Adaptor was founded in 1976 by water and sewer contractors with a mission to solve two frequently-encountered problems in the industry:

  • The inability to properly key a valve because of a shifted valve box
  • The problem of inflow and infiltration into sanitary and storm manholes

Adaptor’s industry-leading valve box stabilizers take the mystery out of finding the operating nut when you need to key a valve. Our stabilizers – manufactured for all gate and butterfly valve types and sizes – are designed for easy, safe installation.

All of our valve box stabilizer products eliminate valve box shifting, offering stability you can rely on from the day of installation and for years to come. Our products are made in the U.S.A., and we proudly stand behind every product we manufacture.
