Caps and Plugs

Caps and plugs are easy to discount and overlook. These seemingly insignificant parts of a fire protection system, while small, can lead to system-wide failures when not installed, inspected and properly maintained.

A standpipe fire department connection, left uncapped, is an invitation for small animals to enter, resulting in the build-up of debris and material that can lead to a major blockage and system failure. If readily accessible to the public, an uncapped fire department connection at street level can easily find itself filled with garbage. Both of these scenarios can result in the inability of the sprinkler system to transport water in the event of a fire. Maintaining caps and plugs goes a long way to preventing such failures.

Caps and plugs are available in sizes ranging from 1.5" to 2.5" in diameter and feature quality brass construction for long life, corrosion resistance and durability. Brass caps come with a safety retention chain, have lug pins, and gaskets. A variety of thread specifications are available to meet your needs including NPSH, CSA, BAT, QST and NSZ1.
