The Brennan PCNY2502 series 90-degree elbow fitting is made of polybutylene terephthalate (PBT) and has tube and NPT female connectors. This 90-degree elbow fitting, or "ell," connects two pipes at a 90-degree angle to change the direction of flow between pipes. It is a push-to-connect fitting that connects to pipes or tubing on one end and has a National Pipe Taper (NPT) female connector on the other. The fitting is made of polybutylene terephthalate (PBT), which is a polymer resistant to solvents, shrinkage, heat, and impact, and it can be treated to increase resistance to UV and flammability. The working pressure for this fitting is up to 290 pounds per square inch (psi), and its operating temperature ranges from -4 to 175 degrees F.Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Push-to-connect compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. 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).Brennan Industries manufactures critical flow components. The company, founded in 1953 and headquartered in Solon, OH, meets International Organization for Standardization (ISO) 9001:2008 standards and its fittings meet Society of Automotive Engineers (SAE) specifications.
