PVC Joiner

A simple mold made from MDF disks allows a heated piece of PVC pipe to be stretched to form a PVC joiner.

Quick tip: If you leave the PVC to cool on the mold, you will find it difficult to remove. Taking it off hot means there will be some contraction as it cools. To allow for this, make the mold diameter 2mm larger than the pipe you wish to join.

Quick tip: To glue the pieces together you could use plumbers solvent glue, but it gives you zero working time and is intended for a tapered joint. It is better to use quick setting epoxy. Use masking tape on the inside surfaces to keep things clean.

 

The same process applied to a 6 inch port

If I lived in the States, where 6 inch ports have been hard to get, I could probably make a few dollars out of these....
