NPT Tap 1/4-18

The ALLSTAR PERFORMANCE NPT Tap 1/4-18 is a right-hand thread cutting tap designed for creating internal threads in 1/4-18 NPT (National Pipe Thread) specifications. This single tap delivers precise thread formation for fluid and gas line applications common in automotive, industrial, and hydraulic systems where NPT port connections are standard.

The 1/4-18 NPT specification indicates a 1/4-inch nominal pipe diameter with 18 threads per inch, a tapered profile that creates a self-sealing mechanical wedge when properly installed. Right-hand threading follows standard convention for the vast majority of applications. The tap's compact dimensions—measuring 4 inches in length with a 0.65-inch diameter—make it suitable for hand operation or machine mounting in confined spaces where thread cutting is necessary. At 0.17 lbs, it integrates easily into tool kits and portable machine setups.

This tap is essential for technicians and fabricators who need to establish NPT connections in manifolds, valve blocks, and fluid system housings. Users cutting threads in aluminum, ductile iron, or mild steel benefit from the precision thread geometry that ALLSTAR PERFORMANCE delivers. The product suits field repairs, prototype development, and manufacturing operations where creating NPT ports on demand saves cost and downtime compared to pre-threaded components.

NPT taps demand careful speed control and proper coolant application to avoid breakage and ensure clean thread formation. Buyers should verify compatibility with their cutting fluid and machine setup before use.
