Hertel G127048-S Pipe Tap 1/8-27 Npt 4 Flute Hss

Product Description

The HERTEL G127048-S is a standard pipe tap designed to cut internal NPT (National Pipe Taper) threads in pipe fittings, valves, manifolds, and similar plumbing and HVAC components. Built from high speed steel (HSS) with a bright, uncoated finish, this tap produces 1/8-27 NPT threads using a 4-flute, regular hook geometry. The overall length is 2.125 inches. It is used by plumbers, pipefitters, HVAC technicians, and machinists when threading new ports or re-chasing damaged pipe threads in metallic workpieces.

This tap is suited for threading 1/8-27 NPT connections in residential and light commercial applications. Common uses include threading ports in HVAC manifolds, gas valve bodies, pressure tap locations, pipe nipples, and cast or machined fittings where a standard tapered pipe thread is required. The 4-flute design provides good chip clearance and thread finish in ferrous and non-ferrous materials.

Key Features

• 1/8-27 NPT thread form for standard tapered pipe connections
• 4-flute, regular hook geometry for controlled cutting action
• High speed steel construction for durability in ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose threading
• 2.125 inch overall length for compact access in tight applications

Compatibility

Designed for cutting 1/8-27 NPT internal threads in metallic workpieces including pipe fittings, valve bodies, and machined components that require standard tapered pipe thread connections.

Installation Notes

This tap is installed using a tap wrench or appropriate machine holder by a plumber, pipefitter, or HVAC technician. Always apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Ensure the workpiece is securely fixtured and the tap is started square to the bore before applying cutting force. Follow applicable codes such as IFGC and IPC when threading gas or water service connections.
