MNPT X FNPT
MNPT X FNPT
A MNPT X FNPT connector allows the user to convert either a Male NPT connection to a Female NPT connection or convert Female NPT threads to Male NPT connection.
These fittings are NPT threads and will compress against other Female/Male NPT threads creating a tighter and tighter connection. All NPT threads require thread sealant to create a watertight and gas-tight seal between the threads. We recommend using Yellow Gas PTFE Tape because it is rated for gasses and is UL listed and it is NOT recommended to use white PTFE tape because it is not rated for gas service.
National Pipe Taper (NPT)
NPT is a standardized fitting that is commonly used for joining pipes. Due to the tapered threads (wider diameter at the base of the threads, similar to a trapezoid) the male fitting will tighten the further it is threaded into the female. NPT follows the technical standards provided by the American National Standard Pipe Thread standards, often called national pipe thread, which is often where the confusions with NPT arises, as NPT is specifically an acronym that refers to tapered pipe
