Titan Usa TT93414TIN Npt Pipe Tap 1-11/2 5 Flute Hss Tin

Product Description

The TITAN USA TT93414TIN is a standard NPT pipe tap designed to cut internal tapered pipe threads in ferrous and non-ferrous materials. Built from high-speed steel with a titanium nitride (TiN) coating, this tap delivers improved surface hardness and heat resistance compared to uncoated tooling. It cuts a 1-11/2 NPT thread profile across 5 flutes with a thread length of 1.75 inches and an overall length of 3.75 inches. Machinists, pipefitters, and maintenance technicians use this tap when threading pipe ports, fittings, and manifolds that require a standard NPT seal.

This tap is suited for production and maintenance machining environments where 1-inch NPT threaded connections are required. Typical applications include threading ports in hydraulic manifolds, pipe flanges, HVAC equipment housings, and plumbing fixtures. The 5-flute geometry supports chip evacuation in through-hole and moderate-depth blind-hole applications. The TiN finish extends tool life in interrupted cuts and abrasive materials.

Key Features

• 1-11/2 NPT thread size for standard tapered pipe thread applications
• High-speed steel construction for toughness across a broad range of materials
• Titanium nitride (TiN) coating improves surface hardness and reduces friction
• 5-flute design promotes efficient chip evacuation during threading
• Thread length of 1.75 inches accommodates standard pipe thread engagement depth
• Series 878 designation for direct replacement sourcing and crib management

Compatibility

Designed as an OEM-style replacement and standard tooling option for any application requiring a 1-11/2 NPT high-speed steel pipe tap with TiN finish.

Installation Notes

This tap is installed by machinists or pipefitters using a tap wrench, machine tapping attachment, or CNC tapping cycle set to the appropriate NPT taper ratio. Use cutting fluid rated for the workpiece material to protect the cutting edges and extend tool life. Secure the workpiece fully before threading to prevent movement and tap breakage. Follow ANSI B1.20.1 thread standards for NPT thread depth and gauge verification.
