1-1/2" stainless steel screen filters are designed to fit 1-1/2" connections in drip irrigation systems. Filters are an essential part of any drip irrigation system; they protect your tubing and emitters from becoming clogged with dirt particles and other debris. These particles can build up in emitters, preventing them from watering properly. This can be devastating to your plants, so prevent debris build-up in your emitters with our durable stainless steel screen filters. Our screen filters are available in a variety of mesh sizes.
