*1. All dimensions are in mm unless otherwise specified.

*2. Material and hardness specification for ring gaskets is listed.

*3. Tolerances of Type R ring gasket dimensions:

A = width of ring, +0.20, -0.00

C = width of flat, +0.15, −0.00

D = hole size, ±0.5
H = height of ring, +0.20, −0.00
OD = outside diameter of ring, +0.00, −0.15
ODT p outside diameter of flat, ±0.05
R = radius of ring, shall be 8% to 12% of the gasket height, H
23 deg = angle, ±0 deg 15 min.

*4. One pressure passage hole is required per gasket as illustrated.
The centerline of the hole shall be located at the midpoint of dimension C.
