Rain Bird PVC valve fitting 1239-131 - reducing adapter - 1-inch M to ¾-inch F

Reducing adapter for Rain Bird valve manifolds

The Rain Bird RB1239-131 is a compact PVC reducing adapter for the modular Rain Bird valve manifold system. It reduces a 1-inch male threaded connection to a ¾-inch female thread, providing a simple transition between different connection sizes within your irrigation system.

The adapter is particularly useful when components with a ¾-inch male thread need to be connected to a corresponding 1-inch connection within the Rain Bird manifold system.

From 1-inch male to ¾-inch female thread

The RB1239-131 has a 1-inch male thread on one side and a ¾-inch female thread on the other. This allows components with different thread sizes to be connected in a compact installation.

The reducing adapter is suitable for residential and commercial irrigation systems and can be combined with compatible components from the Rain Bird PVC manifold system.

Compact solution for valve assemblies

Its compact design makes the adapter particularly suitable for valve assemblies installed inside a valve box. Instead of combining several individual reducing fittings, the required transition from a 1-inch male thread to a ¾-inch female thread is provided by a single component.

This makes it easy to integrate components with a smaller ¾-inch connection into an existing irrigation valve assembly.

Part of the modular Rain Bird PVC system

The RB1239-131 is part of the Rain Bird PVC manifold system, which includes manifolds, adapters, couplings, elbows and end caps. This allows you to configure your valve assembly according to the irrigation valves and pipe connections used in your system.

Rain Bird specifies a maximum operating pressure of 10.5 bar for the PVC manifold system.
