Description
Type K Copper Tubing Straightener with Dual-Size Jaws
Product Overview
Instead of carrying separate tools for 3/4" and 1" copper, the Reed RCR341 combines both sizes into one copper pipe straightener rerounder. This Round-It straightener rerounder accepts interchangeable jaws for each size, so a single tool handles rerounding, straightening, and grip work on Type K soft copper. At 18" long and 5.5 lbs, it stays manageable for overhead and trench work.
Key Features
Dual-Size Capacity (3/4" and 1")
The RCR341 holds jaws for both 3/4" and 1" Type K copper tubing, which means one copper pipe straightener rerounder replaces two single-size models.
Five Functions in One Tool
Beyond rerounding, the Reed RCR341 straightens mild kinks, grips coil ends for uncoiling, holds tubing steady during flaring, and guides pipe into alignment for fit-ups.
18-Inch Handles with Adjustable Jaws
The 18-inch handles on this Type K copper tubing straightener give enough leverage to reround without excessive force. The adjustable Lock Screw and Adjusting Screw let you fine-tune jaw pressure for each tube condition.
Pairs with Flaring and Cutting Tools
After rerounding, copper is ready for flaring with a Reed Hammer Flaring Tool or cutting with a standard tubing cutter. This copper rerounding tool fits naturally into prep-to-connection workflows.
How to Use the Reed RCR341
Crews often ask how to straighten copper tubing from a coil and how to reround copper pipe before flaring. The Reed RCR341 handles both tasks.
Rerounding and Straightening
Place the tool over the copper tube and push the handles together, then release. Rotate the tool 90 degrees and repeat. Continue until the tube is round. For Type K tubing pulled from a coil, this copper tubing straightener tool can also remove mild bends along the length.
Adjusting Jaw Pressure
Loosen the Lock Screw, then turn the Adjusting Screw clockwise to close the jaws or counterclockwise to open them. Retighten the Lock Screw once set. Do not overtighten the Lock Screw. Overtightening can cause the handle to break in service.

Frequently Asked Questions
How do you straighten copper tubing from a coil?
Place the Round-It straightener rerounder over the tube and squeeze the handles together. Rotate 90 degrees and squeeze again. Repeat along the length of the copper. This copper tubing straightener tool works best on Type K annealed tubing pulled from coil stock.
Do you need to reround copper before flaring?
Yes. Copper pulled from a coil or handled roughly in the field often goes slightly oval. Flare fittings need a round tube to seal properly. A copper rerounding tool like the Reed RCR341 corrects the shape before you flare.
What is the difference between the Reed RCR341 vs RCR1 vs RCR3/4?
The RCR3/4 handles 3/4" copper only, and the RCR1 handles 1" only. The Reed RCR341 includes jaws for both sizes in one tool, replacing the need to carry two separate straightener rerounders.
What size copper does Reed Round-It straighten?
The Reed RCR341 straightens and rerounds 3/4" and 1" Type K copper tubing. For larger sizes, 1-1/2" and 2", Reed makes the CSR2. Single-size models, RCR3/4 and RCR1, are also available for crews that only work one diameter.
How do you reround copper pipe before flaring?
Position the copper pipe straightener rerounder over the tube, squeeze the handles, and release. Rotate 90 degrees and repeat until the tube is round. Adjust jaw pressure with the Lock Screw and Adjusting Screw as needed.
