Previous PagePrevious PageNext PageNext page       


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.

Rothenberger hand tools give tradesmen of all types the confidence that comes with having the best materials and design at their tool boxes. Like all Rothenberger tools, the hand tools have the Quality Assurance Certification ISO 9000 / 9001 / 9002, which covers everything from the raw materials to the service you receive after a sale. At CMS Industrial Equipment Company, we stand behind all of the Rothenberger tools we sell, including their exceptionally made tee extractors.

The extractor bells are nickel-plated and sit with a double vee block for accurate positioning. This gives you precise 90-degree branches every time. You just drill the pilot hole, introduce the extractor hook to the drilled hole and firmly screw the bell to the wall of the tube. Next, hold the extractor in place while you extract, particularly while make your last final few turns.
