タイトルまたは説明

O-rings are ring packings with an O-shaped cross-section. O-rings are placed in groove portions and pressed in moderately before being used to prevent leakage of fluids, such as oil, water, air, gas, and others.  
 There are two types of O-Rings: Static O Ring and Dynamic O Ring. Static Seal is the one which does not move, except for pulsation caused by cycle pressure. Dynamic seals are those seals that are subjected to movement. O-rings are successfully used in both static and dynamic applications.

O-rings are O-shaped ring packings, and are used to seal fluids and dust. DL SEALS has a broad lineup of  shapes, sizes, colors, materials are available upon  coustomers request.
