Manufactured from 316 stainless steel, this insert reinforces the tubing wall at the compression joint, preventing collapse and maintaining a reliable seal under pressure. It is rated for a maximum working pressure of 150 psi. The insert installs inside the tube end before the compression fitting is made up, supporting the tube against the ferrule load. Plumbers, instrumentation technicians, and industrial pipefitters install this type of component in both commercial and light industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for compression-style tube connections where tube wall integrity is critical, particularly in stainless steel tubing runs carrying liquids or gases. It is used in plumbing, instrumentation, pneumatic, and hydraulic lines where a compression x compression configuration is required. The 316 stainless steel construction makes it appropriate for corrosive or high-purity environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction resists corrosion in harsh or high-purity service environments\u003c\/li\u003e\n  \u003cli\u003eThrough type insert design supports tube wall against ferrule compression load\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections for in-line tube joins\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.05 pounds for easy handling and bulk installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for compression tube fittings requiring an internal support insert in matching tube outer diameter applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers or instrumentation technicians following applicable IPC and instrument tubing standards. Depressurize and isolate the line before disassembling any compression fitting. Insert the support insert fully into the tube end before seating the ferrule and nut. Do not over-torque the compression nut, as this can deform the insert or damage the tubing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Through Type Insert\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 393PSS-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540137935154,"sku":"393PSS-4-4","price":199.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f9011da970a8772d6bd2af29b13a748.jpg?v=1785846786","url":"https:\/\/voomisupply.com\/products\/parker-393pss-4-4-compression-tube-insert-316-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
