Del-Weld™ Tube Fittings include elbows, tees and multiple crosses which are supplied without flanges. The vacuum connection is made by welding, brazing, or soldering to the vacuum system.<\/p>\n

MDC Del-Weld™ fittings are supplied in vacuum shrink wrapped packages, ready for high vacuum service. Interior surfaces of components should not be touched with bare hands when opening packages.<\/p>\n

Vacuum tubing is welded and drawn over a mandrel when hot. A slight seam is visible.<\/p>\n

Vacuum tubing is specified by tube O.D. and wall thickness. The I.D. of vacuum tubing is theoretical, calculated as the tube O.D. less twice the wall thickness. Vacuum tubing does not have tolerances relating to concentricity, ovality, triangulation or other specifications.<\/p>\n

Tubing or fittings requiring a machined length, an electropolished or special finish must be specified and quoted as a special order.<\/p>\n<\/div>\n
