About Zurn Wilkins 3/4" 720A Pressure Vacuum Breaker

Zurn 34-720A Wilkins Pressure Vacuum Breaker 3/4-Inch Assembly This Wilkins Series 720A pressure vacuum breaker assembly is designed for installation on potable water lines to protect against back-siphonage of contaminated water into the potable water supply. Assembly shall provide protection where a potential health hazard exists. The Zurn Wilkins Series 720A Pressure Vacuum Breaker Assembly is used in high hazard applications for protection. Applications are primarily non-potable residential and commercial irrigation systems. Designed for installation on irrigation water lines to protect against backsiphonage of contaminated water into the potable water supply. Assembly shall provide protection where a potential health hazard exists C436-010 1 MA ADAPTER The NIBCO 436 schedule 40 adapter pipe fitting is made of PVC and has a slip connection and a male National Pipe Taper (NPT) threaded connection. This adapter fitting connects pipes or fittings with different end types, diameters, or materials. It has a female slip opening on one end for sliding over a male unthreaded pipe and male NPT threads on the other end for connecting to a female threaded pipe. The slip end connects to pipes with a smooth bore for enhanced flow, and the NPT threads create a tighter seal than straight threads. This schedule 40 (standard wall) fitting is made of PVC for corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC pipes and fittings and is suitable for cold-water pressure distribution systems including irrigation, pool and spa, potable water, and chilled water applications. PVC can be connected to other materials such as steel, copper, or cast iron using transition fittings. This fitting provides superior flow to metal because of its smooth interior finish, which reduces friction and inhibits buildup of materials. This fitting meets American Society for Testing and Materials (ASTM) D2466 and D1784 specifications for quality assurance. Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness). NIBCO manufactures flow-control products for construction, industrial, fire protection, and irrigation applications. The company, founded in 1904, is headquartered in Elkhart, IN, and meets International Organization for Standardization (ISO) 9001 standards for quality assurance.
