All-Metal Three-Way Pneumatic Tube Junctions for Harsh Environments
All-metal union tee push-to-connect fittings join three pneumatic tube paths without requiring a threaded equipment port. Nickel-plated brass construction makes the fitting suitable for demanding environments and wide temperature conditions.
The push-in connections simplify installation and maintenance while the tee geometry provides a compact branch point in pneumatic distribution circuits.
