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.
