Colton Industries - Twin Sphere Connector - AUM Series

Model 'AUM' Threaded Twin-Sphere Connector

Available in sizes 3/4" to 2" NPT union ends for maximum operating pressures as follows:

PMO: (Maximum Operating Pressure): 150 psi @ 225 deg. F.

Vacuum Rating: 16"WC Minimum
Temperature: 14 deg. F.

Rubber connectors allow pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipment.

Materials of Construction:
Union Ends: Galvanized Ductile Iron
Elastomer: Neoprene
Reinforcement: Nylon Fabric
