Ham-let 3600055 Compression Tube Back Ferrule Brass

Product Description

The HAM-LET 3600055 is a brass compression tube back ferrule designed for use in compression tube fittings. The back ferrule works in tandem with a front ferrule and fitting body to create a leak-tight mechanical seal on the tube OD. Manufactured from brass in conformance with ASTM B68 and ASTM B75 standards, this ferrule provides reliable sealing performance in fluid and gas distribution systems. Licensed plumbers, pipefitters, and instrumentation technicians install this component as part of compression fitting assemblies where repeatable, tool-assisted connections are required.

This back ferrule is suited for residential, commercial, and light industrial compression tube fitting applications. It is used in pneumatic, hydraulic, and fluid handling lines where a secure tube OD connection is needed. The ferrule is sold individually per package and must be ordered in multiples of five. It is rated for service from -20 degrees C to 37 degrees C, making it appropriate for ambient and moderate-temperature process lines. Cross-reference: Swagelok part number B-604-1.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or instrumentation technicians. Depressurize and isolate the line completely before disassembling any compression fitting. The back ferrule seats behind the front ferrule in the fitting body and requires proper tube preparation, including a clean square cut and deburring, before assembly. Follow the fitting manufacturer's written instructions for make-up turns to avoid over-tightening, which can damage the ferrule or tube wall.
