Walle unique design allows for precise control of frictional forces, resulting in less wear and reduced contamination. Designs for HPLC applications, with operating high pressures ADVANTAGE: Faster throughput Excellent leak tightness
High resistance to wear Improved sample accuracy Good ageing characteristics
Consistent equipment performance
Sustain up to 200MP high pressure
Good self-lubrication and friction performance
STRUCTURE AND MATERIAL: The liquid chromatograph seal is composed of a polymeric material seal and a corrosion-resistant stainless steel metal spring. The sealing ring is installed in the groove, the spring is pressed to form an outward tension, and the sealing lip is pressed against the sealing groove. Since the spring permanently provides the elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the fitting part, thereby forming Sealing from vacuum to low pressure. In addition, the system pressure assists the spring to store energy. The greater the pressure, the more the sealing lip fits the groove, thereby forming a high pressure seal. We can provide variety of materials according to different needs, likes PEEK, PTFE-based material, UHMW-PE and so on.
