The 13mm (1/2") Brass straight hose joiner for the REGIN REGR09 Drain down hose.
And ideal way of extending the 10M Regin drain down hose to another to combine the length of the hose easily.
Has been tested on our Regin Drain down Hose (Pure rubber material) to ensure a flush fitting.
Can also be used to repair existing hoses which then can be rejoined with the REGR65 hose joiner.
If used with any other hose, the R65 joiner may not create a flush seal as it works best with pure rubber and not rubber blend hoses.
