temperature
• Cross-references Swagelok part number SS-200-61

Compatibility

Cross-references Swagelok part number SS-200-61. Designed as an OEM-style replacement or direct equivalent for compression tube bulkhead unions in instrumentation and process piping applications requiring 316 stainless steel construction.

Installation Notes

Installation is typically performed by licensed pipefitters, instrumentation technicians, or plumbers working under applicable piping codes. Depressurize and isolate the tubing circuit fully before disassembling any existing fitting. Use the appropriate wrench flats provided on the fitting body and follow the compression fitting manufacturer's recommended turns-past-finger-tight procedure for the tube size being used. Do not over-torque the compression nut, as this may deform the ferrule and compromise the seal.
