This fitting threads into the feeder body (1\/2\" male pipe thread)\n    and provides a secure, right-angle connection to the feeder tubing line. It’s commonly replaced when the original fitting\n    is cracked, leaking at the threads, or no longer seals tightly on the tubing.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003e90° elbow fitting\u003c\/strong\u003e for clean routing of feeder tubing in tight equipment pads.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1\/2\" MPT (NPT) threaded connection\u003c\/strong\u003e to the feeder body or related plumbing port.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompression nut included\u003c\/strong\u003e to clamp and seal the feeder tubing.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHelps stop leaks\u003c\/strong\u003e caused by cracked fittings, stripped threads, or worn compression surfaces.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePentair Rainbow feeders:\u003c\/strong\u003e Model 300-29X (offline), Model 320 (inline), Model 322 (inline)\u003c\/li\u003e\n    \u003cli\u003eAlso used on certain Rainbow feeder accessories\/assemblies that specify \u003cstrong\u003eR172272\u003c\/strong\u003e in the parts list\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eSpecifications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Pentair \/ Rainbow\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e R172272\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 90° tube fitting (elbow) with compression nut\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eThread:\u003c\/strong\u003e 1\/2\" MPT (NPT)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTubing Connection:\u003c\/strong\u003e Compression-style (for feeder tubing)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Sold individually\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eCommon Reasons to Replace\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eWater dripping at the feeder tubing connection or around the compression nut\u003c\/li\u003e\n    \u003cli\u003eCracked elbow body from age, chemical exposure, or winter freeze damage\u003c\/li\u003e\n    \u003cli\u003eStripped\/compromised threads causing seepage at the feeder port\u003c\/li\u003e\n    \u003cli\u003eBrittle tubing that no longer seals properly (often replaced at the same time)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eShut off the pump and relieve pressure before servicing the feeder or tubing lines.\u003c\/li\u003e\n    \u003cli\u003eConfirm the elbow orientation before final tightening so the tubing routes without kinks.\u003c\/li\u003e\n    \u003cli\u003eCut tubing cleanly and square, then fully seat it before tightening the compression nut.\u003c\/li\u003e\n    \u003cli\u003eUse a thread sealant suitable for plastic threads and avoid over-tightening.\u003c\/li\u003e\n    \u003cli\u003eAfter restart, inspect for slow seepage at both the threaded connection and compression nut.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eRelated Products\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=R172274\"\u003eRainbow Compression Nut Only (R172274)\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=R172275\"\u003eRainbow 300-29X Hardware \/ Parts Bag (R172275)\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=R172324\"\u003eRainbow Inline Check Valve, 1\/2\" Tube x Tube (R172324)\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=R172009\"\u003eRainbow Feeder Lid O-Ring (R172009)\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=Rainbow%20300-29X%20parts\"\u003eRainbow 300-29X parts\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=Rainbow%20320%20parts\"\u003eRainbow 320 parts\u003c\/a\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003ca href=\"https:\/\/aquapoolsupply.com\/pages\/search-results-page?q=Rainbow%20322%20parts\"\u003eRainbow 322 parts\u003c\/a\u003e\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eMaintenance Tips\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eInspect feeder tubing seasonally;
