FAQ – 2 x 2.5" NH Female / 4" NH Male Fire Supply Manifold

What is a supply manifold used for?

A supply manifold combines multiple water inlets into a single outlet. It is used to organize or adapt a fire protection supply system based on the configuration of the network or the equipment to be connected.

What is the difference between NH and NST-NH?

In this context, NH refers to the threading standard used for North American fire hydrant fittings. It is often referred to as NST-NH. When purchasing, it is especially important to verify exact compatibility with the fittings already in place.

Is the check valve important on this type of manifold?

Yes, the check valve helps prevent backflow between connected lines. This is an advantage when two supply lines are connected to the same manifold.

Is this product compatible with Guillemin fittings?

No, not directly. This manifold is equipped with NST-NH fittings. If your system uses Guillemin fittings or another standard, you’ll need to use a compatible adapter.
