The GP
Series 2 Passage rotary unions are commonly used to connect
supply & return lines to rotating equipment. They are suitable
for water, hydraulic, pneumatic and other medias. Many GP Series
products are also available as
RotaRing™ rotary union/slip
ring assemblies.
The GP Series unions are available with
a number of slip ring options for power, signal and data transfer.
The RotaRing™ assembly
is available with an aluminum cover to protect the slip ring
during use in demanding environments.

sizes available upon request |
| Connections Threads: |
NPT threads standard. SAE, BSPP, NPTF, and other thread
options are available. |
| Plating and Coatings: |
Black oxide plating is standard. Anodized, E-Nickel,

Rotating unions are also referred to as:
rotary union, rotary joint, rotating joints, rotary valves,
rotating union, rotary coupling and hydraulic swivel joints.
Examples of applications: Pneumatic
rotary unions for air transfer, Hydraulic rotary joints for
high pressure, Stainless steel rotating unions for corrosive
environments, rotary couplings for coolant water. |
