History:

The foundation for DUALCO was laid in the 1950s. One of the founders, Lee Reed, came from McEvoy Valves in Houston, Texas. Lubrication Equipment was manufactured under the name of Hypar Instrument Company from 1960 until 1978, when the DUALCO name was established.

 

DUALCO’s primary focus is manufacturing lubrication devices that include products such as Hydraulic Grease Guns, Push Type Utility Grease Guns, and the Squeeze Tube Grease Gun lines. Other manufactured products include Fitting Adapters and Service Tools, Button Head Couplers, Special Fittings and Accessories. Also, Air- and Manual-Operated Bulk Systems, Air/Hydraulic Injection Guns and Skid-Mounted Lubrication Units are manufactured.

 

Some product lines DUALCO manufactures were purchased from competitors and date to the 1940s. New products are continually added, including those under patent protection.

 

All Guns, Couplers, Fittings, and Nozzle Accessories manufactured by DUALCO have a proven history of quality performance and are well suited to meet lubrication requirements for a wide variety of applications. Some of the products DUALCO manufactures have been in use for over 70 years.

 

Whether it is specialty grease, sealant, or packing that is to be applied, or a special hardware application that is needed, DUALCO has the right products. DUALCO has many options from which to build the correct coupler, fitting or nozzle accessory combination for the intended application.
