Dimensionair-Compatible Air Plugs and Rings

Need a new air plug or air ring for a Dimensionair® readout? We build single-master air tooling that runs on Mahr Federal Dimensionair dial gages, 832 digital Dimensionairs and other single-master readouts of the same amplification. Price any size online in about two minutes, free.

Match your tooling to your readout

Single-master tooling is built for one amplification group. Order the series that matches the D-number on your dial or the tool code on the plugs you already have.

Common questions

Will your air plug work on my Mahr Dimensionair?

Yes, when the series matches your readout's amplification: Single Master Low Amp for D-2500 to D-8000, Single Master High Amp for D-10000 to D-32000, Dual Master for two-master readouts.

Can I mix your plugs with my existing Mahr Federal plugs on the same readout?

Yes, as long as they are the same amplification group. Master each tool on its own setting master, as you do today.

What is the lead time?

Typically 5 to 6 weeks for gages under 2.500″ and 7 to 8 weeks for larger sizes. Ask about expedited delivery.
