Lang 2573 External Pipe Thread Restoring File Set 3 Pc

Product Description

The LANG 2573 is a 3-piece external pipe thread restoring file set designed to rehabilitate damaged or corroded external pipe threads without cutting new ones. Each file measures 7/16 inches in diameter and 8-7/16 inches in length, offering a comfortable reach into tight service locations. The set covers a wide range of thread pitches: 9, 10, 11, 12, 13, 14, 16, 18, 20, 24, 27, 28, and 32 TPI. Plumbers, HVAC technicians, and pipefitters use this set to restore threaded fittings and pipe ends on-site, minimizing the need to cut and rethread pipe during service calls.

This file set is suited for residential and light commercial plumbing and HVAC work where external pipe threads on iron, steel, or similar pipe materials have been damaged by corrosion, cross-threading, or mechanical impact. The broad TPI range makes it adaptable across NPT and common straight-thread pipe sizes encountered in supply, drain, and gas line service. It is a standard diagnostic and repair tool kept in service vans and shop toolboxes alike.

Installation Notes

Thread restoration files are typically used by licensed plumbers, pipefitters, and HVAC technicians. Before working on any threaded gas, water, or refrigerant line, shut off the relevant supply and relieve system pressure per local code requirements. Use the correct TPI file against the damaged threads and work in consistent strokes to avoid further thread distortion. Follow applicable IPC or IFGC requirements when restoring threads on pressurized gas or water piping prior to reassembly and pressure testing.
