If you’ve ever struggled with a leaky pipe or needed to solder copper fittings in tight spaces, you know how frustrating it can be without the right tool. That’s where the Bernzomatic 5 Piece PK1001 Brass Pencil Flame Plumbing Torch Kit comes in—designed for precision, reliability, and ease of use. Whether you’re a weekend DIYer or a seasoned plumber, this compact torch kit delivers professional-grade performance without the complexity.
What Is the Bernzomatic PK1001 Torch Kit?
The Bernzomatic 5 Piece PK1001 Brass Pencil Flame Plumbing Torch Kit is a compact, versatile torch system designed for precision soldering, brazing, and heating tasks—especially in plumbing applications. Its signature “pencil flame” offers a focused, high-temperature flame ideal for tight joints and delicate work.
Unlike bulky torches that struggle in confined areas, this kit includes a brass torch head that attaches to standard Bernzomatic fuel cylinders (like the popular MAP-Pro or propane canisters), giving users both portability and control.
According to Bernzomatic’s engineering team, the pencil flame can reach temperatures up to 2,500°F (1,371°C) when used with MAP-Pro gas—hot enough to melt solder quickly and cleanly without overheating surrounding materials.
Who Should Use This Torch Kit?
This kit is perfect for:
- Homeowners tackling minor plumbing repairs (e.g., fixing a dripping faucet or replacing a valve).
- HVAC technicians needing precise flame control for brazing copper refrigerant lines.
- Jewelers or hobbyists who require a fine, steady flame for small-scale metalwork.
- Plumbers working in cramped crawl spaces or behind walls where bulky torches won’t fit.
A 2023 survey by HomeAdvisor found that 68% of DIY plumbing projects involved soldering copper pipes—and nearly half of respondents cited “lack of proper tools” as their biggest frustration. The PK1001 directly addresses that gap.
What’s Included in the 5-Piece Kit?
The Bernzomatic PK1001 isn’t just a torch—it’s a complete system. Here’s what you get:
- Brass Pencil Flame Torch Head – Precision-engineered for a clean, concentrated flame.
- Trigger-Start Ignition Torch Handle – Ergonomic design with built-in spark ignition (no lighter needed).
- Two Fuel Cylinders – Typically includes one MAP-Pro and one propane canister (varies by retailer).
- Solder Wire – Lead-free, rosin-core solder suitable for potable water lines.
- Flux Brush & Flux Jar – For cleaning and preparing pipe joints before soldering.
💡 Pro Tip: Always use lead-free solder (as included) for any plumbing that carries drinking water. The EPA and NSF International strictly regulate this—see more on [lead in plumbing](https://en.wikipedia.
How Does It Compare to Other Plumbing Torches?
Let’s break down how the PK1001 stacks up against common alternatives:
| Feature | Bernzomatic PK1001 | Generic Propane Torch | Professional Oxy-Acetylene Kit |
|---|---|---|---|
| Flame Temp (with MAP-Pro) | ~2,500°F | ~1,990°F | ~3,500°F |
| Portability | Excellent (handheld) | Good | Poor (tanks & hoses) |
| Ease of Use | Beginner-friendly | Moderate | Requires training |
| Best For | Soldering, small brazing | General heating | Heavy-duty welding |
| Price Range | $35–$50 | $20–$30 | $200+ |
Key Takeaway: The PK1001 strikes the ideal balance between performance, safety, and affordability—especially for jobs under 1″ pipe diameter.
Step-by-Step: How to Solder a Copper Pipe with the PK1001
Follow these steps for a leak-free joint every time:
- Cut & Clean the Pipe
Use a tubing cutter to make a clean, square cut. Deburr the inside edge and wipe the pipe and fitting with a clean cloth. - Apply Flux
Use the included brush to apply plumber’s flux to both the pipe end and inside the fitting. This prevents oxidation and helps solder flow evenly. - Assemble the Joint
Insert the pipe fully into the fitting. Wipe away excess flux. - Heat Evenly
Attach the brass pencil flame head to your MAP-Pro cylinder. Ignite with the trigger. Hold the flame 1–2 inches away, rotating the joint for 10–15 seconds until the flux bubbles. - Apply Solder
Touch the solder wire to the opposite side of the joint from the flame. Capillary action will draw it in. Use ~1 inch of solder per inch of pipe diameter. - Cool & Test
Let the joint cool naturally (don’t quench with water). Once cool, turn on the water and check for leaks.
⚠️ Safety First: Always work in a well-ventilated area, wear safety glasses, and keep a fire extinguisher nearby. Never leave a lit torch unattended.

Real-World Performance: What Users Say
On Amazon (as of late 2024), the Bernzomatic PK1001 holds a 4.7-star average from over 8,200 reviews. One verified buyer, a licensed plumber from Ohio, wrote:
“I keep this in my truck for quick service calls. It lights every time, even in winter, and the pencil flame lets me solder behind a sink without removing the cabinet. Worth every penny.”

“Fixed my hot water heater inlet in 20 minutes. Never soldered before—this kit made it easy.”
These testimonials align with Bernzomatic’s reputation: over 130 years in the heating and soldering industry.
FAQ Section
Q: Can I use this torch for silver soldering or brazing?
A: Yes—but only with MAP-Pro fuel, not standard propane. MAP-Pro reaches ~2,500°F, which is sufficient for silver solder (melts ~1,300–1,500°F) and some low-temp brazing alloys. For high-temp brazing (>1,600°F), consider a more powerful system.
Q: Is the brass torch head replaceable?
A: Absolutely. Bernzomatic sells the BT1001 brass torch head separately. It screws onto any compatible Bernzomatic handle.
Q: How long does a fuel canister last?
A: A standard 14.1 oz MAP-Pro canister provides about 45–60 minutes of continuous flame. For occasional DIY use, one canister can last months.
Q: Can I use this kit on PVC or plastic pipes?
A: No. The flame will melt or ignite plastic. This kit is only for metal pipes—copper, brass, or steel.
Q: Is it safe for indoor use?
A: Only with excellent ventilation. Never use in small, enclosed spaces. Always follow local fire codes and manufacturer safety guidelines.
Q: Does it work in cold weather?
A: Yes, but performance drops below 40°F (4°C). Warm the fuel canister in your pocket for 5–10 minutes before use for best results.
Conclusion
The Bernzomatic 5 Piece PK1001 Brass Pencil Flame Plumbing Torch Kit is more than just a tool—it’s a confidence booster for anyone tackling plumbing repairs. With its precision flame, all-in-one design, and professional-grade results, it eliminates guesswork and delivers reliable, leak-free joints.
