Amazon does NOT have the best pricing on these pliers, and they also don’t carry the full line of these pliers. You’ll want to check KC Tool, ChadsToolBox, or your other favorite Knipex dealers for price comparison.

If you’re looking for something a little different (and less expensive) for use on PVC pipes and fittings, consider the Knipex 81 03 230, which has 25 to 65 mm capacity.These pliers have a different slip joint-style adjustment mechanism.
These PVC pliers are around $50 on Amazon. A plastic-lined-jaws version of these PVC pliers are also available. Although it doesn’t look like it, these pliers are said to have serrated jaws.
These look pretty handy, but steeply priced. But if you need a unitasker that’s best for working on fittings, tubing, pipes, and similar materials, these look like they’ll do the trick.
