Gaskets
201207A – AQTTB
Date Issued: 24 July 2012
Aquatherm recommends using a full-face rubber (black EPDM or red SBR) gasket with its flanges. Viton® gaskets may also be used if needed for chemical resistance. The bolt and bolt torque do not change with these different gasket materials. Other materials may require different bolt torque. The gasket should have an inside diameter consistent with the ID of the flange adapter. For lower pressure systems, and smaller diameters (4” and down), ring gaskets may be used but there is the possibility of blow-outs during pressure testing. Ring gaskets are also more susceptible to leaks if the flanges and connected piping are not aligned properly during installation. The gasket should have an inside diameter consistent with the ID of the flange adapter.
It is important to note that any gasket material used, whether purchased from Aquatherm or another source, is not covered under the Aquatherm warranty program.
On the following pages please find a Flange Adapter Table listing the dimensions of the various flange adapters available from Aquatherm. This table may be used in selecting the proper size gasket for various sized flange adapters.
Also, please find a short listing of some alternative gasket manufacturers. These manufacturers have a large variety of different gaskets and materials available. Please contact the individual manufacturers for specific details concerning price and availability.
