Home of the Durso Standpipe

International orders are welcomed.  The shopping cart will calculate shipping for all of the countries which have ordered from us in the past.  If you have an international shipping calculation problem while completing an order please let us know -- we may need to add shipping rules for your county.

The Durso Standpipes offered here are made using US Pipe fitting standards. These are commonly called Imperial Fittings outside the United States. Metric adapters can be purchased to adapt the Durso Standpipe to metric fittings.

The following sizes are offered:

• 32mm x 1 inch
• 40mm x 1 ¼ inches
• 50mm x 1 ½ inches

The metric adapters are coupling fittings meaning imperial pipe inserts on one side and metric pipe inserts on the other side.

International orders should only use slip style connections.  There is no international standard on threaded connections. There can be differences in the density of the threads, the angle of the threads, depth of threads, etc.
