PVC Tube Fitting Adapter, 1/2 Barbed x NPT Female

The Spears 1435 series tube fitting is a PVC plastic adapter designed to connect schedule 40 polyethelene (PE) pipe to threaded pipe conforming to the National Pipe Thread (NPT) standard. This adapter features a barbed fitting on one end for creating a tight seal on flexible PE pipe when used with a hose clamp (sold separately), and a female NPT connector on the other end for connecting to threaded pipe.

PVC is chosen for its corrosion resistance and high strength, making it resistant to reactions with acids, gasoline, alcohol, and hydrocarbons. It meets D 2609 standards set by ASTM International for plastic insert fittings for use with PE pipe, and also complies with ASTM schedule 40 standards for wall thickness to support a working pressure of up to 140 psi. Additionally, this fitting is certified by NSF International for use with potable water.

Pipe fittings play an important role in connecting, terminating, controlling flow, and changing the direction of piping in various industries. When selecting pipe fittings, it is crucial to consider the application, which will impact the material type, shape, size, and required durability. Fittings come in threaded or unthreaded options, as well as various shapes, styles, sizes, and schedules (pipe wall thickness).

Spears Manufacturing, founded in 1969 and based in Sylmar, CA, specializes in producing thermoplastic fittings and valves for fluid, drain, waste, and vent systems. The company is compliant with the International Organization for Standardization (ISO) standard 9001.

In summary, the Spears 1435 series tube fitting serves as an adapter for connecting pipes or fittings of different types. It is designed to connect to schedule 40 PE pipe on one end and has an NPT female connector on the other. The use of PVC provides strength and resistance to reactions with various substances, and the barbed fitting ensures a tight seal on flexible pipe when used in conjunction with a hose clamp. Meeting ASTM D 2609 standards for plastic insert fittings and being certified by NSF for use with potable water further demonstrates the quality and reliability of this fitting.
