You CAN use plumbing caps from Bunnings - the white PVC high pressure series - and a short length of the pipe they are designed to fit as a joiner.  eg  Holman 50mm Press PVC Cap End but use the smaller BNC connector series at/up to 100W  in lieu of SO239 sockets  /PL259 plugs (also known as UHF series).  eg Jaycar BNC PANEL Socket - SINGLE HOLE MOUNT PS0658, and use PP0650 clamp plug so you don't require a crimp tool.  Alternatively a box like a Jaycar HB6120 will do the job, and gives two options - either a toroidal core or just plain connecting wires inside.

Ideally you should use a 1:1 BALUN at the centre point so that there is less likelihood of radiation from the coax feeder - which does happen as a matter of course when a BALUN is not used.  These can be fitted into one of the sealed ABS boxes like the HB6120 (above) available from Jaycar or the heavier duty similar boxes available from electrical outlets.

Thanks Doug,

Very helpful, the HB6120 box looks interesting will head down to Jaycar this morning and have a look.
