G.A. Murdock has spent many years developing new products for the water conditioning industry to help solve common problems encountered by installers.  We have engineered our products with a focus on ease of installation, compatibility and durability for use with appliances, RO Systems and medical devices.   


All Mur-lok products are manufactured and assembled in the U.S.A. at our factory in Madison, South Dakota.  In recent years we have expanded our production capabilities to include more injection molding machines, automated robotic systems and standardized processes to handle an even broader range of customer-specified tooling and kitting projects.

Please take some time to browse the Mur-lok products available and contact us if you are interested in pricing, specifications, or customized solutions.
