Boshart MAS No-Lead Male Insert Adapter, Galvanized

Boshart MAS No-Lead Male Insert Adapter, Galvanized

The Boshart MAS Male Insert Adapter is a no-lead, zinc-plated insert fitting built for rough-in plumbing connections where poly tubing needs to transition to male-threaded pipe or fittings. Manufactured with a galvanized finish for corrosion resistance, this insert-style adapter is designed for plumbers and contractors working with polyethylene or similar insert-compatible tubing systems. This listing covers the Boshart MAS family available in 3/4" and 1" sizes, giving contractors a single source for both common rough-in transition sizes. Each unit ships in bulk packaging of 25 ea, making it a practical choice for contractors stocking rough-in supply for new construction or renovation work. As a no-lead fitting, it is intended for applications where lead-free components are required, and the insert connection style allows for a secure clamp-style joint on the tubing end while the male thread mates to standard female-threaded fittings, valves, or adapters on the opposite end.
