FAQ

Gambit oil resistant gasket sheets gain their chemical characteristics by virtue of using nitrile butadiene rubber (NBR). However does not impede their resistance to weak aqueous solutions of salts, acids and bases. More information on individual gasket sheets can be found in our product catalogue.

The Guidelines of European Sealing Association (ESA) lay down that pump stuffing boxes should work with controlled leakage. This leak rate lowers the packing’s friction against the shaft and drives the heat away from the friction point. However, in some particular cases that do not involve high working temperatures it is possible to have leak free functioning with the use of packings that have low friction coefficient, good thermal conductivity,  and outstanding temperature resistance.

It is not the correct understanding. That piece of information communicates that gaskets made of AF-400 material will be tight under 12 MPa pressure provided that optimal working conditions are the case. Specific working conditions, assembly procedure, quality of flanges, etc., may substantially reduce maximum working pressure. If in doubt, you should base any decisions over the usage on calculation procedures available in standards.

During the production process, because of technological reasons, the yarn contains 20% of cellulose. At the first stage of work, burning out cellulose takes place. The thermal insulation material maintains its properties.

They have similar friction coefficients, clamp and maximum friction speed. The BAC type features higher maximum working temperature, but being a ceramic band, it is abrasive to a brake drum. The ATU type works better with a brake drum, but its maximum working temperature is lower.

Everything depends on operation conditions. Graphite works better in reducing environment, whereas aluminosilicates work out  in oxidizing environment. Graphite is tighter than aluminosilicates, but less elastic than them at the same time.
