Gas grills are convenient but lack authentic smoke flavor. A smoke tube solves this problem for under $20, transforming your grill into a smoke-producing machine. This guide covers everything you need to know about using a smoke tube effectively.

Quick Roundup List

Understanding Smoke Tubes: What They Are and How They Work

A smoke tube is a perforated metal cylinder holding wood pellets or chips to produce continuous smoke. Most use 304 stainless steel for durability and food safety. Perforations allow oxygen flow, creating controlled smoldering that generates hours of smoke without flames.

Hexagonal tubes prevent rolling, while oval designs save space. Some feature diamond-shaped air inlets for better airflow. Once lit and placed horizontally, a smoke tube produces smoke for 2 to 8 hours depending on size.

When you light pellets at one end, they burn slowly side to side. Perforations ensure steady oxygen supply. This produces clean, flavorful smoke.

Smoke tubes work on any grill type—gas, electric, charcoal, or pellet. They’re especially valuable for gas grill owners wanting smoke flavor without a dedicated smoker.

Step-by-Step: Lighting Your Smoke Tube

Proper lighting ensures your smoke tube produces smoke for the full duration.

Step 1: Choose Your Wood
Select hardwood pellets like hickory, oak, apple, or cherry. These woods impart distinct flavors—hickory for bold taste, apple for mild sweetness. Avoid softwoods like pine or cedar, which create acrid smoke and potentially harmful compounds.

Step 2: Check for Moisture
Ensure the tube and pellets are completely dry. Damp pellets won’t light properly. Store pellets in airtight containers to prevent moisture absorption.

Step 3: Fill and Pack
Fill your smoke tube about 90% full, leaving a slight space at the top. Tap it on a hard surface to settle pellets and eliminate air pockets. Tighter packing means longer burn time.

Step 4: Light It
Stand the tube upright with the filled end at the top. Use a propane torch or large butane lighter to ignite pellets. Standard lighters often lack sufficient flame.

Step 5: Let It Burn
Allow flames to burn for 8-10 minutes. You’ll see pellets glowing orange. This extended burn ensures the ember establishes deep enough to continue after you blow out the flame.

Step 6: Extinguish and Verify
Blow out visible flames. You should see glowing embers and smoke rising. If smoke production seems weak, relight for another 2-3 minutes.

Step 7: Place Horizontally
Lay the smoke tube flat on your grates. Smoke will flow through perforations for several hours.

Placement Strategy for Maximum Smoke

Placement affects smoke distribution and burn consistency. For gas grills, place the smoke tube away from direct burner flames, ideally near air vents. On pellet grills, position it to supplement existing smoke systems.

Keep the tube 12-18 inches from food. This allows smoke to disperse evenly rather than concentrating in one spot.

Horizontal placement is critical after lighting for even burn progression.

Hot Smoking vs. Cold Smoking Techniques

Smoke tubes excel at both methods with slight technique differences.

Hot smoking uses temperatures between 225-275°F with your grill actively heating. The smoke tube adds supplemental smoke while food cooks. This works for brisket, ribs, pork shoulder, and chicken. Fill your tube, light it, place it on the grill, and start cooking. Most hot smoking uses 2-4 hours of smoke, so a 12-inch smoke tube lasts without refilling.

Cold smoking keeps temperatures below 90°F with the grill turned off. Only the smoke tube burns, infusing flavor without cooking food. This technique is ideal for cheese, salmon, bacon, and nuts. Light the tube, place it in your grill, close the lid, and let smoke circulate. Monitor temperature—on hot days, you may need ice packs to stay below 90°F. Cold smoking often runs 4-8 hours, so plan for potentially refilling a standard tube.

Troubleshooting Common Issues

Tube Goes Out Prematurely
Insufficient initial lighting is the most common problem. If your smoke tube extinguishes within an hour, you didn’t burn it long enough. Extend the vertical burn to 12-15 minutes. Check pellet moisture—even slightly damp pellets cause extinction. Ensure adequate airflow by positioning near vents.

Insufficient Smoke
Weak smoke indicates too much airflow cooling the ember, or pellets packed too loosely. Adjust vents to reduce excessive draft. When filling, tap the tube firmly to compact pellets. Dense packing slows burn rate and intensifies smoke output.

Uneven Burning
If pellets burn unevenly, pellet quality may be the issue. Low-quality pellets contain fillers or inconsistent moisture. Switch to premium hardwood pellets. Store pellets in airtight containers.

Safety, Cleaning, and Maintenance

Always use heat-resistant gloves when handling the tube during or after use. The metal gets extremely hot. Never use flammable liquids to light the tube.

After each use, let the tube cool completely (45-60 minutes). Tap out remaining ash. Use a grill brush to clean the interior, removing residue.

For deep cleaning, rinse with warm water and mild dish soap. Avoid abrasive scrubbers. Dry thoroughly before storing—moisture promotes rust. Store in a dry location.

Choosing the Right Smoke Tube: Buying Guide

Key features to consider:

Size determines duration. A 12-inch tube provides 4-8 hours, perfect for long cooks. A 6-inch tube provides 2-3 hours for quicker sessions.

Material should be 304 stainless steel—food-grade, rust-resistant, and heat-tolerant.

Design affects stability. Hexagonal and oval shapes prevent rolling. Round tubes work but require careful placement.
