Adaptor Sockets are used as pipe to male thread couplers

- All Fastlight PVC-U pipe and fittings are high quality, approved by the Water Regulations Advisory Scheme and fully reef safe. 
- All pipe and fittings are metric/imperial and compatible with many other makes of metric/imperial pipe with joints connected using solvent weld glue. 
- This product uses the corresponding PVC Pipe to fit inside of the Adaptor Socket with an imperial male thread on the other end to attach other equipment. It is also possible to fit the spigot end of the adaptor to the next pipe size up by using a Socket Coupler, i.e. a 20mm Adaptor Socket will also fit a 25mm pipe if a 25mm Socket Coupler is used.
