3Pcs Stainless Steel Hot Air Gun Welding Nozzles
This kit from Lyshujli provides three stainless steel tubular nozzle tips designed for hot air guns. The package targets 32mm-diameter heat gun outlets and claims compatibility with 1500–2000W guns. The material is emphasized for high strength, corrosion resistance and durability under welding temperatures.
Features highlight good plasticity and resistance to deformation, useful when concentrating hot air for plastic sheet welding (PP, PVC). The 20mm wide-mouth option suits broader weld seams, while the set approach supports multiple tip replacements during extended tasks.
SWIGRANCE Hot Air Welding Nozzles 5mm Standard Round Tip
SWIGRANCE offers a single 5mm round tubular nozzle made from 316 stainless steel, engineered for precision heating. The round tip concentrates hot air to a focused point, making it suitable for tight joints or detailed plastic repairs.

Product features note a polished surface for improved corrosion resistance and dimensional stability. The 32mm base diameter is specified to align with many common heat guns. This nozzle is positioned for tasks needing a narrow, controlled airflow rather than broad coverage.
40mm Flat Wide Mouth Tubular Nozzle For Plastic Welding Gun
The Slaige 40mm flat nozzle is a wide-mouth tubular accessory designed to deliver a broader, more even heat pattern. Constructed from 304 stainless steel, it targets applications where larger weld seams or edge heating are needed.
Key details include a base diameter adjustable to 32mm, enabling compatibility with many hot air guns. The flat rectangular shape distributes air over a wider path and is often used with flat welding rods or to soften large plastic surfaces before manipulation.
VOTOER 20mm+40mm Flat Wide Mouth Tubular Welding Nozzle
VOTOER supplies a dual-size replacement set (20mm and 40mm) made from stainless steel with an inner diameter cited as 3.3cm. The product emphasizes ease of replacement and a universal fit for various heat guns, plus design elements to reduce air leakage.

Features note improved alignment between the heat gun outlet and nozzle to prevent hot air gaps. This is relevant for maintaining consistent weld temperature and minimizing localized overheating or inefficient airflow loss during extended operations.
Dura Heat EUH1465 Electric Forced Air Heater With Pivoting Base
The Dura Heat EUH1465 is a compact forced-air electric heater delivering 1500W via a PTC ceramic element. Built with a steel housing, it provides quick warm-up for small spaces and offers both heat and fan-only modes for flexibility.
Its pivoting base enables directional forced air, which can approximate the behavior of a tubular air heater for circulation or spot heating. The model is positioned for workshop or garage use where a rugged, portable heat source is needed rather than precision-welding airflow control.
Buying Guide: How To Choose Tubular Air Heater Nozzles And Units
Selecting the right tubular air nozzle or compact tubular-style heater depends on task type, compatibility and airflow characteristics. Below are key considerations and comparison perspectives to guide purchasing decisions.
Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
1. Application And Heat Profile
- Precision Work: Choose narrow round tips (5mm) to concentrate heat for fine plastic welding or spot repairs.
- Large Seams Or Edge Work: Flat wide-mouth nozzles (20–40mm) distribute heat evenly across wider joints and are better for sheet welding.
- General Heating Or Circulation: Forced-air heaters with pivoting outlets are better for space warming, not precision welding.
2. Material And Temperature Resistance
- 304 vs 316 Stainless Steel: 316 offers better corrosion resistance and slightly improved high-temperature stability; 304 is common and cost-effective.
- Deformation Resistance: Look for nozzles specified as heat-resistant and not prone to cracking or warping at high continuous temperatures.
3. Compatibility And Fit
- Base Diameter: Ensure the nozzle base (commonly 32mm) matches the heat gun outlet for secure fit and minimal air leakage.
- Universal vs Model-Specific: Some nozzles advertise universal fits; check base inner diameter and mounting method to avoid mismatch.
4. Airflow Pattern And Welding Rod Compatibility
- Round Nozzles: Focus airflow for point heating; ideal with round welding rods or precision seams.
- Flat/Speed Tips: Often used with flat welding rods and can include feed openings sized to match rod width for continuous welding.
5. Durability And Replacement Options
- Replaceable Tips: Sets or multi-tip kits allow quick swapping on job sites and reduce downtime.
- Surface Finish: Polished nozzles resist corrosion and soot buildup, preserving airflow characteristics over time.
6. Heater Unit Considerations (If Using Forced-Air Heaters)
- Power Source: Electric PTC heaters provide steady output and safety features; propane/natural gas units deliver high BTU for large spaces.
- Air Direction And Mobility: Pivoting bases and robust housings increase versatility; forced-air units are not substitutes for precision welding nozzles.
7. Safety And Ventilation
- Local Ventilation: Heated plastics can emit fumes; use adequate ventilation and PPE when welding or heating plastics.
- Thermal Protection: Ensure heat guns and heater units have thermal cutoffs, and allow nozzles to cool safely before handling.
8. Performance Trade-Offs
- Focused Heat vs Coverage: Narrow nozzles increase temperature at a point but may require more passes; wide nozzles reduce passes but lower peak temperature.
- Durability vs Cost: Higher-grade stainless (316) and precision-machined tips typically cost more but last longer under heavy use.
9. Maintenance And Replacement Frequency
- Consumable Nature: Nozzles used for continuous high-temperature welding will wear; keep replacement tips on hand for consistent results.
- Cleaning: Periodically remove soot buildup and check for warping to maintain consistent airflow.
10. Matching Nozzle To Job Workflow
- Single-Task Shops: If your tasks are uniform (e.g., large sheet welding), invest in the optimal flat nozzle for that operation.
- Mixed Tasks: Kits or multiple nozzle sizes provide flexibility for both precision and broad application needs.
