IS 9975 : Part 3 : 1984 Specification for `O Rings - Part 3 : Seal Housing Dimensions, Tolerances and Design Criteria for Standard Applications

1 Scope

Covers `O -ring housing, dimensions and associated tolerances.

1.1 Design criteria is based on elastomeric compounds of 70IRHD, working at pressures up to 10 MPa and temperatures between-30�C and +100�C. For other workingconditions (pressures, temperature, etc) it may be necessary toselect suitable elastomeric compounds of other hardnesses or toincorporate anti-extrusion rings.
