Product Description
different sizes translucent silicone rubber o ring
Silicone rubber seal or Silicone rubber oil seal is characterized by high thermal resistance and can withstand temperatures ranging from –70 to +160 °C (–90 to +320 °F). Silicone rubber absorbs lubricants, thereby minimizing friction and wear. GUIDE silicone rubber seals are particularly suitable for applications with very low or very high temperatures and for low-friction sealing of bearing arrangements. They are not very resistant to oxidized oils or certain EP additives and should be protected against abrasive substances. Sealing lips made of silicone rubber should not be exposed to dry running.
Production Inspection:The production process of the product inspection personnel timing semi-finished product inspection, ensure the quality of the rationality of technology, defective rate control in a reasonable range.
Standard O-Ring Material Applications
We offer the following six standard rubber materials in a range of durometer hardnesses to satisfy practically any service condition:
Viton / FKM O-Ring: Fluorocarbon exhibits exceptional resistance to chemicals, oils, temperature extremes (-13°F to +446°F), low compression set, low gas permeability and excellent aging characteristics. Applications include: aircraft engines, automotive fuel handling systems, and chemical processing industries. FKM is also suitable for high vacuum applications. It is not recommended for exposure to ketones, alkalis, and Skydrol? fluids. Custom compounds are available with improved chemical and low temperature resistance.
Nitrile / NBR O-Ring: Nitrile (Buna-N) is the most widely used elastomer due to its excellent resistance to petroleum products, operating temperature range (-40°F to +257°F) and one of the best performance-to-cost values. It's an ideal material for aerospace, automotive, propane and natural gas applications. Special Hydrogenated Nitrile (HNBR) compounds can improve resistance to direct ozone, sunlight, and weather exposure while increasing temperature range to +300°F.
Ethylene-Propylene / EPDM O-Ring: EPDM has outstanding resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight (-40oF to +275oF); but it is not recommended for gasoline, petroleum oil and grease, and hydrocarbon environments. This popular rubber compound is usually the first choice for low torque drive belt applications.
Fluorosilicone / FVMQ O-Ring: Fluorosilicone (-75o to +400oF) combines the good high and low temperature stability of silicones with the fuel, oil, and solvent resistance of fluorocarbons. FVMQ is unparalleled for aerospace fuel systems, auto fuel emission control systems and to meet or exceed government, military, aerospace, automotive, industrial and commercial specifications. However, due to relatively low tear strength, high friction and limited abrasion resistance of these materials, they are generally not used in dynamic applications. They are also not recommended for exposure to brake fluids, hydrazine, or ketones.
Silicone / VMQ O-Ring: In the Silicone family, you will find compounds which are superior as static seals in extreme temperature conditions. Standard compounds handle operating temperatures -85o to +400oF. Silicone compounds are popular in food and medical applications because they are very clean and do not impart odor or taste. Special Phenyl silicones can be used down to -148°F.
Neoprene / CR O-Ring: Neoprene (-40o to +250oF) is reasonably priced and features good resistance to petroleum oils, ozone, sunlight and oxygen aging, relatively low compression set, good resilience and outstanding physical toughness.
