It is machined from solid bronze for corrosion resistance in a marine environment, making it suitable for use with onboard freshwater plumbing where a reliable one-way valve is needed to protect pumps, tanks, and fixtures from reverse flow. The valve has a bronze exterior finish and a compact, two-port body designed to thread directly into standard pipe fittings.\u003c\/p\u003e\u003cp\u003eThe PNC-750 has a National Pipe Tapered (NPT) inlet connection sized at 1 inch and a female NPT (FNPT) outlet connection, giving it two ports total for straightforward inline installation. It measures 2 inches by 1 inch by 1 inch and weighs 0.19 pounds, making it a compact addition to a freshwater plumbing run without adding significant weight or bulk. As a check valve, it is a simple, no-power mechanical component that requires no maintenance beyond periodic inspection for debris or wear.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Groco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e PNC-750\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Check Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Size:\u003c\/strong\u003e 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Type:\u003c\/strong\u003e National Pipe Tapered (NPT)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection Type:\u003c\/strong\u003e FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ports:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 2 inches x 1 inch x 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.19 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Groco PNC-750 check valve do?\u003c\/strong\u003e The PNC-750 is a bronze check valve that allows water to flow in only one direction through a freshwater plumbing line, preventing backflow into a tank, pump, or fixture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size connections does the PNC-750 have?\u003c\/strong\u003e It has a 1 inch National Pipe Tapered (NPT) inlet connection and a female NPT (FNPT) outlet connection, with 2 ports total.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Groco PNC-750 made of?\u003c\/strong\u003e Bronze, with a bronze exterior finish, giving it corrosion resistance for use in marine freshwater plumbing systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow big is the PNC-750 check valve?\u003c\/strong\u003e The valve measures 2 inches by 1 inch by 1 inch and weighs 0.19 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this valve suitable for a boat's freshwater system?\u003c\/strong\u003e Yes, the Groco PNC-750 bronze check valve is designed for use in marine freshwater system plumbing to prevent reverse flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the PNC-750 require any maintenance?\u003c\/strong\u003e As a mechanical check valve with no seals to service on a schedule, the PNC-750 generally only needs periodic inspection to confirm it is free of debris and seating properly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many ports does the PNC-750 have?\u003c\/strong\u003e The Groco PNC-750 has 2 ports: one NPT inlet and one FNPT outlet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the PNC-750 come as a single valve?\u003c\/strong\u003e Yes, the PNC-750 is sold as a single check valve unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the PNC-750 a genuine Groco part?\u003c\/strong\u003e Yes, PNC-750 is the Groco manufacturer part number for this bronze check valve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the PNC-750 be installed in either flow direction?\u003c\/strong\u003e No, a check valve like the PNC-750 is designed to permit flow in one direction only, from the NPT inlet through to the FNPT outlet, to block backflow.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"Default Title","offer_id":49031097549019,"sku":"GRO-PNC-750","price":14.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/619vjzbTlRL.jpg?v=1785208682","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-check-valve-pnc-750-3-4-inch-npt-freshwater-system-valve","provider":"Good Vibes Marina","version":"1.0","type":"link"}
