Liquid cartridge housings are a cost-effective and easy-maintenance approach to liquid filtration. Because filter cartridges are generally one-time use, they can be manufactured inexpensively, and sold to the consumer at a competitive rate. Moreover, cartridge maintenance is simple. Easy to remove and replace, liquid cartridge filters are an excellent choice for applications where frequent filter replacement is expected.Liquid cartridge filters systems require o-rings to seal their housings. Because cartridge filters are used for a myriad of applications, the o-rings used in their housings must be as versatile as the housings themselves. Pentair Industrial recognizes this, and manufactures hundreds of types of o-rings for any purpose imaginable. Constructed of Buna-N ®, Silicone, Teflon ® and Viton ®, just to name a few, Pentair’s o-rings can handle the filtration of strong acids, ketones, alcohol, harsh bases, et al. in varying temperature ranges.
