Derrick Garfield County


Founded in 1988 by Dennis Lynch, our good reputation in the industry grew as a reflection of the quality of our equipment and high level of service.  Today, we’re the master distributor, in the Western United States and Canada, for Washington Rotating. We continue to be family owned and operated, maintaining our reputation for excellent equipment and service.  We’re big enough to meet your needs, yet small enough to provide personal service.


Western Diverter’s mission is to exceed our customers’ expectations by supporting drilling/work over operations with Washington Rotating Control Diverters and associated equipment. We understand that time is your money, and with our professional staff supporting your operation we strive to minimize downtime and repair costs by correct equipment selection, proactive service calls, and educating rig personnel on proper equipment operation and maintenance.

For over 25 years we've been exceeding our customers expectations.


The relationship with our customer doesn't end at the point of sale, our relationship begins at the point of sale.  Once a customer has rented or purchased equipment from us, we are there every step of the way to ensure the best performance. (Your success is our success!)   

Have questions about what part will best suit your needs? We're here to help with that too.
