Product Description

WenDong is famous China O ring mechanical seals manufacturer, providing high-quality and low-price mechanical seals.

China O ring mechanical seals WM502 are one of the most frequently used products in sealing applications. The mechanical seal o ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. Static applications of O-rings may include fluid or gas sealing applications in which: 

(1) the O ring mechanical seals are compressed resulting in zero clearance.

(2) the O-ring material is vulcanized solid such that it is impermeable to the fluid or gas.

(3) the O ring mechanical seals material is resistant to degradation by the fluid or gas.
