{"product_id":"groco-bronze-pipe-nipple-1-inch-npt-thread","title":"Groco Bronze Pipe Nipple, 1 Inch NPT Thread","description":"\u003cp\u003eThis Groco bronze pipe nipple is a short, fully-threaded connector fitting sized for 1 inch NPT (National Pipe Thread) plumbing runs. It is designed to join two threaded fittings, such as a seacock, strainer, valve, or hose adapter, into a single continuous line, and is commonly used in below-waterline thru-hull plumbing systems where a corrosion-resistant, marine-grade connector is required. The nipple is built in bronze with a bronze exterior finish, giving it strong resistance to saltwater corrosion compared to standard plated-steel or plastic hardware, making it suitable for long-term use in wet bilge and below-waterline environments. Its compact dimensions of 3 x 2 x 2 inches allow it to fit into tight plumbing runs without requiring extra clearance. As a standard 1 inch NPT nipple, it is compatible with any fitting, valve, seacock, or adapter that uses a matching 1 inch NPT female thread, making it a straightforward drop-in connector for repairs, replacements, or new plumbing installations. Because it is a generic threaded connector rather than a model-specific replacement part, it is not tied to a particular engine or boat model and instead fits based on matching thread size and 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 PN-1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Nipple\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\u003eItem Dimensions:\u003c\/strong\u003e 3 x 2 x 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 742985143654\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does this pipe nipple use?\u003c\/strong\u003e The Groco PN-1000 pipe nipple is threaded for 1 inch NPT (National Pipe Thread) connections on both ends.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the PN-1000 pipe nipple made from?\u003c\/strong\u003e It is made from bronze with a bronze exterior finish, which resists corrosion in saltwater plumbing environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this nipple fit my seacock or strainer?\u003c\/strong\u003e Yes, as long as the seacock, strainer, valve, or fitting has a 1 inch NPT female thread, the Groco PN-1000 nipple will thread in and connect the two components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the PN-1000?\u003c\/strong\u003e The Groco bronze pipe nipple measures 3 x 2 x 2 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the PN-1000 pipe nipple weigh?\u003c\/strong\u003e This Groco fitting weighs 0.38 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this nipple compatible with plastic or PVC thru-hull fittings?\u003c\/strong\u003e Yes, the Groco PN-1000 uses a standard 1 inch NPT thread, so it can be threaded into any fitting with a matching 1 inch NPT female thread regardless of the mating fitting's material.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs a pipe nipple the same as a hose barb?\u003c\/strong\u003e No, the PN-1000 is a fully-threaded nipple designed to connect two threaded (NPT) fittings, not a barbed fitting for hose clamping.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this fitting typically used for?\u003c\/strong\u003e The Groco bronze pipe nipple is typically used to join threaded plumbing components, such as a seacock, strainer, or valve, in below-waterline marine plumbing systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this part come with any additional hardware?\u003c\/strong\u003e The listing covers the Groco PN-1000 bronze pipe nipple itself; no additional hardware is specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the PN-1000 specific to a certain boat model or engine?\u003c\/strong\u003e No, the PN-1000 is a generic 1 inch NPT bronze pipe nipple, so it fits based on matching thread size rather than a specific boat model or engine.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"Default Title","offer_id":49031097385179,"sku":"GRO-PN-1000","price":13.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/61YmqTsDPXL.jpg?v=1785208678","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-pipe-nipple-1-inch-npt-thread","provider":"Good Vibes Marina","version":"1.0","type":"link"}
