The self-sealing pipe fitting automatically opens upon installation and seals shut when removed, effectively preventing leakage of media from the pipe and eliminating environmental contamination. This design also helps reduce operational costs, safeguards against dust and debris entering the pipe and equipment—thus minimizing mechanical wear—and lowers the risk of accidents. Additionally, the fitting is easy to install, disassemble, and connect, significantly easing labor intensity and saving valuable work time.
