FIP connection provides a secure, leak-resistant transition. The female iron pipe threads on both ends mate with standard male-threaded fittings, nipples, or adapters, making it a versatile choice for retrofit projects, repairs, or new installations in residential and commercial settings.\u003c\/p\u003e \u003cp\u003ePractical scenarios you’ll appreciate include tying into a hot or cold water circuit where a 1-1\/2\" line must be reduced to 3\/4\" for fixtures, appliances, or branch runs. The malleable iron construction delivers strength and resilience against vibration and pressure fluctuations, while the black finish adds a layer of corrosion resistance suitable for typical plumbing environments. With a maximum operating pressure of 300 psi and a temperature rating up to 150°F, it’s designed for standard water services and non-pressurized applications, helping you avoid over-specification on everyday jobs.\u003c\/p\u003e \u003cp\u003eThis product is ideal for:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eBridging 1-1\/2\" mains to 3\/4\" branch lines in water supply runs\u003c\/li\u003e \u003cli\u003eRepairs and retrofits where existing male-threaded components require a compatible reducing coupling\u003c\/li\u003e \u003cli\u003eResidential and light commercial plumbing projects that stay within its pressure and temperature limits\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eInstallation tips to get a reliable seal:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eEnsure threads are clean and undamaged before installation.\u003c\/li\u003e \u003cli\u003eUse appropriate thread sealant or PTFE tape on male threads to promote a tight, leak-free connection.\u003c\/li\u003e \u003cli\u003eHand-tighten and then give a secure final turn with a wrench, taking care not to over-tighten and damage the threads.\u003c\/li\u003e \u003cli\u003eVerify the system is depressurized before installation and inspect for leaks after initial operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Stz Industries","offers":[{"title":"Default Title","offer_id":52185041207570,"sku":"4214839","price":6.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/1024\/8466\/files\/4214839_A.eps_High.jpg?v=1775767106","url":"https:\/\/nationalhardwaregroup.com\/products\/stz-industries-1-1-2-in-fip-each-x-3-4-in-d-fip-black-malleable-iron-reducing-coupling","provider":"National Hardware Group","version":"1.0","type":"link"}
