Ham-let 3001547 Compression Tube Insert 316 Ss

Product Description

The HAM-LET 3001547 is a compression tube insert fitting machined from 316 stainless steel and designed to reinforce soft tubing at compression fittings. The insert is placed inside the tube end before assembly, preventing tube collapse when the compression nut and ferrule are torqued. It provides a firm, concentric seating surface that maintains tube roundness and ensures a leak-free seal under pressure. With an inside diameter of 0.170 inches and material certified to ASTM A182, ASTM A213, ASTM A269, ASTM A276, and ASTM A479 standards, this insert suits instrumentation, process, and high-purity fluid systems where fitting integrity is critical. It is installed by licensed plumbers, HVAC technicians, and instrumentation fitters.

The 3001547 is suited for use in residential and commercial applications where soft tubing such as copper or plastic is terminated at a compression fitting. End connections are tube OD on the fitting side and tube ID on the insert bore. The insert is compatible with systems operating between -20 degrees F and 37 degrees C (approximately -4 degrees F minimum per conversion). Typical installation scenarios include instrument tubing runs, refrigerant line accessories, and hydraulic or pneumatic instrumentation circuits requiring reliable tube-end support.

Key Features

• 316 stainless steel construction meets ASTM A182, A213, A269, A276, A479, DIN EN10122-5, and DIN EN10272 standards
• Inside diameter of 0.170 inches for precise tube ID fitment
• Prevents tube collapse and maintains concentricity during compression fitting assembly
• Rated for service down to -20 degrees F, suitable for low-temperature applications
• Tube OD by tube ID end connections for direct use inside standard compression fittings
• Lightweight at 0.25 pounds, sold as a single-piece unit

Compatibility

Designed as an OEM-style replacement or supplemental component for use with standard compression fittings requiring tube insert support in 316 stainless steel instrumentation and fluid-handling systems.

Installation Notes

Installation is performed by licensed plumbers or instrumentation technicians. Shut off system pressure and depressurize all lines before disassembling any fitting. The insert is placed fully inside the tube end prior to sliding on the compression nut and ferrule. Do not force the insert into undersized tubing, as deformation will compromise the compression seal.
