Westward 5PXH1 Pipe Tap 1/8"-27 NPT

This Westward 5PXH1 pipe tap cuts NPT threads in pipe and conduit fittings. The semi-bottoming design with four flutes produces clean threads in a single pass. Right-hand threading follows standard plumbing practice. High-speed steel construction resists wear during repeated use.

Suited for plumbers and mechanics threading 1/8

Workers who need taper pipe threads for pressure-tight seals will find this tool effective. Buyers requiring larger diameters or different thread standards must select another tap. The fixed 1/8"-27 specification limits use to that size only.

1/8"-27 NPT thread size

The 27 threads-per-inch pitch and NPT taper profile determine compatibility with matching fittings. Four flutes balance chip clearance and thread finish for this diameter. Semi-bottoming chamfer allows threading closer to the bottom of blind holes.

Questions about this item

Will the 4-flute high-speed steel tap need resharpening or replacement after repeated 1/8"-27 NPT threading jobs?

The high-speed steel construction resists wear during pipe threading; resharpen or replace the tap when the cutting edges dull or chip from extended use.

What limit appears first when running this 1/8"-27 NPT tap continuously through multiple holes?

Chip evacuation in the 4-flute design becomes the limiting factor during sustained threading; clear chips regularly to maintain cutting performance.

How much heat and noise does this bright uncoated tap generate during all-day pipe threading?

The bright uncoated high-speed steel produces moderate heat and typical metal-cutting noise; use cutting fluid to reduce temperature and extend tool life.
