Bleach and chlorine need EPDM seals, not VITON, because VITON degrades against sodium hypochlorite over time while EPDM holds up. This is the seal pairing most people get backwards, since VITON is the default for so much else.

Why EPDM, not VITON
VITON is excellent for acids and solvents but slowly perishes against sodium hypochlorite. EPDM shrugs off bleach and chlorinated water. For mould and sanitising, a foamer holds chlorine on the surface longer. See the Chemical Compatibility Guide.

Common questions
Why does bleach need EPDM, not VITON?
VITON degrades against bleach over time. EPDM resists sodium hypochlorite and chlorine well.
Can I spray sodium hypochlorite?
Yes, with EPDM seals. Confirm concentration against the SDS for strong solutions.
Best sprayer for chlorine sanitising?
An EPDM-sealed pressure sprayer or foamer. Foaming adds dwell time for better sanitising.
