The Development of Zero-Leak Technology


To custom design an OEM tractor wheel-hub-assembly seal with 100 percent exclusion and abrasion resistance for long life.


A highly reliable polyurethane seal with two lips, designed using finite element analysis (FEA) and extensive in-house testing.


An excluder seal that long outlasts the life of the manufacturer’s warranty with zero contamination and unnecessary wear. It became known as Zero-Leak Technology
