Warning: never run hydrocarbon contaminated fluid through this valve. The internal EPDM seal is subject to severe swelling if 99% pure methanol is not used. Always use 99% methanol from a factory sealed canister. Transfer pump or jugs should be free of any previous hydrocarbon usage. Washing the container with detergent will not stop methanol drawing out the hydrocarbon from a plastic container laced with gasoline.
