The broad range of Parker Rotary fittings and swivel fittings is used to connect a fixed point with an oscillating, rotating, or moving machine component via a hose. As more and more users are dealing with difficult working conditions, the “Heavy Duty 360°” series has been developed. The combination of the proven and reliable Parker ball bearing with a new design and seal concept results in significant improvements in pressure, temperature and corrosion resistance. In addition, durability and flow properties have also been optimized. Heavy Duty 360° fittings work at a rated pressure of 420 bar. The new seal unit is specially designed to provide continuous, reliable sealing performance in combination with suitability for use at low temperatures. This ensures that the rotary fitting itself will function with ambient and medium temperatures between -40°C and 95°C.
