Eaton Specification Sheet - NPL50500 316SS
316 stainless steel provides superior corrosion resistance, extending service life and reducing maintenance costs in chemical, coastal, and food processing environments. This material choice translates to lower total cost of ownership and fewer unscheduled outages. The 1/2" x 5" size standardizes installations across projects, speeding procurement and simplifying inventory management while ensuring compatibility with common fits and locknuts. Rigid/IMC conduit compatibility delivers robust performance under vibration and outdoor exposure, improving reliability in outdoor enclosures and factory floors. NEC/CEC compliance and UL listings remove ambiguity during inspections, supporting faster approvals and safer installations. Lightweight handling (0.306 lb per unit) aids on-site maneuvering and reduces installation fatigue during large sweeps. Clear cataloging (NPL50500 316SS) and UPC support traceability and batch-level quality control. These features collectively reduce field rework, improve uptime, and align with best-practice standards for stainless steel conduit fittings.
