Custom flanges in three (3) easy steps!

Provide us with detailed requirements of your project. We will work from rough sketches, descrip/sites/default/files/tions, or detailed drawings. Our engineering staff will review the requirements of your project and consult with you. We can then provide a quotation within 24 hours in most cases.


Once an order is received, Accu-Glass engineers will review and approve all requirements.  If needed, we'll generate a detailed engineering drawing of the custom assembly and forward an electronic copy for your approval.


Once the approval process has been completed, production will begin at our production facility.  Accu-Glass Products can provide small and large quantities, as needed, with very short lead times.

Below is a small sampling of custom assemblies that we have made for clients in the past.

Custom Assembly

This custom assembly was manufactured because our client needed 18 conductors through a 1/2" through hole.  A 2.75" CF flange was fitted with a 1.33" CF Tee fitting. Two of our 9 Pin subminiature-C type feedthroughs on a 1.33" CF flanges  (PN-100010) were then used on each end. The PEEK connectors were plugged into the feedthroughs prior to closing the assembly.  As you can see by the picture, Accu-Glass Products was able to accommodate the needs of our client. All of this was completed in less than a week.
