Value Collection SS-TI-D8 Compression Tube Insert 1/2 in

Product Description

The VALUE COLLECTION SS-TI-D8 is a stainless steel compression tube insert designed to reinforce soft or thin-walled tubing in compression fitting assemblies. Manufactured from 316 stainless steel, this insert slides inside the tube end to prevent collapse when the compression fitting is tightened, maintaining a secure and leak-resistant seal. With an overall length of 0.5 inches and a 3/4-20 UNF thread size, it is a compact, precision-made component suited for high-purity and corrosion-resistant fluid and gas line applications. Installation is performed by licensed plumbers, pipefitters, and instrumentation technicians working on tube-and-fitting systems.

This compression tube insert is used in residential and commercial fluid handling systems where 1/2 inch OD tubing connects to compression-style fittings. It is particularly common in instrumentation, chemical processing, hydraulic, and HVAC refrigerant or pneumatic line assemblies where tubing integrity at the fitting junction is critical. The SS-TI-D8 meets multiple material and dimensional standards including ASTM A182, ASTM A213, ASTM A269, ASTM A276, ASTM A479, DIN EN10122-5, and DIN EN10272, making it appropriate for demanding service environments. It corresponds to Swagelok part number SS-815-6.

Key Features

• 316 stainless steel construction provides excellent corrosion resistance in wet, chemical, and high-purity service environments
• 0.5 inch overall length fits standard compression fitting assemblies for 1/2 inch OD tubing
• 3/4-20 UNF thread size ensures precise dimensional compatibility with mating compression components
• Meets ASTM A182, A213, A269, A276, A479, DIN EN10122-5, and DIN EN10272 standards
• Tube OD x Tube ID end connections suit direct in-line insertion without special tooling
• Lightweight at 0.01 pounds, minimizing added load in tight instrumentation or panel installations

Compatibility

Corresponds to Swagelok part number SS-815-6. Designed as an OEM-style replacement or supplemental component for compression fitting systems using 1/2 inch OD tubing with a 3/4-20 UNF thread standard.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or instrumentation technicians. Before servicing any fluid or gas line, depressurize and isolate the system completely and verify that all residual pressure has been relieved. Insert the tube insert fully into the tube end before seating the tube into the compression fitting body. Follow all applicable codes including ASTM standards listed for this component, and do not overtighten compression fittings, as this can deform the ferrule and compromise the seal.
