Among the supplies needed to install home irrigation, 5 mm threaded connectors, PVC pipe, bleed valves and sprinkler heads should be at the top of your shopping list.

Irrigation systems are essentially lengths of hose or pipe that send water to areas of you yard or garden.

These lines are connected to each other, to valves and to secondary water lines using threaded connectors of various sizes.

PVC pipe is so named because it's made from polyvinyl chloride and  is the type of pipe used in most irrigation systems. PVC pipe is divided into two types – C1, or class system PVC, and SCH, or schedule system.

Each system of PVC pipe is rated via different criteria. Schedule pipe is rated by the thickness of material that the pipe is made from, while, class system PVC pipe is rated by operating pressure.

No matter what the wall thickness, the external diameterIrrigation 5mm Threaded Connectorss of all PVC pipe are consistent – a 5mm irrigation pipe will need 5mm threaded connectors, a 3/4-inch PVC pipe will need 3/4-inch connectors, and so on.

Connectors – or "fittings" – for PV pipe are rated as well. You'll usually see SCH 40 fittings, which are the standard white PVC connectors, and occasionally SCH 80 fittings, which are stronger.

These are usually gray in color. PVC connectors are usually glued onto the PVC pipe, but some PVC pipe has threaded ends, and can take either threaded PVC connectors or threaded steel connectors.

Along with PVC ball valves, elbow joints, three- and four-way connectors and PVC cement for your irrigation, 5mm threaded connectors will be tossed in the basket when you shop for supplies.
