Stainless Steel Sealing Locknuts | Type 316 | Polished Brite Finish | PVC Gasket | NEMA 4X Rated

Stainless Steel Sealing Locknuts are engineered for demanding industrial, commercial, and sanitary environments requiring watertight and oil-tight protection. Built from Type 316 stainless steel, these locknuts offer exceptional corrosion resistance, strength, and long-lasting performance, even in harsh or high-moisture conditions.

Each locknut features a fused PVC gasket that creates a reliable seal against liquids, oils, and contaminants — meeting NEMA 4X standards for rain-tight and watertight applications. The polished brite finish enhances corrosion resistance, cleanliness, and visual appeal, while the robust biting design ensures secure attachment without loosening under vibration.
