Engineered to integrate with the MalcoEdge TEMS expander tool, this head enables direct connections by expanding tube ends into smooth, leak-resistant swages—eliminating the need for fittings and brazing in many installations. Built from hardened steel, it delivers consistent performance even in demanding, high-pressure service environments.\u003c\/p\u003e \u003ch3\u003eWhy technicians choose the TEH500\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eDirect connections, fewer joints\u003c\/strong\u003e: Expand tube ends to create snug, leak-resistant swages that connect cleanly without brazing or extra fittings.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e1\/2-inch precision\u003c\/strong\u003e: Tightly controlled expansion ensures uniform swage diameter, reducing the risk of binding and preventing leaks in critical HVAC and refrigeration lines.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eRugged, durable construction\u003c\/strong\u003e: Hardened steel construction stands up to daily use in busy service bays and field installations, maintaining accuracy over time.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSeamless compatibility\u003c\/strong\u003e: Designed to work with the MalcoEdge TEMS expander tool, delivering a cohesive system for streamlined workflows.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eLeak-resistance by design\u003c\/strong\u003e: Smooth expansion minimizes surface irregularities that can become leak paths, contributing to long-term performance.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eHow it works with the MalcoEdge TEMS expander system\u003c\/h3\u003e\n\u003cp\u003ePairing the TEH500 with the TEMS expander tool creates a compact, efficient workflow for expanding copper and aluminum tube ends. Technicians can prepare tubing, expand to the precise 1\/2-inch dimension, and mate directly to compatible fittings or adaptors without torch work or brazing. This approach reduces heat-related concerns, speeds up service times, and lowers the potential for residue or flux-related issues in critical HVAC loops.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eRetrofits and upgrades in HVAC and refrigeration where space is limited and speed matters\u003c\/li\u003e \u003cli\u003eNew installations that require robust, leak-tight joints without brazed connections\u003c\/li\u003e \u003cli\u003eField service where quick, dependable swages help minimize downtime on cooling or heating lines\u003c\/li\u003e \u003cli\u003eMaintenance scenarios that benefit from repeatable, high-quality expansion shapes to ensure seal integrity\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePractical tips for best results\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eKeep tubing ends clean and free of burrs before expansion to achieve the smoothest swages\u003c\/li\u003e \u003cli\u003eAlign the expansion head straight with the tube axis to prevent asymmetric swages\u003c\/li\u003e \u003cli\u003eInspect each expanded end for uniform diameter and surface finish; rework if any irregularities are detected\u003c\/li\u003e \u003cli\u003eTest joints under appropriate pressure after installation to verify leak-free performance\u003c\/li\u003e \u003cli\u003eStore the TEH500 with other MalcoEdge components in a clean, dry environment to preserve precision\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhat you can expect in the field\u003c\/h3\u003e\n\u003cp\u003eWith the TEH500, technicians gain faster install times and cleaner connections, especially in tight spaces where brazing isn't practical. The hardened-steel build provides dependable long-term durability, while the 1\/2-inch expansion head delivers repeatable results across multiple service calls. The result is a streamlined workflow, reduced heat exposure on sensitive components, and joints that stand up to the pressures of modern HVAC and refrigeration systems.\u003c\/p\u003e \u003ch3\u003eWhy this matters — a clear value proposition\u003c\/h3\u003e\n\u003cp\u003eIn HVAC and refrigeration, the quality of a tube joint directly influences system efficiency and reliability. The MalcoEdge TEH500 addresses common pain points—costly fittings, potential leak paths from brazed joints, and time-consuming field brazing—by enabling precise, leak-resistant swages with direct connections. If you’re aiming for faster service, less heat damage, and dependable performance in copper and aluminum lines, TEH500 is purpose-built to deliver.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Malco","offers":[{"title":"Tube Expanders","offer_id":42729173450800,"sku":"574-TEH500","price":76.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/3883\/0640\/files\/1e7d2f9d-d7e0-4cbc-ad4a-b35796d04da3.png?v=1769538009","url":"https:\/\/usatooldepot.com\/products\/malcoedge-teh500-tubing-expander-head-1-2-inch-expansion-head-for-copper-and-aluminum-tubing-in-hvac-and-refrigeration-applications","provider":"USA Tool Depot","version":"1.0","type":"link"}
