{"product_id":"fmp350-generic-pressure-limiting-valve-350kpa","title":"FMP350 Generic Pressure Limiting Valve 350kPa Universal Water Line Part for Water Filter Systems and Appliance Supply Lines","description":"\u003cp\u003eHigh mains pressure is hard on water filters, plumbed fridges and other appliances with a water connection. The FMP350 is a generic pressure limiting valve that holds the downstream pressure to 350kPa, giving filter housings, fittings and inlet valves a steadier, gentler supply. It is a universal part rather than one made for a single brand, so check the connection size and thread against your plumbing before ordering.\u003c\/p\u003e\n\u003ch2\u003eWhy fit a 350kPa pressure limiting valve?\u003c\/h2\u003e\n\u003cp\u003eMains water pressure varies from street to street and can spike well above what small filter housings and push-fit fittings are designed for. A pressure limiting valve sits in the line and caps the pressure passing through it, so everything after it sees a steady 350kPa or less. Signs a line could use one include filter housings that weep or crack, push-fit joints that keep leaking, loud water hammer when taps close and inlet valves that fail early. Many filter makers state a maximum working pressure, so compare that figure with the 350kPa rating.\u003c\/p\u003e\n\u003ch2\u003ePart details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGeneric pressure limiting valve, part FMP350\u003c\/li\u003e\n\u003cli\u003eLimits downstream water pressure to 350kPa\u003c\/li\u003e\n\u003cli\u003eUniversal part, not tied to one appliance brand\u003c\/li\u003e\n\u003cli\u003eFor water filter and appliance water supply lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable class=\"part-specs\"\u003e\u003ctbody\u003e\u003ctr\u003e\n\u003cth\u003ePressure limit\u003c\/th\u003e\n\u003ctd\u003e350kPa\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eInstalling the valve\u003c\/h2\u003e\n\u003cp\u003eTurn off the water supply and release the pressure from the line before you cut in or unscrew anything. Fit the valve with any flow arrow pointing towards the filter or appliance, and use thread tape or the correct seals on threaded joints. Connecting to a mains supply is plumbing work, so use a licensed plumber where your state's rules require it. Turn the water on slowly and check for leaks.\u003c\/p\u003e\n\u003ch2\u003eQuestions about this part\u003c\/h2\u003e\n\u003ch3\u003eWhat size fittings does the FMP350 have?\u003c\/h3\u003e\u003cp\u003eThe connection size isn't listed on this page, so compare the valve in the photo with your water line, or send us your details through the parts enquiry form and we can confirm the fittings before you order.\u003c\/p\u003e","brand":"Crystal Clear","offers":[{"title":"Default Title","offer_id":44550161170510,"sku":"FMP350_G","price":48.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0768\/3489\/7998\/files\/fmp350-generic-pressure-limiting-valve-350kpa.jpg?v=1792026086","url":"https:\/\/partsshop.com.au\/products\/fmp350-generic-pressure-limiting-valve-350kpa","provider":"My Store","version":"1.0","type":"link"}
