The valve uses a National Pipe Tapered (NPT) male inlet connection paired with a female NPT (FNPT) outlet, letting it thread directly into standard pipe runs and fittings without additional adapters. Its compact 3 x 1 x 1 inch footprint makes it easy to fit into tight in-line plumbing spaces common on boats, and at 0.4 pounds it adds minimal weight to a system. The valve body combines a bronze exterior finish with a plastic construction, giving it corrosion resistance suited to marine and freshwater environments. As a single-unit, one-way check valve, the PNC-1000 is intended for straightforward in-line installation on new plumbing runs or as a direct replacement for a worn or failed check valve of the same size and connection type.\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-1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Bronze\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\u003eDimensions:\u003c\/strong\u003e 3 x 1 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Groco PNC-1000 check valve?\u003c\/strong\u003e The PNC-1000 is a 1 inch check valve measuring 3 x 1 x 1 inches overall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of connections does the PNC-1000 use?\u003c\/strong\u003e It has a National Pipe Tapered (NPT) male inlet connection and an FNPT (female NPT) outlet connection, so it threads directly into standard 1 inch NPT pipe and fittings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Groco PNC-1000 weigh?\u003c\/strong\u003e The Groco PNC-1000 check valve weighs 0.4 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the PNC-1000 made of?\u003c\/strong\u003e The Groco PNC-1000 check valve has a bronze exterior finish over a plastic body construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this check valve used for?\u003c\/strong\u003e The Groco PNC-1000 is a one-way check valve designed for in-line installation on marine freshwater plumbing systems, preventing backflow through the line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the PNC-1000 allow flow in both directions?\u003c\/strong\u003e No, the Groco PNC-1000 is a check valve, meaning it only allows flow in one direction and blocks reverse flow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Groco PNC-1000 suitable for saltwater use?\u003c\/strong\u003e The Groco PNC-1000 is designated for freshwater systems based on its intended application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the PNC-1000 be installed without additional adapters?\u003c\/strong\u003e Yes, the NPT male inlet and FNPT outlet on the Groco PNC-1000 allow it to thread directly into standard 1 inch pipe and fittings without extra adapters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Groco PNC-1000 sold as a single unit?\u003c\/strong\u003e Yes, the PNC-1000 check valve is sold as one unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Groco PNC-1000 a genuine Groco part?\u003c\/strong\u003e Yes, the PNC-1000 is a genuine Groco manufactured check valve, not an aftermarket equivalent.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"Default Title","offer_id":49031097516251,"sku":"GRO-PNC-1000","price":22.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/61RgAvsnRtL.jpg?v=1785208681","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-check-valve-pnc-1000-1-inch-npt-pipe-nipple-freshwater-system","provider":"Good Vibes Marina","version":"1.0","type":"link"}
