Description
Plastic one-way valve, water stop valve, check valve, pagoda check valve, anti ozone water stop valve, air pump hose check valve
Product Name: Hose Check Valve
Packaging quantity: 3 piece
Product Material: Translucent PP material, colored PE material, food grade
Product Usage: Non toxic, odorless, heat-resistant, suitable for directly connecting hoses to prevent gas and liquid reflux, convenient and fast. The minimum outer diameter marked as the interface at both ends, such as 5-4.5, refers to one end having an outer diameter of 5mm and the other end having an outer diameter of 4.5mm. (The data here all refer to the minimum outer diameter of the joint edge, because hoses have elasticity, and the diameter at the buckle of the pagoda joint will be larger than the diameter at its edge. If the inner diameter of your hose is not among the above, an approximate value can be taken to connect it normally.)
