These fittings are manufactured with a flange on each end of a "T" shaped section of tubing. Tees accommodate junctions or alignment considerations for vacuum system design. Tees are also used as junction adapters between different tubing sizes or flange types. These fittings are available in all ISO sizes and flange types. ANCORP manufactures standard tees in 304L stainless steel and aluminum. Other materials and flange configurations are available on request.
