What is a slip fitting?

A slip fitting is best described as a smooth wall male or female fitting that is solvent welded to PVC pipe. This type of fitting allows for a secure and leak-proof connection. The term "slip" refers to the way that the fitting slides or slips over the pipe for a snug fit, which is then permanently joined through the use of a solvent adhesive. This connection method is commonly used in irrigation systems because it creates a seamless flow path, minimizing the risk of leaks and maintaining the efficiency of water delivery.

In contrast, a threaded connection is typically used for metal pipes and creates a mechanical joint that can be disassembled. A type of irrigation valve involves specific mechanisms for regulating flow and is not a fitting. Lastly, assembling metal pipes tends to involve methods such as welding or screwing, which do not pertain to the characteristics of slip fittings in PVC systems. Understanding the definition and application of slip fittings is crucial for effective irrigation design and maintenance.
