EPDM Rubber Flange Gaskets are often used for sealing water lines and pipes. This variation is made from our Potable Water grade of EPDM Rubber Sheet which meets the requirements of AS/NZS 4020 (2005) Testing of Products for Use in Contact with Drinking Water. It also conforms to the requirements of WSA 109 2011 Table 2.1.
The rubber these gaskets are made from is our Black, 65 Duro Potable Water Grade EPDM. This is a high quality, industrial-grade EPDM that meets all the requirements of AS/NS 4020 as well as WSA 109 2011 Table 2.1.
Though most commonly used for sealing in application where the gasket will be exposed to drinking water, this EPDM does exhibit many other characteristics including good chemical resistance, excellent resistant to UV and good physical strength. It has a shore hardness of 65 Duro (±5). Maximum elongation is 350% and tensile strength if 11 MPa.
More information on this rubber can be found on our EPDM Rubber Sheet for Potable Water Sealing Technical Data Sheet.
This page lists ring types gaskets. This style of gasket is designed to sit inside the bolts of the flanges and is known by quite a few names, including:
Theseg askets are all cut to suit BS 3063 Flanges in either Table D or Table E configurations (the two most common). In almost all pipe nominal bores (except 150NB, 200NB & 300NB) there’s no difference in gasket size between Table D or Table E (the gasket fits both) when using ring type gaskets.
For those where there is a difference, both Table D and Table E variations are offered separately.
