Selling Precision logo

For 42 Years, Selling Precision have been designing and manufacturing custom hydraulic manifolds. With 7 CNC machining centers running 24 hours, our own 3D CAD/CAM design department and extensive experience in hydraulic circuit designs and valve applications, we can meet your needs. . . economically and on-time!

Selling Precision was formed in 1971, by  Ken and Bill Calcagno. The company has always been in the hydraulic manifold manufacturing business. We have grown steadily and now are one of the premier independent hydraulic manifold manufacturers in the U.S.

Being an "independent" manifold manufacturer means that we are not owned by a valve manufacturing company, which is often the case. We are free to use any manufacturer's valves. Often, in designing a manifold, we will use valves from different manufacturers precisely because no one valve company makes the optimum valve for all situations. This independence allows our customers to select the best valves to serve their needs.
