The Rothenberger A1 Graduated Expander, shown here, is a six-sizes-in-one tool
with positive fine-adjustment for optimum joint sizes and capillary gaps. The
trapezoid thread has a self-lubricating bronze socket for optimal energy
transmission during expansion. The A1 can expand, reduce and
re-round--heavy-gauge soft copper and soft aluminum tubing.
The special
features of the A1 are typical of Rothenberger's smart design and engineering.
The expander's lightweight yet sturdy construction lets you expand heavy-gauge
tubing with precision and minimal effort. Use the A1 for easy installation of
water pipes, heating pipes, or sprinkler installations.
When you choose Rothenberger
tools, you may spend a little more, but the value is undeniable. Buy your
tube expander once and then cross it off your list as you won't have to
replace it, ever. Though our site has all the specs for every Rothenberger
tool we sell, if you have any additional questions, give our team a call at
