Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 25 years of experience since 1998. Our Chemical Resistant Filter Screen with Cap, PTFE Coated, 100 Mesh, 1/2" NPT is engineered to deliver exceptional performance in demanding acid filtration applications. With annual export values reaching US$5–10 million and serving markets across North America, South America, Europe, Asia, Africa, and Oceania, we bring global expertise to every product we make.
This filter screen combines a robust stainless steel substrate with a durable PTFE (polytetrafluoroethylene) coating, providing outstanding resistance to a wide range of corrosive chemicals, including strong acids, bases, and organic solvents. The 100 mesh size offers a fine balance between filtration precision and flow rate, while the integrated 1/2" NPT threaded cap ensures easy installation and secure sealing in piping systems.
Designed for longevity and reliability, this product is ideal for chemical processing, pharmaceutical manufacturing, water treatment, electroplating, and laboratory use. Below, we detail its key features, technical specifications, and the tangible benefits it brings to your operations.
Key Features & Advantages
- Superior Chemical Resistance: The PTFE coating forms a non-stick, inert barrier that withstands concentrated acids (e.g., sulfuric, hydrochloric, nitric), alkalis, and solvents, preventing corrosion and extending service life.
- Precision Filtration: 100 mesh (approximately 150 micron opening) efficiently removes particles down to 150 microns, suitable for clarifying liquids and protecting downstream equipment.
- Convenient NPT Connection: The 1/2" NPT male thread on the cap allows direct integration into standard pipe systems, easy to install or replace without special tools.
- Integrated Cap Design: The attached cap provides a secure seal, preventing leaks and contamination, while also facilitating quick cleaning or replacement of the filter element.
- High Temperature Tolerance: PTFE remains stable at temperatures up to 260°C (500°F), making it suitable for hot acid filtration processes.
- Low Pressure Drop: Optimized mesh weave ensures minimal flow resistance, reducing energy consumption in pumping systems.
- Customizable Options: Available in different mesh sizes, connection types, and cap materials upon request to meet specific application requirements.
