Westlake Pipe & Fittings 1436-012 Male Adapter, 1.25″ MPT x Insert
The Westlake Pipe & Fittings 1436‑012 Male Adapter is a professional‑grade PVC fitting designed to connect threaded components securely to Schedule 40 PVC pipe systems. Featuring a 1.25‑inch male pipe thread (MPT) on one end and a solvent‑ready insert connection on the other, this adapter delivers versatility, durability, and ease of installation in a wide range of residential, commercial, and industrial applications. Whether you’re integrating valves, pumps, gauges, or other threaded equipment into PVC plumbing systems, the 1436‑012 adapter provides a leak‑resistant, long‑lasting solution that stands up to daily operational stresses.
Constructed from premium Schedule 40 PVC, the 1436‑012 adapter offers superior resistance to corrosion, chemical exposure, and environmental wear. PVC materials resist rust, scaling, and degrading compounds that can compromise metal fittings over time, making this adapter well suited for both indoor and outdoor use. Its robust design ensures that it can handle typical water pressures and temperature fluctuations while maintaining joint integrity and functional reliability.
The 1.25‑inch MPT threaded end is precision‑manufactured to match standard female NPT connections, enabling a secure, reliable fit with valves, pumps, meters, and other threaded plumbing components. This threaded connection simplifies system design by reducing the need for additional couplings or adapters and ensures a strong mechanical connection that performs under pressure. When paired with appropriate thread sealant or Teflon tape, the threaded joint provides enhanced leak prevention and durability.
On the other side of the fitting, the insert connection is designed for solvent‑weld installation onto standard 1.25‑inch PVC pipe. Using PVC primer and solvent cement, the insert end forms a permanent, watertight bond that integrates seamlessly into the piping system.
The Westlake 1436‑012 adapter is highly versatile and used in a wide range of applications. In residential settings, it connects water lines to fixtures, pressure gauges, or filtration systems. In pool and spa plumbing, it links pumps and valves to PVC distribution lines. In agricultural irrigation and industrial fluid systems, the adapter serves as a dependable interface between threaded control devices and piping networks. Its lightweight PVC construction also simplifies installation — even in tight spaces — and reduces strain on installers compared to heavier metal adapters.
Precision manufacturing ensures consistent dimensions and reliable performance, meeting industry standards for Schedule 40 PVC fittings. This consistency helps prevent misalignment, leaks, or joint failure, giving contractors and DIY installers confidence that the system will perform as designed.
