Cartridge O-Ring

Not yet rated

The LabStrong GSX27LS Cartridge O-Ring is comparable to the Thermo Scientific™ Barnstead™ GSX27. The economical and reliable o-ring is designed for use in the Thermo 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.
