It’s designed for thin-walled tube sections typical of 1\/4\" lines; hardened or thick-walled tubing may not expand properly. Avoid using on steel or other high-strength metals unless specified by the tool manufacturer.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOptimized for soft copper tubing (1\/4\").\u003c\/li\u003e\n  \u003cli\u003eCompatible with many aluminum HVAC tubes of similar wall thickness.\u003c\/li\u003e\n  \u003cli\u003eNot recommended for hardened, thick, or steel tubing without tool guidance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? This MERWOF 1\/4\" expander head is suited to HVAC technicians, refrigeration repair professionals, and competent DIYers who already own—or plan to acquire—a compatible MERWOF hydraulic tube expander. It’s a practical spare or replacement part for field service trucks, workshop toolkits, and home HVAC maintenance projects where small-bore fittings are common. If you need predictable expansions for 1\/4\" lines, this head provides a compact, serviceable solution when matched with the correct MERWOF expander tool and operating procedure.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this head compatible with non-MERWOF expanders?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Possibly, if the expander uses the same mount type and dimensions.
