Sodium Hypochlorite is a very common storage application. It is harmed by UV rays and by heat. The use of a light or white colored tank with opaque walls is recommended. PVC Fittings are good while PVDF fittings are more expensive but excellent. Viton gaskets are excellent.
HDPE is the most economical tank material for Sodium Hypochlorite (<20%), rated Excellent. Polypropylene and PVDF (Kynar®) are also rated Good or better. Avoid nylon tanks. Rated Fair (contact us before use): 316 stainless steel hardware.
