The male NPT threaded end seals into a female pipe-threaded port, while the 1\/2-inch barbed end accepts and retains a hose without the need for additional threaded fittings on the hose side. This combination of connection styles is common in auxiliary oil circuit plumbing where a rigid ported component, such as an oil filter housing or tank fitting boss, must transition cleanly to a flexible hose run.\u003c\/p\u003e\u003cp\u003eBecause this fitting sits at the junction of the auxiliary oil tank and oil filter, any degradation, cross-threading, or sealing failure at this point can disrupt oil flow through the filter circuit. Replacing a damaged or leaking fitting with a properly dimensioned OEM part ensures the connection geometry and thread specifications match the original assembly exactly.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eE3000\u003c\/li\u003e\n\u003cli\u003eE3000 (5100056441)\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":43398904905776,"sku":"WACKER-5100057974","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100057974.jpg?v=1784080951","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-1-2-barb-x-3-8-male-npt-fitting-5100057974-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
