Borosilicate glass process pipe reducing elbow is suitable for full vacuum service.
Elbows are compatible with all Durability Acids except Hydrofluoric or Phosphoric with fluorides. Some durability alkalies attack above 120°F and above ph 11.
Vertical length is measured from the center line of horizontal pipe to the top of the vertical leg. Horizontal leg is measured from the center line of the vertical leg to the top of the horizontal leg. Glass meets ASTM and USP Type 1 specs for borosilcate glass and Federal spec DD-G-541B. Process pipe can be constructed by a contractor to meet ASTM spec C1053-90, ASTM spec C1053-00, Federal Spec DD-G-541B, Military spec MIL-P 2256B(YD).
