Description

The Hitachi 891-1213 (VWR catalog number HITA891-1213) is an OEM high-pressure plunger seal (pump piston seal) engineered for Hitachi 600-bar HPLC/UHPLC pump heads. Constructed from high-grade polymeric sealing materials with a integrated flange, this seal offers superior resistance to common organic solvents and aqueous HPLC mobile phases. It creates a tight dynamic seal around the 4.0 mm ceramic plunger piston under operating pressures up to 600 bar in Chromaster 5160 and LaChromUltra L-2160U pumps. Regular replacement of the plunger seal prevents mobile phase leakage, maintains stable delivery pressure and flow accuracy, avoids baseline drift, and protects internal drive components from solvent damage.
