Diffley Wright Corporation

Diffley-Wright Corporation was founded in 1963. Our reputation for service began with the personal reputation of Tom Diffley, affectionately known to many as “the Chief.”

Although we are widely known as a distributor of pneumatic automation components, we handle a wide range of product lines in related areas: valves, actuators, sensors, encoders, switches, vacuum pumps and compressors, and a full range of fittings and other components necessary to “put it all together.”

We don’t just sell parts – we spend the time to learn about a customer’s specific needs so that we can offer solutions.

We are proud of our knowledge and experience, and of the fact that we can offer consistent and personal service over the “long haul.” If you call next month, you will be able to talk to the same person that you talked to last month– and that person will not only know the product lines, but make it their business to be familiar with your needs.
