Brass Elbows
A brass elbow is a brass fitting with two female-threaded ends that turns a threaded water, heating or air line by 90 degrees. Its machined threads give a clean, tight joint even in small sizes.
It is used in small and medium-bore installations, from washbasin, combi boiler, water heater and meter connections to compressor lines. It is supplied in 12 sizes from 1/8″ to 4″.
Main Applications
- Corner turns in domestic water installations
- Combi boiler, water heater and calorifier connections
- Changes of direction at meter and valve outlets
- Compressed air and compressor lines
- Instrument and control lines (1/8″ – 3/8″)
- Machine cooling water connections
