The 0.75" Insert Plug is a barbed PVC fitting specifically designed for irrigation applications, ensuring a secure, leak-proof connection for various types of pipe and tubing. The primary purpose of this insert plug is to cap off the end of a pipe or tubing, effectively preventing water flow beyond that point—ideal for sections that need to be temporarily or permanently closed off. Commonly used in both residential and commercial irrigation systems, this plug simplifies the installation process while maintaining system integrity.
