Norgren 5191-88 Panel Mounting Nut Zinc Frl

Product Description

The NORGREN 5191-88 is a zinc panel mounting nut designed for use with intermediate compressed air filters in FRL (filter-regulator-lubricator) assemblies. This hardware component secures the filter body to a panel or enclosure, providing a stable mounting point in compressed air distribution systems. At 0.38 inches in height and a package weight of 0.24 pounds, it is a compact, single-piece fastener intended for installation by industrial maintenance technicians and pneumatic system specialists who require a reliable OEM-style mounting solution.

This panel mounting nut is used wherever an intermediate compressed air filter needs to be fixed to a panel surface, such as in industrial pneumatic control cabinets, machine tool enclosures, or production line air preparation stations. It is appropriate for both new installations and replacement applications where the original mounting hardware has worn or been damaged. Typical installations occur in light to medium industrial environments requiring clean, regulated compressed air.

Key Features

• Zinc construction provides corrosion resistance for compressed air system environments
• Designed specifically for use with NORGREN intermediate compressed air filters
• Compact 0.38-inch height suits tight panel mounting spaces
• Single-piece hardware — no additional components required for panel mounting
• OEM-compatible replacement for existing FRL panel mount installations

Compatibility

Designed for use with NORGREN intermediate compressed air filters as a panel mounting accessory in FRL assemblies.

Installation Notes

Installation is typically performed by industrial maintenance technicians or pneumatic system technicians. Before installation, de-pressurize the compressed air line completely and verify zero system pressure before handling any FRL components. Thread the nut onto the filter body and tighten by hand before applying a wrench — avoid overtightening zinc hardware to prevent thread damage. Follow applicable site safety procedures and pneumatic system lockout/tagout protocols during service.
