Here is our shortlist for the best stove pipe crimper. Stove pipe season comes with the first cold snap: the pipe goes up, the joints need crimping, and a pair of pliers will not make a clean male end. A crimper folds the edge of the pipe so each section slips into the next, which is what keeps a stove pipe run tight and drafting right. This guide compares five 5-blade crimpers by the things that decide the joint: the gauge range they handle, the blade steel, the handle design and what each listing states about warranty.

How we scored them
Each crimper is scored out of 10 on performance, build, value, safety and warranty, using only what the listing publishes. Performance covers gauge range and throat depth; build covers blade steel and handle construction.
| Product | Woodlot Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Klein 86520 Crimper | 9.7 | 30 | 22 | 20 | n/a | 2 |
| HURRICANE Crimper | 9.6 | 30 | 21 | 21 | n/a | 0 |
| SLNIHAMS Crimper | 9.6 | 29 | 21 | 20 | n/a | 0 |
| PLATATO Sheet Crimper | 9.6 | 28 | 21 | 20 | n/a | 0 |
| GINXFIT Hand Crimper | 9.5 | 27 | 20 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
The Klein 86520 leads on its stated warranty and brand support. The HURRICANE follows on marked throat depth, and the GINXFIT on its stated replacement term. The SLNIHAMS and PLATATO round out the list on handling features.
Buying guide: choosing the best stove pipe crimper
Gauge range: 22 or 24 to 28
Three picks list a 22-28 gauge range; the Klein lists 24 gauge steel and 28 gauge stainless, and the GINXFIT bullets list 24 gauge steel and 28 gauge stainless. Check the gauge of your pipe against the listing before you buy: a crimper rated for thinner sheet may not close heavier pipe cleanly.
Blade steel and throat depth
Blades run from forged alloy steel to heat-treated carbon steel to 50# steel plate, all in a 5-blade layout. Throat depth is stated on two picks: 1-1/4 in on the HURRICANE with 1/4 in markings, and up to 0.16 in on the GINXFIT. The HURRICANE’s markings keep each crimp the same length around the pipe, which matters when a joint has to look straight.
Handles, locks and lanyard holes
Three picks list a safety or security lock that keeps the tool closed in the toolbox. The SLNIHAMS and PLATATO list lanyard holes, which the listings tie to working at height. Grips run from TPR to contoured steel to textured Tyregrip with finger guards. If the pipe run is overhead, pick a tool with a lanyard hole and a lock.
Warranty in writing
Only the Klein states a full warranty term, 1 Year Manufacturer. The GINXFIT states six months of free replacement, which earns partial credit. The other three state no warranty term, so the purchase rests on the listing alone.
Around the Woodpile
- Clip a lanyard through the SLNIHAMS or PLATATO hole when crimping pipe above the stove.
- The HURRICANE’s 1/4 in depth markings keep every crimp the same length around the pipe.
- Engage the safety lock for storage; the SLNIHAMS, PLATATO and HURRICANE list one.
- The Klein’s contoured grips cover hardened steel handles, per the listing.
Wear eye protection and gloves for cutting, splitting and handling, follow every tool's manual, install stoves to code, and have the chimney inspected and cleaned every year. See EPA Burn Wise and NFPA heating safety. Read our Safety Disclaimer.
Frequently Asked Questions
What does a stove pipe crimper do?
It folds a series of crimps around the end of a pipe section to make a male end that slips into the next section. All five picks here are 5-blade hand crimpers built for that job on stove pipe, duct and downspout.
What gauge stove pipe can these crimpers handle?
Three list 22-28 gauge; the Klein lists 24 gauge steel and 28 gauge stainless; the GINXFIT bullets list 24 gauge steel and 28 gauge stainless. Match your pipe to the listing before you buy.
Do I need a lanyard hole?
The SLNIHAMS and PLATATO list lanyard holes, which the listings tie to working at height. The other three do not state one, so tie off another way if the work is overhead.
Which crimpers state a warranty?
The Klein states a 1 Year Manufacturer warranty and the GINXFIT states six months of free replacement. The SLNIHAMS, PLATATO and HURRICANE listings state no warranty term.
Can I use a crimper on stainless stove pipe?
The Klein lists 28 gauge stainless, the SLNIHAMS lists 22-28 gauge galvanized or stainless, and the HURRICANE lists stainless among its 22-28 gauge range. Check the gauge first, since stainless work-hardens fast.
