The external threaded connection is the key advantage of this water cap, featuring a standard M16×1.25 thread that can be tightened by hand without tools, reducing installation time and eliminating the need for specialized equipment. Made of 304L low-carbon stainless steel, it has superior resistance to intergranular corrosion compared to standard 304 stainless steel, ensuring no heavy metal leaching into drinking water and complying with RoHS and CE safety regulations. With a flow area of 9.0 cm², it supports a maximum flow rate of 8 m³ per hour, making it ideal for small-scale water treatment systems. The outlet precision of ≤0.2 mm effectively retains fine filter media particles, preventing them from entering drinking water. Its compact design with a cap body diameter of 28 mm fits small filter tanks with limited space, and its service life of over 6 years reduces replacement costs for residential and commercial users.
This quick-install water cap has a total height of 70 mm, with a cap body diameter of 28 mm and a threaded section length of 12 mm. It weighs 120 grams per piece, with an external thread specification of M16×1.25 that fits standard 16 mm water distribution nozzles in small filter tanks. The flow area measures 9.0 cm², supporting a maximum flow rate of 8 m³ per hour at a working pressure of 0.5 MPa. The outlet filtration precision is ≤0.2 mm, effectively retaining filter media particles with sizes above 0.4 mm, including activated carbon, resin, and quartz sand. It can operate within a temperature range of -15℃ to 90℃, making it suitable for both cold and hot drinking water systems. The maximum working pressure is 0.7 MPa, with a pressure drop of less than 0.03 MPa under nominal flow conditions. It is certified to CE and RoHS standards, ensuring compliance with European drinking water safety regulations.
This water cap is widely used in small-scale residential and commercial water treatment systems. In home central water purifiers, it is installed in filter tanks to retain activated carbon and resin media, ensuring clean drinking water for households. In coffee shops and restaurants, it is used in under-sink water filters to improve water quality for coffee brewing and food preparation. In laboratory settings, it is applied in small pure water systems to pretap raw water and protect downstream membrane filters. It is also suitable for office water dispensers and small-scale commercial filtration systems, providing reliable filtration with minimal maintenance. Additionally, it can be used in recreational vehicles and boats, where its quick-install design allows easy replacement of filter components during travel.
