GASKET THICKNESS. TO ENSURE GREATER GASKET STABILITY; FOR LARGER DIAMETER ABOVE 39” (1000 mm)
WE RECOMMEND 7.2 mm (0.285 in) THICK GASKETS WITH 5.O mm (0.197 in) THICK GUIDE RINGS, OR 6.4 mm (0.250 in)
THICK GASKETS WITH 4.8 mm (O.188 in) THICK GUIDE RINGS.
†OUTSIDE DIAMETER, FACING DIAMETER AND DRILLING OF CLASS 75 BLIND FLANGES DEPEND ON WHETHER
THEY ARE TO BE USED AGAINST WELD-NECK OR SLIP-ON FLANGES.
*WHERE STYLE CGI GASKETS ARE REQUIRED, INNER RING I.D. MUST BE SPECIFIED. STANDARD PRACTICE IS TO
USE INNER RINGS WITH AN I.D. THAT IS 3.2 mm (0.125 in.) GREATER THAN THE FLANGE BORE.
