At Anping County Boli Hardware Wiremesh Products Factory, we specialize in manufacturing high-performance filtration components. Our Cap-shaped Screen for Water Filtration Systems is crafted from premium 316 stainless steel with a precise 0.2mm mesh and 1 inch NPT connection, designed to meet the rigorous demands of industrial and commercial water filtration. With over 25 years of experience since 1998, we deliver reliable solutions that enhance system efficiency and reduce maintenance downtime.
This cap-shaped screen acts as a robust pre-filter or strainer component, effectively removing particulates down to 75 microns. Its dome design provides a large filtration surface area, minimizing pressure drop while maximizing flow rate. The 316 SS material offers superior corrosion resistance, making it ideal for seawater, chemical, and high-temperature applications. Available with customizable diameters and surface finishes, this screen is a versatile upgrade for any filtration system.

Frequently Asked Questions
-
What is the difference between 304 and 316 stainless steel for this screen?
316 SS contains molybdenum, providing better resistance to chlorides (e.g., saltwater) and acidic environments. For most freshwater applications, 304 may suffice, but 316 is recommended for harsh conditions. -
Can I order a different mesh size?
Yes, we offer customization from 0.1mm to 1.0mm opening. Let us know your required micron rating, and we will adjust the mesh accordingly. -
Is the 1 inch NPT external or internal thread?
This cap screen features a male (external) NPT thread, designed to screw into a female pipe fitting. If you need a female thread, please inquire about custom options. -
What is the maximum operating temperature?
316 SS can withstand up to 200°C (392°F) continuously. For higher temperatures, we recommend verifying with our engineering team. -
How do I clean the cap screen?
It can be backwashed with water or cleaned with a soft brush. For stubborn debris, use a mild detergent and rinse thoroughly. Avoid abrasive tools that may damage the mesh. -
Do you offer samples before bulk order?
Yes, we provide samples for evaluation. Please contact us with your shipping address and quantity needed. -
What is the lead time for standard sizes?
For standard 1-inch cap screens, we typically ship within 7-10 working days after order confirmation. Custom sizes may require 15-20 days. -
Can I get a threaded adapter or flange?
While we focus on the cap screen itself, we can suggest compatible adapters or provide the screen with a welded flange upon request.
