Rothenberger Expander head standard

With the standard expansion heads, installers in the plumbing, heating, and refrigeration/air conditioning sectors can expand copper, stainless steel, and aluminum pipes to create a pipe connection without fittings. They are robust and durable due to specially hardened segments. Up to 50% of the costs for labor time, soldering materials, solder joints, and energy can be saved compared to fitting connections. The socket depth complies with DVGW specifications and guarantees perfect centering as well as a uniform capillary gap. These heads are suitable for expanding copper, stainless steel, and aluminum pipes in sanitary, heating, refrigeration, and air conditioning technology, allowing for the creation of handcrafted sockets with diameters ranging from 8 to 42 mm.
