Shaft pu coupling

 O rings Introduction                                                                            

1)O-ring is one of the most common and yet important component in the sealing industry. 2)To ensure the quality, we only offer O-ring from Gapi Group of Italy to meet our aim in providing the best quality products to our customers. Also we offer O-ring kits in both metric and imperial sizes of NBR, High Pressure NBR, Viton and Silicon.

3)Due to the length limitation of the commercial available molded O-ring in the market, we offer various thickness sizes of O-ring cords in NBR, Viton and Silicon as a replacement for long-length O-ring application.

Application                                                                            

1)O-Rings are the most versatile of all seals, as well as simple and low cost. The shape of the O-Ring is a circular torus (O-Shape).

2)It is suitable for both the static and dynamic sealing in almost every field of application within the operating limits and meterial characteristics, provided that these seals are technically designed and applied.

3)Selection of an elastomer (polymers) largely depends on application and physical properties required for an O-Ring.

Couplings 

Couplings are mechanical devices that serves to connect the ends of adjacent objects.
