Groco PNC-1250 Bronze Pipe Nipple with Check Valve 1-1/4 Inch

The Groco PNC-1250 is a unique cast bronze pipe nipple featuring an integrated internal check valve designed for marine plumbing applications. This innovative design provides an efficient one-way flow control solution that imposes virtually zero flow restriction during normal operation.

Key Features:

• Cast bronze construction for corrosion resistance in marine environments
• Internal check valve opens with less than 1/2 PSI of pressure
• Minimal flow restriction for efficient fluid transfer
• Color-coded bands indicate proper flow direction (green to red)
• 1-1/4 inch NPT pipe thread connections
• Prevents backflow without the need for separate valve installation

The low-opening pressure and streamlined internal design make this an ideal component for marine sanitation systems, bilge systems, and other non-potable water applications where backflow prevention is required without sacrificing flow performance.

Important: NOT approved for use with diesel fuel, gasoline, or in potable water systems. For marine sanitation and grey water systems only.
