Boshart FINS10012 1-1/4" Galvanized Steel Insert Coupling Fitting

Boshart FINS10012 1-1/4" Galvanized Steel Insert Coupling Fitting

The Boshart FINS10012 is a 1-1/4" galvanized steel insert coupling built for rough-in plumbers joining polyethylene tubing runs behind the wall or below grade. This insert-style coupling slides inside the pipe bore and relies on a barbed connection secured with a clamp or crimp ring, giving installers a straightforward way to extend or repair 1-1/4" poly lines without introducing threaded joints into the run. The galvanized steel body resists corrosion in wet, buried, or damp rough-in environments where bare steel fittings would otherwise rust prematurely, making this coupling a practical choice for well lines, irrigation supply, and other underground or concealed poly tubing installations.
