    Products Feature

    1. Simple and compact structure, easy to install.
    2. Excellent sealing performance, can effectively prevent medium leakage.
    3. Strong bearing capacity, can be applied to the working environment under high pressure conditions.
    4. Long service life, can meet the requirements of long-term stable operation.

    What type of union?

    There are three type socket and threaded,welding.

    How to install union?
