Taiwan's imports of rubber O-ring rubber imported from Taiwan Wal supply top O-ring advantages: 1. Rubber O-ring sealing performance, working life and high dynamic pressure seal working life than conventional rubber seal products 5-10 times higher, up to a few times, you can seal the substrate with life under certain conditions. 2. The rubber O-ring friction is small, dynamic and static friction equal "0" shaped rubber ring friction 1 / 2-1 / 4, eliminate low-speed, low pressure moving "crawling" phenomenon. 3. The high abrasion rubber O-ring sealing surface worn with automatic elastic compensation. 4. A rubber O-ring good self-lubricating properties. Can be used for oil-free seal. 5. A rubber O-ring structure is simple, easy to install. 6. A rubber O-ring Working pressure: 0-300MPa; Working speed: ≤15m / s; Working temperature: -55-250 degrees. 7. A rubber O-ring Applicable medium: hydraulic oil, gas, water, mud, oil, emulsion, water - glycol acid. Imported rubber O-ring Common Application: rubber O-ring for installation on a variety of machinery and equipment, at a specified temperature, pressure, and various liquid and gaseous media, at rest or in motion for sealing effect. In the bathroom, marine, automotive, hardware, electronics, toys, electronics, aerospace equipment, machinery, and a variety of instruments, large-scale application of various types of sealing elements. Rubber O-ring is mainly used for static seals and reciprocating seals. For rotational movement of the seal when limited to low-speed rotary sealing device. Rubber O-ring is usually installed on the outer or inner circle from the seal section is rectangular trench. Rubber O-ring in the oil, acid, wear, erosion and other environmental chemistry still play a good sealing, damping effect. Therefore, the rubber O-ring hydraulic and pneumatic drive system most widely used a seal. Taiwan's imports in the selection of the O-ring when the hardness of how to choose: the hardness of the rubber O-ring choice is more important. If a pump-turbine power station hardness of 70 (Shore) seals, often flaking, even transection, after using 85 ~ 90 (Shore) seal, the desired effect. Low hardness, easy to install, but prone to peeling, installation damage, extrusion or pressure explosion. Hardness too inconvenient to install. Usually a rubber O-ring hardness 40 ~ 90 IRHD, but in general the use of 70 IRHD is more appropriate for the silicone rubber is the exception, the general use of 60 IRHD.
