Specification of METTAL JACKET
SPIRAL WOUND GASKET
METTAL JACKETED
・When placing an order for a gasket, please specify the dimensions
A, B, C, R1, R2, and R3 shown in the diagrams. In the case of a
diamond shape, if R3 is a straight line, there is no need to specify
R3.
・ In the case of an elliptical or track type, dimension A must be at
least 40mm. In the case of a diamond type, dimension A must be at
least 60mm.
・The ratio A/B must be at least 2/3.
・ Because this type of gasket may break apart, ensure that the
straight part (indicated by ★ in the diagrams below) is no more
than 100mm, as a rough guide. If it is necessary to use a straight
length of more than 100mm, use TOMBOTM No.1880-GR (CMGC
gasket).
