  1. R The Transparent Specialist COUPLINGS AND GASKETS The couplings used with glass equipment are important from two main points of view: 1. They must ensure the effective seal of the joint. 2. They should not induce any undue stress in the glass. 3. They must be reliable in all service conditions. In this section we have covered coupling to join glass components together as well as to join glass components with a other metal equipment. PTFE bellows are available for normal & vacuum applications, together with flanges to connect them to glass or non-glass equipment. 51

  2. R COUPLINGS COMPLETE COUPLINGS The Transparent Specialist A complete coupling is a set of two backing flanges with insert and nut-bolts. Complete set of flanges require to make a joint & standard one are available in Cast Iron & Mild Steel. Also available in other MOC like Stainless Steel 304 & 316, Siliumin, Bakelite.
