Custom-designed mining equipment seals and tunnel boring machine seals

Over the past two decades System Seals has developed a proprietary line of the industry’s most robust and reliable sealing systems designed specifically for mining and tunnel boring equipment. These products carry an unrivaled durability able to withstand the harshest environments. Knowing that operating conditions vary greatly, System Seals works closely with every customer to determine the best solution for each application. 

Whether it’s OEM or maintenance and repair, design engineers and material technicians can custom design mining equipment seals and tunnel boring machine seals that substantially outperform standard parts. This is made possible through Systems Seal’s extensive research-and-development laboratory and on-site testing facilities.

All newly designed seals are rigorously tested with the same fluids, pressures, temperatures and speeds used in the field, with results that typically outperform previous products and frequently exceed customer expectations.
