Union Butterfield Series TN1541 General Purpose NPT Pipe Taps, TiN Coated
Straight Flute - Medium Hook
Medium hook for multi-material tapping. Generally used for pipe fittings and couplings in most ferrous and non-ferrous materials. The nominal size of a pipe tap is that of the pipe fitting to be tapped and not the actual size of the tap. NPT threads require the use of a ‘sealant’ such as teflon tape or pipe compound to ensure a tight joint.
