SQUARE HEAD PLUG, GALVANIZED STEELSolid steel plug with male NPT threads and a square head, used to close off the end of a pipe run or seal an unused outlet. The square head accepts a standard pipe wrench for tight install and removal. Hot-dip galvanized finish resists corrosion in water-service and outdoor applications.
- Male NPT (tapered pipe) threads
- Solid square head engages a pipe wrench for high-torque seating
- Hot-dip galvanized finish for corrosion resistance in water, outdoor, and damp service
- Common uses: water lines, irrigation systems, compressed air, well piping, outdoor plumbing
- Size: 1/8" NPT
Tip: Apply pipe-thread sealant or PTFE tape to the male threads, then tighten with a pipe wrench until snug plus one or two additional turns for a leak-tight seal.
