U-Bolt Mechanical Tees

A U-bolt mechanical tee is a compact branch fitting clamped to a drilled pipe with a single U-bolt, giving a ½” or ¾” female threaded outlet. Its small body makes it easier to connect sprinkler heads in tight ceiling voids.
The store range covers 1½”, 2″ and 2½” main sizes. It is used for sprinkler heads, pressure gauges, air vents and small drain connections.
Main Applications
- Sprinkler head connections
- Pressure gauge and pressure switch points
- Air vent and small drain outlets
- Branches in tight ceiling voids
