Vacuum negative pressure resistant single sphere Rubber bellows expansion joints

The official website of Shanghai Songjiang shock absorber Group Co., Ltd. introduces to you: Vacuum negative pressure resistant single sphere Rubber bellows expansion joints information. Songjiang group provides many vacuum and negative pressure enterprises with single sphere Rubber bellows expansion joints products, which really plays the role of vacuum and negative pressure resistance and helps customers absorb flat rubber joints. The following is a detailed introduction.

Vacuum negative pressure resistant single sphere Rubber bellows expansion joints
