Profile: Self-Cleaning Strainer Co. offers manufacturing and distribution of pipe line & valve strainers. Our Paget brand of strainers are designed to successfully protect and increase the life of valves, pumps, traps, pressure regulators, controls & meters. The strainer not only prevents passage of foreign matter in steam, water, air, oil, or gas lines but retains it within the strainer body, where it is removed through a blow-off connector.
