#32 - Brass Sprinkler Extensions: Essential Information

Posted by Jason Hugo on 12/19/2013 to Fire Sprinkler System Components
Brass sprinkler head extensions are used in a fire sprinkler system to extend fixed nipples (drops) that have been cut too short to place the sprinkler head at the proper working height. They are manufactured to fit both half (1/2) inch and three-quarter (3/4) inch pipe and are available in various lengths to allow for exact placement of the sprinkler head. 

Brass sprinkler head extensions are a convenient and cost effective way to reduce assembly time due to manufacturing or engineering errors, or to retrofit existing systems. They provide good thread-to-thread contact at both the male and female connection. As is true at any time the original design of the system is being altered, be sure to check with local authorities to obtain approval for the modification.

Here at QRFS, we offer both half inch and three-quarter inch brass sprinkler extensions.
