This water cap's key advantage is its compact plug-in design, which requires no tools for installation, solving the problem of complex assembly in small-space filtration equipment. Made from food-grade 304 stainless steel, it complies with FDA standards, ensuring no harmful substances leach into filtered water, eliminating the risk of plasticizer contamination from traditional plastic water caps. The 0.25mm filtration precision effectively intercepts fine sediment and particles while maintaining smooth water flow, meeting the filtration requirements of household water purifiers. Equipped with a silicone gasket, it provides reliable sealing, preventing water leakage during operation. Its sturdy 304 stainless steel construction resists deformation, offering longer service life compared to plastic alternatives.
The compact water cap has an overall height of 45mm and a diameter of 30mm, made from 1.0mm-thick food-grade 304 stainless steel. The plug-in installation size is 30mm, compatible with most small filter and under-sink water purifier interfaces. The filtration precision is 0.25mm, effectively intercepting fine sediment, rust, and other particles in tap water. The flow rate range is 10-15L/min, meeting the water demand of household kitchen use. It can withstand a maximum working pressure of 1.2MPa, adapting to normal household water pressure fluctuations. The temperature resistance range is -10°C to 100°C, suitable for cold and warm water filtration. The silicone gasket is 1.0mm thick, with good elasticity and sealing performance, ensuring no water leakage. The total weight of the water cap is approximately 60g, lightweight and space-saving.
This compact plug-in water cap is widely used in small-scale water filtration equipment, including household under-sink water purifiers, countertop water filters, and portable travel water purifiers. It is also suitable for laboratory small-scale filtration systems, such as sample pre-treatment filters and small-scale liquid purification units. In these devices, it serves as a water distribution/collection component, ensuring uniform water flow and efficient particle interception, improving filtration efficiency and extending filter element service life. Its tool-free plug-in design makes it easy for users to replace and maintain, reducing after-sales service costs. Additionally, its food-grade 304 stainless steel material makes it ideal for residential drinking water filtration, ensuring water safety and health.
