The 3\/4 NPT thread size is a standard tapered pipe thread, allowing sealed connections within the manifold assemblies and plumbing runs that circulate heat transfer fluid across the heating hose network.\u003c\/p\u003e\u003cp\u003ePer Wacker Neuson HSH 350 manual guidance, couplings in these systems must never be connected or disconnected while lines are pressurized or while heat transfer fluid temperature exceeds 48 degrees C (120 degrees F). Damaged or contaminated fittings must be replaced, and coupling components should be cleaned before and after each use. Replacing a damaged or corroded coupling in the hydronic piping circuit helps maintain proper sealed flow paths in the pressure line and return pipe assemblies.\u003c\/p\u003e\u003cp\u003eCompatible with the following Wacker Neuson models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCH 5000\u003c\/li\u003e\n\u003cli\u003eE1100\u003c\/li\u003e\n\u003cli\u003eHSH 350\u003c\/li\u003e\n\u003cli\u003eHSH350\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43397385388080,"sku":"WACKER-5000168631","price":37.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5000168631.jpg?v=1784034995","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-3-4-npt-galvanized-coupling-5000168631-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
