Rain Bird PVC valve fitting 1282-131 - reducing adapter with seal - 1-inch M to ¾-inch M

Reducing adapter for Rain Bird valve manifolds

The Rain Bird RB1282-131 is a compact PVC reducing adapter with seal for the modular Rain Bird valve manifold system. It provides a transition from a 1-inch male thread to a ¾-inch male thread, making it suitable for connecting components with different thread sizes within your irrigation system.

The adapter belongs to the Rain Bird RB1200 Series and can be used when building, extending or adapting an irrigation valve assembly.

Reduce from 1-inch male to ¾-inch male

The RB1282-131 features a 1-inch male thread on one side and a ¾-inch male thread on the other. This allows you to transition from a 1-inch manifold connection to a component with a compatible ¾-inch female thread.

Its compact design allows space-saving installation and is particularly useful for valve assemblies installed inside a valve box.

With seal for a reliable connection

The Rain Bird RB1282-131 is supplied with an O-ring seal. The Rain Bird PVC manifold system uses large O-rings to provide reliable sealing at the designated system connections.

The corresponding system components can be installed by hand and loosened again for maintenance. This makes the system suitable for valve assemblies that may need to be modified or expanded later.

Part of the modular Rain Bird PVC system

The RB1282-131 is part of the telescoping Rain Bird PVC manifold system. The system is designed to simplify the replacement of irrigation valves with different installation lengths without cutting the pipework or adding additional connection parts.

Together with manifolds, tees, crosses, elbows, end caps and other adapters, you can configure your valve assembly to suit the irrigation valves and pipe connections used in your system.
