Series HPMC Rotary Unions® are designed for higher pressure requirements, available with up to eight ports as standard and are suitable for use in low speed applications for pressures up to 5880 psi (400 bar). Each passage is sealed to restrict leakage between ports. Special configurations are available upon request

Series HSMC is perfect for low pressure applications, up to 175 psi (12 bar) with rotational speeds up to 3,000 rpm.
Feel free to run dissimilar fluids through Duff-Norton Multiport Rotary Unions® as each port is always individually sealed eliminating “crosstalk” between circuits.
DN Sales Australia | Quality Industrial Products
1998 saw a major change in direction for Duff Norton products in Australia. For the previous 25 years they had been well represented by David Brown Gear Industries who enjoyed a majority market position for screw jacks in Australia.
Through international changes in the David Brown Group and their acquisition by the USA giant Textron it appeared that Duff Norton products did not find a place in their new marketing mix.
It was an opportunity for Ron Warman who previously headed up David Brown's standard products division to set up a new company specialising in the vast Duff Norton USA product range while continuing to improve a service to their existing customer base throughout Australia.
From a modest beginning and product knowledge DN Sales Australia have accumulated a sound customer base far beyond that which Duff Norton enjoyed 10 years ago.
As some customers were lost to competitors a whole new raft of names have emerged as advocates not only for the Duff Norton product but very importantly for the service we strive to improve at every opportunity.
The best way of finding out about our claim to good service is to give us a call next time you have a requirement for any of Duff Norton's products .
