With the ribbed expander heads, installers in the refrigeration and air conditioning sector, as well as in industry, can expand pipes made of copper, stainless steel, and aluminum to create a pipe connection without fittings. They are robust and durable due to specially hardened segments. There are savings of up to 50% in labor costs, soldering materials, solder joints, and energy compared to fitting connections. The socket depth complies with DVGW specifications, and the forced guidance ensures perfect centering and an even capillary gap. Ideal for creating precise hose connections in vibration-prone units in climate technology, vehicle construction, and industrial connection technology. The ribbed expander head is suitable for manually expanding pipes made of copper and stainless steel in the dimension of 28 x 1.5 mm.
