Stainless Steel Vacuum Tubing, 1.5 in. OD x 0.065, Polished, KF40 CF2.75, 4x10 Ft Sticks ($12.32/ft)

Grade A Stainless Steel Vacuum Tubing, 1.5 in. OD, Polished, 0.065 in. Wall, KF-40 or NW-40 Flanges, Sold Per 4x10 Foot Stick ($12.32/ft)
ASTM A269 Grade Mechanically Polished Tubing (Mirror-Like) ID Surface Finish of 20 μin RA And OD Surface Finish Of 32 μin RA

Ideal Vacuum offers high-quality 304L stainless steel (Grade A) tubing which is an excellent choice for use in vacuum systems and vacuum components. Our stainless steel tubing has been mechanically polished which gives a (mirror-like) ID surface finish of 20 μin RA and OD surface finish of 32 μin RA. Our premium tubing is manufactured in accordance with ASTM A269 and is commonly used in both high-vacuum and sanitary grade applications. Welded tube manifolds and fittings are often used in vacuum applications to help minimize the number of sealed joints in a system. Our grade A 304L stainless steel vacuum tubing is bright annealed and mechanically polished with maximum roughness measurement of 32 Ra O.D. and 20 Ra I.D.

Our premium welded 304L stainless steel tubing can be used as Sanitary Tubing to meet the demanding environments of the dairy, food, and beverage industries which require a higher purity tubing than standard instrumentation grade. Sanitary tubing applications require a highly polished ID and OD to ensure cleanliness and prevent particulate entrapment. ASTM A269 specifications require seamless & welded austenitic stainless steel tubing for general service applications.

A 269 Vacuum Tubing Features:

  • Low outgassing under vacuum
  • Chemically resistant
  • Annealed for consistent leak free welding
  • Minimized corrosion concentration points

To ensure high quality stainless steel tube welds:

  • 1. Always start with clean and properly weld prepped components.
  • 2. For internal welds, minimize warping by using only enough heat for 60-75% penetration.
  • 3. For external butt welds, ensure 100% penetration with no internal cracks or crevices.
  • 4. Do not weld internally then externally around the entire circumference of the fittings.
  • 5. Make sure there is little or no gap between pieces to be welded.
  • 6. Ensure that all heat-affected surfaces, especially on the vacuum side, are purged with inert gas.
