Fppi 07-450-00 Nst Fire Plug with Chain 2.5 in Brass

Product Description

The FPPI 07-450-00 is a 2.5-inch National Standard Thread (NST) plug with chain, constructed from B124 brass alloy using an all-cast manufacturing process. Designed for fire service applications, the plug features a pin lug design that is compatible with standard fire service pin lug hydrant wrenches. Each unit ships complete with a brass chain and S-type hook for secure attachment to a hydrant or fire department connection. The accurately machined threads and solid brass construction provide reliable, long-term performance in demanding fire protection service.

This plug is intended for use on 2.5-inch NST fire hydrant outlets and fire department connections (FDC) in residential, commercial, and municipal fire protection systems. It is installed by fire protection contractors, municipal water departments, and fire department maintenance personnel. The included chain and S-hook keep the plug secured to the hydrant or FDC body when not in service, preventing loss and reducing debris entry into the connection port.

Installation Notes

Installation and removal should be performed by licensed fire protection contractors or qualified fire department personnel following applicable NFPA standards and local fire code requirements. Always ensure the hydrant or FDC is depressurized and isolated before removing or installing the plug. Use a standard pin lug hydrant wrench to tighten or loosen the plug. Do not over-tighten, as this can damage the brass threads or the hydrant outlet seat.
