0.334" Hose | McMaster-Carr

Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.

304 stainless steel has very good corrosion resistance.

316 stainless steel offers excellent corrosion resistance.

Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.
