Spears 1435 Series PVC Tube Fitting, Adapter

The Spears 1435 series tube fitting is designed to connect schedule 40 polyethelene (PE) pipe to threaded pipe conforming to the National Pipe Thread (NPT) standard. Made of gray polyvinyl chloride (PVC) plastic, this adapter features a barbed fitting on one end to tightly seal flexible PE pipe when a hose clamp (sold separately) is used, while the other end has a female NPT connector to connect to threaded pipe. PVC is known for its corrosion resistance and high strength, making it resistant to reactions with acids, gasoline, alcohol, and hydrocarbons. Additionally, this fitting meets ASTM International standards for plastic insert fittings for use with PE pipe (D 2609) and ASTM schedule 40 standards for wall thickness, supporting a working pressure of up to 140 psi. It is also certified by NSF International for use with potable water.

Pipe fittings are crucial components used for connecting, terminating, controlling flow, and changing the direction of piping in various industries. When purchasing pipe fittings, it is important to consider the application, as this will impact the material type, shape, size, and required durability. Fittings are available in threaded or unthreaded varieties, as well as in many shapes, sizes, styles, and schedules (pipe wall thickness). Spears Manufacturing, a company founded in 1969 and headquartered in Sylmar, CA, produces thermoplastic fittings and valves for fluid, drain, waste, and vent systems, meeting the International Organization for Standardization (ISO) standard 9001.

Key features of the Spears 1435 series tube fitting include its ability to connect pipes or fittings of different types, connecting to schedule 40 PE pipe on one end and having an NPT female connector on the other. The PVC material provides strength and resistance to reactions with acids, gasoline, alcohol, and hydrocarbons, while the barbed fitting creates a tight seal on flexible pipe when used with a hose clamp (sold separately). In addition to meeting ASTM D 2609 standards for plastic insert fittings, it is also certified by NSF for use with potable water.
