Vented Cap Body: For Service to 10,000 PSI

The Vented Cap Body Grease Fittings are high-pressure industrial components specifically engineered for demanding lubrication services up to 10,000 PSI. They feature a robust positive-flow design incorporating a heavy-duty ball check and spring mechanism to prevent backflow under extreme pressure. Available in standard NPT thread sizes ranging from 1/4″ to 1″, these fittings are constructed from premium materials like 316 Stainless Steel and Chrome Alloy to ensure optimal corrosion resistance and mechanical integrity.
