Overview
The copper threaded filter is a precision filtration device for small-diameter pipelines, constructed from copper alloy and featuring internal threads as its interface. Primarily designed for low-pressure fluid systems including water, oil, and gas, it effectively intercepts fine particles and impurities in pipelines, ensuring the safe operation of downstream components such as faucets, valves, instruments, and small equipment. With its excellent corrosion resistance, reliable sealing performance, and user-friendly installation characteristics, this filter serves as a critical accessory in household water supply systems, small HVAC systems, chiller units, and various instrument pipelines.

Feature
1. Premium material with corrosion and rust resistance: The main body is crafted from brass or stainless steel, offering exceptional corrosion and oxidation resistance. Particularly suitable for aqueous environments, it effectively prevents internal rust, ensuring clean water quality and extended equipment lifespan.
2. Interface standardization ensures easy installation: Featuring universal internal threads (e.g., G1/2 "or G3/4"), it can be directly screwed into the corresponding external threads of pipelines or equipment, requiring no additional flanges or complex tools for quick and simple setup.
3. Compact structure with broad applicability: Its small size facilitates installation in confined pipeline spaces. The system offers a range of filter mesh sizes (e.g., 20 to 100 mesh) to meet diverse requirements, from basic particle interception to relatively fine filtration.
4. Easy maintenance and convenient cleaning: Most designs feature detachable filter cups or screens, allowing the filter to be removed from the pipeline with tools for easy cleaning or replacement of the internal filter element, resulting in low maintenance costs.
5. Economical and durable with reliable sealing: Copper's inherent antibacterial properties and excellent mechanical strength, combined with precision-threaded connections and sealing gaskets, ensure leak-proof joints. This makes it a cost-effective filtration solution for low-flow pipelines.
