Value Collection 35965 Seamless Ss Tube 1/4 in Od 321

Product Description

The VALUE COLLECTION 35965 is a seamless round tube machined from 321 stainless steel, a titanium-stabilized austenitic alloy well suited to high-temperature and corrosion-exposed environments. The tube measures 1/4 inch outside diameter with a 0.035-inch wall thickness and an inside diameter of 0.180 inches, running 6 feet in length. It meets AMS5570 and MIL-T-8808 standards, making it appropriate for aerospace, industrial, and process-system fabrication where dimensional consistency and material traceability are required. Installation and fabrication are handled by machinists, pipefitters, and mechanical contractors working to engineering specifications.

This tube is used in applications requiring elevated heat resistance and resistance to intergranular corrosion after welding - conditions where standard 304 or 316 stainless may sensitize. Typical uses include hydraulic and instrumentation lines, heat exchanger tubing, aerospace fluid systems, and high-temperature process piping. The seamless construction eliminates weld seams along the tube body, supporting pressure integrity in demanding service conditions. Sold as a single 6-foot length.

Key Features

• 321 stainless steel alloy - titanium-stabilized for resistance to intergranular corrosion after welding
• Seamless construction - no longitudinal weld seam, consistent wall integrity along full length
• Meets AMS5570 and MIL-T-8808 material standards
• 0.035-inch wall thickness with 0.180-inch inside diameter
• Round tube profile - compatible with standard tube fittings and compression fittings sized for 1/4-inch OD
• 6-foot length suits cut-to-size fabrication work

Compatibility

Designed for use with standard 1/4-inch OD tube fittings, ferrule-style compression fittings, and fabricated assemblies requiring AMS5570 or MIL-T-8808 compliant 321 stainless seamless tubing.

Installation Notes

Cutting and fitting of stainless steel tubing should be performed by a qualified pipefitter or machinist using tooling rated for stainless alloys - standard carbon-steel cutting tools can contaminate the surface and reduce corrosion resistance. Deburr all cut ends before installing compression or flare fittings to ensure a leak-free seat. Follow applicable system design codes and engineering drawings for pressure ratings, since rated pressure depends on application temperature and fitting type, not tube dimensions alone.
