RIF (Resin Impregnated Fiberglass) Silicone Rubber Wall Bushing is a new product recent years, but it has good performance in running. So it becomes popular.

It is also a dry type condenser type wall bushing.


Our silicone rubber material adopts the exported material (Dow corning), and LSR process. Colorful sleeve depend on customer request, and also can apply for the high pollution area


We can customize bushing for you, including the special size, special shed colors, the replacement project; NEMA Standard, CT accommodation or other details. We can do what you want. 

Bushing meets IEC 60137 standards, ANSI, or other international standards.
