Oil Seal is a mechanical components that used to seal oil (oil is the most common transmission system liquid material), It`s isolated the lubricated components with other components, not let the lubricate oil leakage.

Oil Seal is generally divided into single-type and assembly type, assembly type is the skeleton and lip material can be free combination, generally used for special oil seals.
Oil seal can have different names, customary general rotary axis lip seal called oil seal, the static seal and dynamic seal (general reciprocating motion) was called seal parts.
The representative form of oil seal is TC type, is a double lips oil seal with a fully rubber coated and garter spring, generally speaking oil seal refers to TC skeleton oil seal, skeleton oil seal diagram see Figure:
Generally when the oil seal is working ,its lips area temperature is higher 20-50℃ than working medium. Make sure you noted this when you select the oil seal products.
Oil seal operating range is related to its material:
NBR: -40 to 120℃,
ACM: -30~180℃
FPM: -25~300℃
Application:
Any operate case which have liquid lubricants inside and need to connect with outside also, the connect place is required of oil seals.

The first batch of AP1000 regulator spray valve test
Recently, the first AP1000 regulators shower valve (PV63) at Sanmen NPP Unit 1 was assembled at the manufacturer Fisher's factory in the United States to start the test. A total of hydraulic pressure test, valve seat leakage test, packing seal test, action test and other projects, the results pass. According to reports, the regulator spray valve is a nuclear valve, the reactor coolant system is an important pressure control equipment, operating in the power plant through the role of electric heaters to maintain system pressure within the limits. After the test is completed, the first batch of regulator spray valve will be finalized and shipped next month. This article Keywords: valve
