■ High-strength transparent tube body can effectively and easily remove air, which can effectively avoid damage to equipment caused by insufficient lubrication
■ High-strength engineering plastics can be restored to their original state after being deformed by a strong impact, with a memory effect, and the cylinder body will not be deformed even after being pressed by a 2T car
■ Never rust, it will not be corroded and rusted even if it is not used for a long time
■ Manufactured with high-strength plastics and inserts.
■The inserts are made of duralumin whose hardness is higher than that of zinc alloy. The double protection prevents the castings from being prone to small pores or interlayers that are easy to exist around the oil outlet, avoiding use Air or oil leakage will occur
