Your feedback
The Model 70 is a multi pass fluid rotary union with over 30 years service as the diving industry standard fluid joint. It is available as a stand alone FRU or combined with electric slip ring and fiber optic rotary unions. Typically configured with up to 12 passes, inter-port mixing is prevented through the use of double seals and an intermediate vent between passes. It has also proven itself in non diving applications such as centrifuge, indexing tables, and floating oil production swivels where product quality is paramount.
The Model 70 is available in several standard port configurations or types as illustrated below. The Model 70 is available with the standard seal technology or with a new low leakage seal option. In its standard configuration, it is rated for 1000 psi [68 bar] at 10 rpm continuous service and up to 30 rpm intermittent service.

1/4, 1/2, 5/8, 1 SAE straight thread o-ring ports standard
Corrosion resistant materials suitable for hot sea water and other harsh chemicals
Rated to 1000 psi [68 bar] at 10 rpm continuous service
