This is a washer for 3/4" pipework with an O-ring groove. It is ideal for use when fitting a harbor hose tap to a rainwater collection tank, as the washer holds the O-ring in place and ensures a watertight connection. The washer can easily be screwed down on the adapter and the O-ring can be pushed down into the groove, then the whole unit can be screwed through the hole in the collection container, a further O-ring can be placed on the other side and the garden hose tap can then be screwed onto the unit.
