Irwin Hanson 1905 1/2"-14 NPT Taper Pipe Tap

The Irwin Hanson 1905 is a high-quality taper pipe tap designed for cutting precise internal NPT (National Pipe Taper) threads in pipe fittings and related applications. This tool features a 1/2"-14 NPT thread specification, where the nominal size corresponds to the pipe fitting being tapped rather than the actual tap diameter.

Key Features:

• 1/2"-14 NPT taper pipe thread configuration for standard pipe fitting applications
• Tapered design at 3/4" per foot to create leak-resistant pipe thread connections
• High-speed steel construction for durability and long tool life
• Precision ground threads ensure accurate, consistent thread cutting
• Ideal for plumbing, pneumatic, and hydraulic installations

This taper pipe tap creates the standard tapered thread profile required for proper sealing in pipe connections. The gradual taper allows the threads to tighten as the fitting is screwed together, creating a mechanical seal that prevents leaks when used with appropriate thread sealant or tape. Sold as a bulk item without retail packaging.
