Fittings
Fittings and valves for connecting and protecting filter systems, from small tube lines under the sink to whole house connections.
How to choose a fitting
Know what you're joining: tube to tube, tube to thread, or pipe to pipe.
-
Push-fit or threaded?
Quick connect fittings join plastic filter tubing with a push, so you can run a line to a filter, RO unit, fridge or filter tap and change it later. Threaded fittings and valves, such as elbows, tees, sockets and ball valves, connect pipes to housings and pumps.
-
Match the tube size
Push-fit fittings are sized to the outside of the tube, usually ¼", 5/16" or ⅜". Tube sizes must match your connectors, so check the tube on your filter before you order.
-
Match the thread at each end
Threaded fittings need the right BSP size and thread type. Match the tube size and thread type at each end of the fitting, and check the port size on your housing or pump.
-
Control and protect the line
A take-off valve takes water from your cold pipe to feed an under-sink filter. Shut-off valves and tees isolate a line, and pressure limiting valves stop high mains pressure reaching your filters. Tell us what you're connecting and we'll point you to the right part.
