Product Announcement from Scott Rotary Seals
The new APS series features a 303 stainless steel housing and a hardened 17-4 PH stainless steel shaft. Standard port sizes have 1/8", 1/4", 3/8", and 1/2" NPT connections. Other sizes available upon request. The APS series unions have a unique shaft configuration that consists of individual female tapped passages with an o-ring gland around each for optional flange mounting. There are also threaded holes on the end of the housing for mounting the assembly.
All APS Series rotary unions / rotary joints incorporate durable, long life seals, which are suitable for vacuum and bi-directional pressures up to 7500 psi. All passages are individually sealed to allow use with dissimilar medias. The APS Series rotary unions are commonly used to connect supply and return lines to rotating equipment. They are suitable for water, hydraulic, pneumatic and other media. Many APS Series products are also available as rotary union/slip ring assemblies.
