Not looking to break the bank on a brand new part? We have many salvaged proportioners and other used Graco equipment that may be just what you are looking for. All salvaged parts are priced at 1/3 the cost of new (or less) and are sold as is. Some example equipment listed here, but don't hesitate to call if you don't see exactly what you are looking for.
For salvage parts, call or email us directly with what you are looking for to see if we have the part available.
