Boshart FIN1436-211 1" Insert x 1-1/2" MPT Poly Pipe Adapter
The Boshart FIN1436-211 is a 1" insert x 1-1/2" MPT adapter fitting designed to transition polyethylene (poly) tubing to male-threaded pipe or fittings in rough-in water system installations. This reducing insert-to-threaded configuration lets contractors and installers step a smaller-diameter poly line up to a larger threaded connection point, such as a pump, tank, or valve, without cutting in a separate reducer and coupling. As a purpose-built transition adapter, it is intended for behind-the-wall, underground, or well/water-system rough-in work rather than finished, visible plumbing.
Key Features
- Trade Size: 1" insert connection on one end transitioning to 1-1/2" MPT (male pipe thread) on the other, allowing a size step-up between poly tubing and a larger threaded connection.
- Insert x MPT Configuration: One end is sized for insertion into 1" poly pipe/tubing and is intended to be secured with a stainless steel clamp; the opposite end is a standard male pipe thread for connecting into female-threaded fittings, valves, tanks, or pumps.
- Reducing Transition Fitting: Purpose-built to bridge two different pipe/tube diameters and connection styles (insert to threaded) in a single fitting, simplifying rough-in runs where poly tubing meets threaded equipment.
- Rough-In Application: Designed for use in well systems, water service lines, and other buried or concealed poly-pipe installations where a threaded transition point is required.
