This Spears clamp-on saddle pipe fitting, in white, with a Buna-N O-ring seal, stainless steel bolts and reinforced outlet, is made of schedule 40 PVC and has an IPS saddle fitting and a female NPT branch connection. This two-piece saddle pipe fitting clamps onto the pipe, and is secured with adhesive (not included) and bolts (included), to create a branch connection with one outlet. The Iron Pipe Size (IPS) saddle sits over a hole that has been drilled into the pipe to create the new outlet, and the outlet is sealed with a buna-nitrile (also called Buna-N) O-ring. Buna-nitrile has high tensile strength; abrasion, tear, and compression set resistance; and compatibility with a variety of fluids such as petroleum and hydrocarbons. The saddle clamp bolts are stainless steel for resistance to scaling and corrosion. The branch outlet has stainless-steel–reinforced female National Pipe Taper (NPT) threads for connecting to male threaded pipes or fittings. The NPT threads create a tighter seal than straight threads. This schedule 40 (standard wall) fitting is made of PVC (polyvinyl chloride) for corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with schedule 40 PVC pipes and fittings. 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. It has a maximum operating pressure rating of 235 pounds per square inch (psi) at 73 degrees F. This fitting complies with National Sanitation Foundation International (NSF)/American National Standards Institute (ANSI) 61 Annex G, NSF/ANSI 372, and conforms with lead content requirements for “lead free” plumbing as defined by California, Vermont, Maryland, and Louisiana state laws and the U.S. Safe Drinking Water Act due to take effect January 2014. This clamp-on saddle pipe fitting is suitable for use in cold-water pressure distribution systems including irrigation, pool and spa, potable water, and chilled water applications.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).Spears Manufacturing produces thermoplastic fittings and valves for fluid, drain, waste, and vent systems. The company, founded in 1969 and headquartered in Sylmar, CA, meets International Organization for Standardization (ISO) standard 9001.
