Sub Adaptor Inc. uses state-of-the-art-heat treating facilities which rolls each piece of steel separately instead of the batch process heat treat. This allows the steel to have more consistent and uniform hardness on circumference, as well as surface to core.

Sub Adaptor Inc. manufactures only for the water well industry to better serve you, the water well customer. With over 80 years of in-house experience, Sub Adaptor Inc. has the knowledge to quickly identify your thread configuration and manufacture the sub to your required length, ID and OD.
