Full-Circle manufactures extraordinary products. And, we are meticulous in our assembly and testing procedures.

For instance, housings used for swivel joints are pressure tested before being used in the assembly process. Once a swivel is fully assembled, it is again pressure tested using sensitive manometers. The typical swivel is tested at a low pressure, medium pressure, and high pressure. It is rotated during the test. Then, pressure is relieved slowly and the swivel is monitored as the pressure relaxes the seal package.

We are also fully audited by various third party agencies. This includes quarterly unannounced visits from Underwriters Laboratories, a yearly audit process conducted by our Notified Body, TUV, and a yearly audit from our ISO 9001:2015 Quality Management System registrar. We also conduct our own in-house audits; twenty-seven or more each year.

Continuity is important to us. We are very focused on providing consistent quality and continually improving our processes.

The end result is a well engineered and fully tested swivel you can count on that performs to our expectations.
