The Shimadzu Low-Pressure Valve Stator Packing is a replacement sealing component associated with the low-pressure valve in compatible SIL-30AC, SIL-30ACMP and SIL-40 autosamplers. Packing helps maintain the intended seal at the stationary valve interface as liquid moves through the selected low-pressure flow path. Wear, compression damage or contamination at this interface can contribute to solvent leakage, impaired sample aspiration or unreliable valve switching. During maintenance, examine the mating stator and rotor surfaces and replace damaged sealing material with the correctly matched packing. Depressurize the liquid chromatography system and remove residual solvent before dismantling the valve. Reassemble components without introducing particles into the sample flow path and verify priming, leak tightness and injection performance before returning the instrument to service. This is stator packing rather than a complete low-pressure stator, a high-pressure valve seal or an injection loop. The precise installation procedure depends on the autosampler generation and valve configuration.
