Product Notes:
BASE PART NUMBER: As shown here, the BASE PART NUMBER defines the Series (three characters), the material (one character), the nominal size, the maximum thickness H1, and the minimum thickness H2. Use a decimal number to indicate the nominal size. Then replace H1 and H2 in the part number with the maximum and minimum thicknesses in decimals. For maximum thicknesses over 6”, contact factory. Note that the Class (or lb.) designation does not imply a pressure rating.
For example, a 3/4” Class 150 PTFE Tapered Full-Face Flange x 1” thick (H1) x 3/4” thick (H2) would
be STFT-0.75-1-0.75
Options
CLASS 300 (300 lb.) SPACERS: For Class 300 spacers, add to the BASE PART NUMBER the suffix 300. For other classes, contact the factory. For example, a 2” Class 300 PTFE Tapered Full-Face Flange x 1-1/2” thick (H1) x 1” thick (H2) would be STFT-2-1.5-1-300
DOUBLE TAPER: For Double Tapered Flanges, contact the factory.
