Oil Seals
At Daemar Inc., with thousands of oil seals to choose from, we’ll guide you to the correct style, size and material for your oil seal application. Our oil seals are manufactured by JM Clipper and available in Buna-N (Nitrile) rubber, Viton (fluorinated) rubber, EPDM (ethylene propylene diene monomer) rubber, silicone, PTFE (polytetrafluoroethylene) and polyacrylate. We offer a range oil seals in both metric and imperial measurements to fit your needs. Our rotary shaft oil seals will extend the life of your bearing systems while reducing maintenance costs. Aside from allowing your bearings to retain optimal lubrication, our rotary oil seals will keep contaminants out of your system.
We are proud of our 30-year reputation for high quality products and excellent service. We have supplied our competitively priced fluid-sealing products to customers across a wide range of industries, including automotive, oil and gas, green energy producers, food and beverage, pharmaceutical, power generation and marine.

Sealing material types
Nitrile Rubber
Nitrile rubber is the most commonly used material for oil seals. It has a strong resistance to oils, salt solutions, hydraulic oils and gasoline. It can operate at temperatures between -40C and 120C. It should be noted that nitrile rubber has a poor chemical resistance.
Polyacrylate Rubber
This is an acrylic rubber with a better heat resistance than Nitrile rubbers. It can operate at temperatures ranging from -20C and 150C. This material should not be used with water or temperatures below -20C. Polyacrylate is a good choice for high surface speed environments.
Silicone Rubber
Functioning in temperatures as low as -50C and as high as 180C, silicone rubber oil seals are unsurpassed in their tolerance to heat and cold. They have a high lubricant absorbency, which minimizes friction and wear making it the choice for crack shafts seals. Silicone, however, has a poor hydrolysis resistance. It is not the material of choice for oxidized or hypoid oils.
Fluorinated Rubber (Vitron)
This rubber has the best resistance to chemicals and a superior performance at high temperatures. It is also the highest cost.
