The 1000006289 Buttweld Braided Metal Hose has a 0.75 in. outside diameter short weld stub, a 40 in. overall length and a 0.065 in. wall thickness. Stainless Steel braided vacuum hose is flexible yet resistant to contraction making it ideal for rough pumping lines. It features a short weld stub on each end for buttwelding to vacuum tubing or fittings. Series 23 vacuum buttweld fittings are constructed with welded, drawn, and annealed 304 stainless steel tubing for applications where minimizing the number of sealed joints is critical. Stainless steel vacuum tubing offers low outgassing under vacuum conditions, is chemically resistant, annealed for consistent leak free welding, and has minimized corrosion concentration points. Series 23 fittings are designed for internal socket type welding or external buttwelding.
