Seals for Irrigation Products

Nitrile and EPDM with a sulfur cure are the most common rubber materials used in the irrigation industry. Nitrile rubber is one of most common elastomers used in O-rings and seals. It offers good physical properties and temperature range at a relatively low cost compared to other types elastomers. Nitrile rubber has a broad temperature range from -40°C [-40°F] to +100°C [+212°F] and also works well with most oils and greases.

EPDM rubber offers good low temperature flexibility, high tensile strength, high tear and abrasion resistance and excellent resistance to ozone, water and oxidation. EPDM’s temperature ranges from -55°C [-67°F] to +125°C [+257°F] but is not compatible with most oils and greases. EPDM is the recommended material for use with water. A Peroxide Cured EPDM rubber compound is recommended for chloramine resistance. Elastomers other than Nitrile or EPDM may be required depending on their exposure to other chemicals. Satori Seal offers a wide variety of elastomers to suit most applications.
