Balston 33G12 Housing Filter With Loose Guard

Balston 33G12 is a 1/2" NPT filter housing in the Balston 33G series, built with a 316 stainless steel head and a Pyrex bowl, and it comes with a loose guard. This compact inline unit is designed for filtration of liquids in sampling or analytical workflows and accepts Balston cartridge families LP, M, and X (notably the 100-12 and 100-25 cartridge designations) to suit different impurity levels. Key specifications include 1/2" NPT inlet/outlet ports, overall dimensions of 2.6" diameter by 4.5" long, and an approximate 3 lb weight. The seals are Viton, and the internal components are 316SS, with a maximum operating temperature of 160°F (71°C) and a maximum operating pressure of 100 psi; a differential pressure limit around 60 psi is recommended to protect the cartridge and housing. The 33G12 variant is intended for use with the corresponding cartridge lengths indicated by the 12/25 designations, enabling tailored filtration performance. Common applications include protecting downstream analytical instruments and laboratory equipment from solids in liquid lines, making it suitable for sample preparation, water and chemical filtration in bench-top systems, and inline protection in analytical workflows requiring reliable, compact filtration.
