Boshart FGL01105 1/8" Galvanized Steel Pipe Plug Fitting

Boshart FGL01105 1/8" Galvanized Steel Pipe Plug

The Boshart FGL01105 is a 1/8" galvanized steel pipe plug built for rough-in and repair work on threaded galvanized and iron pipe systems. As a solid threaded plug, it is used to permanently or temporarily cap off an unused threaded outlet on a fitting, tee, or manifold, sealing the line while a branch is left inactive or during pressure testing. The galvanized steel construction gives this plug the strength and corrosion resistance plumbers and contractors expect from threaded pipe fittings used in water distribution, gas, and general piping applications where a zinc coating helps guard against rust in damp rough-in environments. At a compact 1/8" trade size, this plug is sized for small branch outlets, gauge ports, drain taps, and test points commonly found on manifolds, boilers, tanks, and threaded fitting assemblies. Contractors and plumbing wholesalers rely on parts like the FGL01105 to keep a stocked assortment of small threaded plugs on hand for finishing off unused ports without having to source an oversized or mismatched fitting. Because it is a standard threaded plug, it installs directly into any mating female threaded connection of the same trade size, making it a straightforward, no-frills solution for capping a line during a job or as a permanent close-off. This is a rough-in trade part intended for professional plumbing, mechanical, and piping installations rather than a decorative or finish-grade component.
