Lower than normal pressure, pressure variations, and leaks in the 

pumping system can all indicate possible problems with the piston 
seal. Depending on the fluid or mobile phase used, piston seal 
replacement is often necessary after 1000 hours of running time. 

Each replacement seal kit contains one seal, one backup washer, 

one self-flush seal, one non-flush guide bushing, two seal 
insertion/removal tools, and a pad to clean the piston when changing 
the seal.
