5-Blade Sheet Metal Crimper

Equip yourself with only the best during HVAC installation with the C5R Malco 5 Blade Sheet Metal Crimper. The C5R creates long, shallow double crimps that replicates factory indentations. These longer shallower crimps result in a tighter fitting, more self supporting, leak proof connection. Made with nickel plating to help resist corrosion and hardened steel for greater strength and resistance to abuse.

The Malco 5 Blade Sheet Metal Crimper also features comfortable ergonomic RedLine Handle’s. These handles offer non-slip handle grip contours, spring handle actuation, and a thumb operated handle latch. The engineered handle opening of the tool compliments the natural power stroke of any user’s hand.


•    Quickly downsize ends of round duct and stove pipe.
•    Creates a tight fitting, more self-supporting crimp connection.
•    Compound leverage produces 7 to 1 mechanical advantage.
•    The 5 Blade Crimper also features Malco’s ergonomic RedLine Handles that won’t wear you down during continual use.

Malco Crimper

I just wanted to compliment you on your 5-Blade Sheet Metal Crimper hand tool C5R. I'm a handyman and work with ductwork every once in awhile and always used needle nosed plyers for the male ends. But on a recent job, I decided to buy your tool, and oh my god what a difference. The tool is incredibly easy to use and produced perfect results! No more struggling to make things nice, for me. Thank you.

It works well, gives a professional quality result

Unless you're a contractor doing a lot of vent work, you won't use this much. But when you need it, you need it. This is very easy to use and gives a very nice, professional looking crimp.

Pipe crimper

It met expectations. It fulfills a need I had for which I had no other solutions. It was easy to use.


Improved over old model

Like the lock location, (better than older version) We use this EVERY DAY. Looks well constructed. Would buy it again.

Great working Crimper!

I bought this tool because I needed to fit the same size pipe into another of similar size. I tried & I tried & couldn't get them to connect. I saw this tool while my heating duct work was being worked on & decided this was a tool to have! I bought it & used it on one end of the 3" pipe & walla! It fit fine!Very well made & is well worth the price.
