Rain Bird PVC valve fitting 1301-310 - 3-way manifold - 1-inch M

3-outlet manifold for irrigation systems

The Rain Bird RB1301-310 is a compact PVC manifold designed to connect three irrigation valves. Its three 1-inch male connections allow compatible valves with 1-inch female threads to be connected directly. This makes it ideal for creating three separate irrigation zones inside a valve box.

As part of the Rain Bird RB1300 Series, the manifold is particularly suitable for compact valve assemblies and can be combined with additional components from the Rain Bird PVC manifold system.

Telescoping system for easy valve replacement

A major advantage is the telescoping Rain Bird manifold system. It allows irrigation valves with different installation lengths to be replaced without cutting existing pipework or adding additional connection parts.

The appropriate connections can be loosened for servicing or valve replacement. The telescoping design provides the necessary installation space to remove an existing valve or insert a replacement before the connections are hand tightened again.

Easy installation with large O-rings

Large O-rings provide reliable sealing between the manifold components. The Rain Bird manifold components can be hand tightened, and no additional Teflon tape is required on the designated O-ring-sealed connections.

This design simplifies both initial installation and future maintenance while helping to create a clean and organised valve assembly.

For three valves with 1-inch female threads

The RB1301-310 belongs to the Rain Bird RB1300 Series with male valve connections. Its three 1-inch male outlets are designed for compatible irrigation valves with 1-inch female threads.

With three valve connections, the manifold is ideal for irrigation systems where areas such as lawns, planting beds and drip irrigation need to be controlled as separate watering zones.

Frequently asked questions about the Rain Bird RB1301-310

How many irrigation valves can be connected?

The RB1301-310 provides three valve connections and is designed to create an irrigation manifold with three valves or three separately controlled watering zones.

Which irrigation valves are compatible?

The three valve connections each have a 1-inch male thread and are designed for compatible irrigation valves with 1-inch female connections.

How does the telescoping system simplify valve replacement?

The appropriate connections can be loosened during servicing. The telescoping system provides the installation space required to remove or install a valve. This also allows valves with different installation lengths to be replaced without cutting pipe or adding new connection parts.

Do I need to cut the pipe when replacing a valve?

No. The telescoping manifold system is specifically designed to allow compatible valves to be replaced without cutting the existing pipework or adding new components.

Is Teflon tape required for installation?

No additional Teflon tape is required on the designated O-ring-sealed manifold connections. The system uses large O-rings and the appropriate components can be hand tightened.

Can the RB1301-310 be installed inside a valve box?

Yes. The compact three-outlet manifold is particularly suitable for creating an organised three-zone valve assembly inside a sufficiently large valve box.
