JIANZHI pipe fittings are divided into three types by type: heavy, medium and light, according to the surface treatment, there are three types. Galvanized,electro-galvanized, and black. The back nut is able to prevent self-loosening of the fittings. This is a common problem with older pipelines that need replacement. In order to ensure quality, we will 100% test the airtightness of all fittings before packing.
