Chloramine in Potable Water Systems Causes Rapid Elastomer Deterioration With many of our clients directly involved in the potable water industry, the rubber components we supply must meet strict EPA regulations. For years, the potable water industry has
EPDM (ethylene-propylene-diene-monomer) is a specially designed synthetic rubber for water appliions. The general operating temperature for EPDM is -70 to 300 degrees Fahrenheit making it well suited to most water storage appliions.
EPDM also has good resistance to polar fluids and has great physical properties. With the exception of exposure to di-ester lubricants and petroleum-based fluids, EPDM is a good type of rubber to make items such as cable connectors, insulators, gaskets and hoses, seals, accumulator bladders, and diaphragms.

EPDM Rubber A general purpose medium grade 65/70 sh EPDM/SBR, suitable for low pressure pipe seals, skets, weatherstrip, etc. Excellent water,ozone aqueous chemicals, steam. Also has good mechanical properties and abrasion resistance. available.
Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment. The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with.
Water is another potential hazard that is unable to dent EPDM. After all, it would not be a true outdoor rubber if it could not handle moisture. Normally excessive amounts of water can stain a material, cause it to warp and even cause mold or mildew to form. EPDM

Unit sizes provided in the table 1 and table 2 is in mm, but the size of pipes in the chart is in inch. 1 inch= 25.4mm, 1 ft. = 304.8mm, 1 gallon/m=3.785L/m. Water velocity should not be greater than 2.438m/s at valve seat to prevent noise and erosion.
The hose leaks small amounts of water directly to your garden or flower bed''s roots with little waste. Commercial hoses are designed for hot water and heavy-duty continuous use. Hoses should always be used with aient water temperatures, so hot water should only be used in hoses specifically designed for hot water use.
The one thing that gives EPDM rubber an edge is that it possesses a better level of water swell resistance and a larger operable temperature range than neoprene. Ethylene propylene rubber is commonly produced as EPDM sheet rubber, which is used to create gaskets, seals, protective pads, and other various products.

If you need EPDM properties that are different than the ones shown in the chart below, we can reformulate the compound of the EPDM material so that the EPDM rubber specifiions suit your needs. Finding the correct material especially if you are using it for an O-ring seal is important as the rubber can degrade quickly if the material is not compatible with your environment.

For potable water, HDPE was initially limited to cold water service appliions, as early formulations were not strong enough for the high temperatures of hot water systems. Suppliers then developed cross-linked polyethylene (PEX) with superior strength and high temperature performance.
