The Duff-Norton Europe DNCHP Series Rotary Union is an upgrade of the current DNTP Series and is specifically designed to respond to the extreme conditions encountered in Construction and Farming applications. Compared to the DNTP series, the DNCHP Series offers better performance in terms of weight, torque, and reliability in these applications.
Its simple design, using nickel plated carbon steel for corrosion resistance, prevents high pressure hoses from twisting in any weather and temperature condition.
