Water rotary union SE 6

for oilfor air6-passage

Description
DSTI SE Series 6-passage rotary unions provide six independent fluid passages in a compact, high-pressure-capable design. SE models include standard threaded side connections on shaft and housing and can be ordered with optional axial O-ring face seals for flush mounting. Units are engineered for direct integration with DSTI electrical slip rings for combined fluid and electrical/data transfer.

Key Features

• Six independent flow passages for multiple media routing.
• Compact form factor for space-restricted installations.
• Standard threaded side (radial) connections; optional axial O-ring face seals available.
• Designed for direct integration with electrical slip rings for combined fluid and electrical/data transfer.
