Your paint sprayer is a serious investment. Keeping it in peak operating condition is essential for long-lasting, reliable performance. JB Piston Seal Liquid (8 oz) is a professional-grade throat seal lubricant designed to protect and prolong the life of airless paint sprayers by reducing wear, friction, and material buildup on critical pump components.
