Flush Ring

Mac-Weld flush rings perform even under the most demanding conditions

Our flush ring design is made to accept all flanged pressure transmitters on one side and a standard ANSI flange on the other side in all sizes.

The Mac-Weld flanged flush ring allows the top and bottom outlets to have flanges welded in place. These flush rings allow you to have two different ANSI flange sizes or ratings on opposite sides of the ring. Being approximately 2″ thick, it also allows you to tap the top and bottom. Mac-Weld flush rings are manufactured to accept standard level transmitters or can be customized for your particular application. All flush rings are quality checked and tested to code, prior to being shipped.
