OMEGA offers a variety of products that can be offered in various configurations. To accommodate this, OMEGA has provided a means to enter nonstandard part numbers on its website. To order a "Nonstandard" part number, add the closest "Standard" number to your cart and proceed with the ordering steps. On the final step of placing your order, there will be a Comments/Special Instructions field where you can provide the modified part number and the details of the modification. OMEGA will contact you to provide the correct part number, and verify price and delivery.
