Aquarium plumbing [Metric]

Metric solid piping is specified by the external diameter of the pipe and socket fittings are measured by the internal size of the plain socket.

Therefore, as an example: 25mm pipe will fit a 25mm elbow.

All socket fittings require to be bonded with a good gap filling solvent.

Please do not use a standard PVC solvent as these are not drinking water safe.

All solvents supplied by ourselves, when dry are safe for Aquarium/Pond use.
