Industrial Pressure Washing: The primary sealing component for professional-grade power washers used in heavy-duty equipment cleaning. Water Jetting & Hydro-Demolition: Essential for ultra-high-pressure pumps used to cut through concrete or strip industrial coatings. Chemical Processing: Employed in dosing pumps that handle aggressive reagents where zero-leakage is a safety requirement. Oil & Gas Field Services: Used in high-pressure "Triplex" pumps for well-servicing and fluid injection. Reverse Osmosis (Desalination): Critical for the high-pressure pumps that force seawater through membranes in water treatment plants.
