Heli-coil 5407-2 Pipe Thread Repair Kit 1/8-27

Product Description

The HELI-COIL 5407-2 is a pipe thread repair kit designed to restore damaged or stripped 1/8-27 inch pipe threads in metal housings, fittings, and threaded ports. The kit includes everything needed to complete the repair in the field: a drill, a tap, an installation tool, a tang removal tool, and 12 stainless steel wire thread inserts. The insert thread size and external thread size are both 1/8-27 inch, making this a direct thread-restoration solution. Plumbers, HVAC technicians, and pipefitters use this kit to salvage stripped pipe thread ports without replacing the entire component.

This kit is suited for repair work on residential and light commercial systems where 1/8-27 inch pipe thread ports are common - including instrument taps, pressure gauge ports, and small fitting connections. The 12-insert count supports multiple repairs from a single kit, making it practical for service vans and shop benches alike. All required tooling is included, so no separate tap or drill sourcing is needed for standard applications.
