Two common materials for true union ball valves are viton and epdm.
Epdm rubber ring.
Epdm rubber ethylene propylene diene monomer rubber is a type of synthetic rubber that is used in many applications.
Viton shown in image on the right is a synthetic rubber.
In other forms epdm rubber is used for everything from garden hose to roofing membranes to speaker components.
