Dualco Hydraulic Grease Guns

Dualco hydraulic grease gun models are for high-pressure lubricating applications, including ball, gate, and plug valves. These grease guns are easy to operate, efficient, rugged, long-lasting, and rated up to 10,000 PSI. They can be used at high temperatures and in harsh environmental services, including steam, hot oil, hot compressed gas, and offshore platforms.

High-Pressure Grease Guns

The Dualco grease guns can apply standard and specialized lubricants in stick or bulk. These grease guns can efficiently pump highly viscous lubricants, sealants, packings, and cleaners. They are adjustable for pumping liquids and suitable for measured amounts, preventing excess material discharge. Dualco grease guns are also used for hydrostatic and applied testing on pipelines and wellheads.
