A metric standpipe assembly is comprised of three components attached to a male fitting.

The components are: a Standpipe, Bite Sleeve and Metric Nut. The nut is placed over the Standpipe,

followed by the Bit Sleeve (see illustration below). For DIN light assemblies, a DIN light metric nut is used.

For DIN heavy assemblies, a DIN heavy metric nut is used.

The Bit Sleeve and Standpipe are selected on the basis of tube O.D. required.
