Groco PNC-Series Pipe Nipples with Check Valve

Features:

• PNC-Series Check valves can be used to keep a pump primed that is not self priming, on bilge pumps to keep the pump from cycling on and off from water draining back into the sump from the discharge line after the pump shuts off, and are sometimes used in hot water heaters to prevent the heated water from draining back to the tank
  • Boat builders are considering PNCs to keep engines and AC systems primed when the boat is on a lift or trailer
• PNC Nipples are made from PN Series cast bronze nipples
• A Check Valve is placed inside to prevent back-flow in plumbing systems
• Requires virtually no space - the installer is usually plumbing several components together with pipe nipples, and PNC is basically a pipe nipple
• The check valve imposes almost Zero flow restriction and requires less than1/2" PSI to open
• Colored bands indicate the flow direction (Green to Red) and direction is confirmed by the permanent laminated tag
• Use PNCs anywhere the user wants to avoid back-flow (except fuel systems)
