Description
This polypropylene threaded plug is designed to seal and blank off unused female threaded outlets within a PP pipework system. It provides a simple and reliable method of terminating pipe runs, spare ports or future connection points without the need for permanent closure.
Manufactured from durable polypropylene, the plug offers excellent resistance to corrosion and chemical attack, making it suitable for use in demanding industrial environments. Its threaded design allows for easy installation and removal, enabling systems to be modified or expanded at a later date if required.
As part of the threaded polypropylene range, this fitting carries a 6 bar pressure rating and is intended for low pressure applications where removable end sealing is preferred.
