Constructed from steel with a zinc plated finish and a polypropylene liner, this fitting isolates metallic contact between connected pipe sections while maintaining a reliable fluid path. It measures 4 inches in diameter with a 6 inch overall length and carries a 300 psi pressure rating. The grooved x grooved end connection makes it compatible with standard grooved coupling systems. Licensed plumbers and pipefitters install this fitting in commercial and industrial piping applications where corrosion isolation is required.\u003c\/p\u003e\n\u003cp\u003eThis dielectric nipple is suited for a wide range of installations including potable water, plumbing, mechanical, HVAC, industrial process, fire protection, mining, and oil and gas systems. The polypropylene liner meets ASTM D4140 standards, and the fitting dimensions conform to AWWA C606. It is rated for service between -40 and 110 degrees C, making it functional across both chilled and hot water piping configurations typically encountered in commercial and industrial mechanical rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolypropylene liner isolates dissimilar metals to prevent galvanic corrosion\u003c\/li\u003e\n  \u003cli\u003eSteel body with zinc plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e300 psi pressure rating suitable for commercial and industrial service\u003c\/li\u003e\n  \u003cli\u003eGrooved x grooved end connection for use with standard grooved coupling systems\u003c\/li\u003e\n  \u003cli\u003eTemperature rated from -40 to 110 degrees C for hot and chilled water applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A513, ASTM D4140, and AWWA C606 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in grooved piping systems across water, plumbing, mechanical, HVAC, industrial, fire protection, mining, and oil and gas applications.

Depressurize and isolate the piping system completely before removing any existing fittings or making new connections. Grooved couplings must be properly seated and torqued per the coupling manufacturer specifications. Inspect the polypropylene liner for damage before installation, as a compromised liner will defeat the dielectric isolation function.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel with polypropylene liner\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize A\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize B\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -40 to 110 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Grooved x Grooved\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: ASTM A513\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiner Standard\u003c\/strong\u003e: ASTM D4140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimension Standard\u003c\/strong\u003e: AWWA C606\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e: 7089\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ANVIL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 390216158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ANVIL","offers":[{"title":"Default Title","offer_id":51149630374194,"sku":"0390216158","price":196.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305985934.jpg?v=1778599021","url":"https:\/\/voomisupply.com\/products\/anvil-390216158-dielectric-nipple-4x6-in-grooved-300-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
