When plastic tubing is used with a standard compression fitting, the tubing wall can deform under compression force, leading to leaks or inconsistent seals. This insert sleeve slides inside the tubing end to maintain roundness and structural integrity during tightening. Sold in a 2-pack, this product is lead free compliant, making it suitable for potable water applications where lead-free material requirements apply. Plumbers and pipefitters typically install these during rough-in and fixture connection work.\u003c\/p\u003e\u003cp\u003eThis stiffener sleeve is used wherever 3\/8 inch OD plastic tubing — such as polyethylene or PEX — connects to a compression fitting in residential or light commercial plumbing systems. Common applications include supply line connections to faucets, toilets, ice makers, and water filtration systems. The insert prevents the tubing from collapsing inward when the compression nut is tightened, ensuring a reliable, leak-free joint. The carded retail packaging makes these convenient for service techs to carry as standard stock items on a service truck.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFits 3\/8 inch OD plastic tubing for use with standard compression fittings\u003c\/li\u003e\n\u003cli\u003ePrevents tubing wall deformation during compression nut tightening\u003c\/li\u003e\n\u003cli\u003eLead free compliant for potable water and drinking water system use\u003c\/li\u003e\n\u003cli\u003eSold as a 2-pack for back-to-back connection work or as a spare\u003c\/li\u003e\n\u003cli\u003eCarded packaging for easy jobsite or truck-stock storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/8 inch OD plastic tubing in compression fitting assemblies. Suitable for residential and light commercial plumbing supply line connections where plastic tubing is joined to compression-style fittings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters working on potable water supply lines. Shut off the water supply and relieve line pressure before disassembling any compression fitting. Insert the stiffener sleeve fully into the tubing end before positioning the compression nut and ring. Do not overtighten the compression nut, as excessive force can crack plastic tubing even with the sleeve in place.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubing OD\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTubing Type\u003c\/strong\u003e: Plastic (OD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Free Compliant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ANDERSON METALS CORP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 710559-06\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ANDERSON METALS","offers":[{"title":"Default Title","offer_id":51560817099058,"sku":"710559-06","price":26.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4362639c3995cfefb5b938538041cd29_67c104f7-b5ae-4033-866a-9562126db138.jpg?v=1786458166","url":"https:\/\/voomisupply.com\/products\/anderson-metals-corp-710559-06-compression-stiffener-sleeve","provider":"Voomi Supply","version":"1.0","type":"link"}
