Expansion Joint, Union Type A

The Union-type rubber joint single sphere is composed of a multi-layer scraping nylon curtain cloth, an outer plastic layer composite rubber tube. Solve the traditional rubber takeover due to poor interchangeability and poor sealing factors of easy leakage defects, the use is more reliable At the same time, you can also choose different materials according to different use conditions, with a wider range of applications. Suitable for water, oil, compressed air, etc., is the better product of pipeline inlet and outlet connection
