Constructed from lead free brass, this stiffener is inserted into the end of the tubing before a compression nut and ring are applied, preventing the tubing wall from collapsing under compression and maintaining a reliable seal. It is rated for a maximum working pressure of 400 psi, making it appropriate for residential and light commercial water supply lines. Plumbers and pipefitters install this component as a standard prep step when working with flexible CTS-compatible tubing.\u003c\/p\u003e\n\u003cp\u003eThis stiffener is used in compression fitting assemblies where tubing end integrity is required for a leak-free connection. It is suited for potable water supply applications and is compliant with lead free material requirements commonly mandated by plumbing codes for drinking water contact. The Tube x NPT end configuration supports connections transitioning from tube to threaded pipe fittings, a common arrangement in residential water supply, fixture supply lines, and light commercial plumbing rough-in work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead free brass construction meets code requirements for potable water contact applications\u003c\/li\u003e\n  \u003cli\u003eRated to 400 psi maximum working pressure for reliable service in pressurized water systems\u003c\/li\u003e\n  \u003cli\u003eCTS insert design prevents tubing wall collapse under compression fitting load\u003c\/li\u003e\n  \u003cli\u003eTube x NPT end connections accommodate transitions from flexible tubing to threaded fittings\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.01 pounds, suitable for tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert stiffener for use with standard CTS compression fittings on flexible copper tube size tubing in residential and light commercial plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters. Shut off the water supply and relieve system pressure before disassembling any compression fitting. Insert the stiffener fully into the tubing end before seating the compression ring and nut. Do not overtighten compression fittings, as this can damage the tubing or distort the stiffener. Work should conform to applicable local plumbing codes and IPC standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead Free Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: CTS Insert Stiffener\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Tube x NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: ANDERSON METALS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 730561-03\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ANDERSON METALS","offers":[{"title":"Default Title","offer_id":51720999665970,"sku":"730561-03","price":16.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af3f9e2789542c056fd38e9a14acde46_a81c7f03-1ddd-45c7-9028-50bbb7a654f1.jpg?v=1788572089","url":"https:\/\/voomisupply.com\/products\/anderson-metals-730561-03-cts-insert-stiffener-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
