Groco PNC-750 Bronze Pipe Nipple with Check Valve 3/4 Inch

The Groco PNC-750 is a unique cast bronze pipe nipple that incorporates an efficient internal check valve design. This innovative marine plumbing component allows fluid to flow in one direction while preventing backflow, making it ideal for bilge pumps, livewell systems, and various marine plumbing applications.

Key Features:

• Cast bronze construction for durability and corrosion resistance in marine environments
• Internal check valve design imposes virtually zero flow restriction
• Requires less than 1/2 PSI to open, ensuring efficient operation with minimal pressure
• Color-coded bands indicate proper flow direction (green to red)
• 3/4 inch NPT thread connections on both ends
• Compact design saves space in tight engine room installations

Important: Not for use with diesel fuel, gasoline, or other petroleum products. Suitable for water and compatible marine fluids only.

This pipe nipple with integrated check valve eliminates the need for a separate check valve installation, simplifying plumbing layouts and reducing potential leak points. The bronze construction meets marine standards for saltwater applications.
