GASkETS
GRINNELL Gasket Grade & Recommendations
Tech Data Sheet: G610
The Gasket Recommendation Table has been developed to assure maximum service life . The table was developed from information supplied by the material manufacturers of the elastomer, technical reference literature, and testing conducted by GRINNELL Mechanical Products .
In evaluating the gasket grade for intended service applications the following consideration must be reviewed: system operating temperature, fluid or solution concentration, and duration of service .
All gasket recommendations are based on a temperature of 21°C (70°F) unless otherwise noted .
Technical and Engineering Services should be consulted (Phone 1300 725 688, Fax +61 3 9933 6204) if combinations of service solutions are being considered .
Contact GRINNELL Mechanical Products for recommendations for services not listed .
Gasket recommendations apply to GRINNELL gaskets and valves only .
