Car care knowledge and precautions

1 air filter
Correct installation of air filters can reduce the wear of parts such as cylinders, pistons, and piston rings. Remind you: Generally, every 5,000 km is cleaned once. Every time you drive 10,000 km, you must replace the air filter.
2 oil filter
The correct installation of the oil filter can prevent impurities from mixing into the engine oil during the use of the internal combustion engine and prevent wear of moving parts and blockage of the oil circuit. Remind you: When replacing the oil, you must change the oil filter at the same time, otherwise it will affect the quality of the oil. The cycle of oil and oil filter replacement is generally 5,000 kilometers.
3 fuel filter
Proper installation of the fuel filter can prevent cylinder wear caused by impurities and moisture mixed in gasoline during storage and filling. Reminder: In order to ensure that the engine is running well, the replacement fuel filter cycle is generally 20,000 km or 1 year. Special advice: "Three filters" must be maintained by professional repair personnel.
Oil common sense:
The common oil grades on the market today are SJ, SL, SM. Among them, SM is the highest grade of lubricating oil in gasoline engines, the most advanced technology used, and the highest lubrication quality. The smaller the number before the viscosity number W, the better the fluidity of the oil. The larger the number after W, the better the protection performance at high temperatures.

TUBING COUPLING

Couplings are used to connect two joints of TUBING coupling or CASING pipe together.

Couplings are short length of heavy wall pipe with the same threads on each end.
EASTSUN manufactures tubing coupling and casing tubing coupling strictly comply with API 5CT latest standard.


The steel coupling is mainly used to connect oil pipes in pil drilling.

This product can be used to connect the shafts of units that are

manufactured separately.

It can fit the misalignment of the shafts or introduce mechanical flexibility.

The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another.

It can also introduce protecyion against overloads.

The steel coupling can be used to alter vibration characteristics of

rotating units.

Pipe coupling is also used to connect drilling par and driven part.
