4mm Goof / Blanking Plug
This 4mm goof (blanking) plug provides a quick and reliable way to seal unwanted holes in irrigation systems. It is commonly used to repair incorrectly punched holes in 13mm LDPE supply pipe or to permanently blank off unused 4mm micro irrigation tubing, helping to maintain a leak-resistant irrigation system without replacing pipework.
