Labstrong GSX27LS Cartridge O-Ring is comparable to the Thermo Fisher Scientific Barnstead GSX27. The economical and reliable o-ring is designed for use in the Thermo Fisher Scientific Barnstead B-Pure, E-Pure and NANOpure Quad Style water purification systems. The inexpensive o-ring provides outstanding quality at a significantly lower cost than the competitor’s.The Labstrong Cartridge O-Ring is designed to seal the space between the cartridge and the head piece of the water purification system. The o-ring is designed to prevent leakage between these two connections. Overtime, all cartridge o-rings wear and eventually fail. When the cartridge o-rings fail the water purity will decrease due to water bypassing the cartridge. To prevent this from occurring, Labstrong recommends changing the cartridge o-rings when the cartridges in these water purification systems are replaced. - Made in USA with Global Materials - *Barnstead, B-Pure, E-Pure, Thermo Fisher Scientific and NANOpure are trademarks of Thermo Fisher Scientific.
