NOWBALL 2in Automotive Air Duct Hose
This NOWBALL duct is built for high-temperature and demanding environments. It uses a double-layer flame retardant silicone outer with double-layer fiberglass fabric and internal spring steel wire for shape retention. The product lists a wide temperature range of -95°F to 575°F, making it suitable for hot-air routing near exhausts, heaters, and diesel heaters.
Key practical points from the features: the hose is flexible yet reinforced to resist kinks, has a smooth interior for reduced airflow resistance, and is designed for repeated high-heat use. The listing specifically warns about fiberglass contact and includes gloves in the package.
Use cases: recommended where high heat resistance is required (engine bays, dryer/heater ducts). Note the need to follow safety guidance when handling fiberglass-reinforced products.

The SOVARCATE ducting is a 2-inch diameter, 1 meter (3.3 ft) length silicone hose with multi-layer construction. The features highlight a temperature range of -95°F to 575°F, a kink-free steel wire reinforcement, and a smooth interior to reduce airflow drag.
This product emphasizes 4-layer protection and an adhesive coating to bond layers for enhanced durability. The steel wire reinforcement supports flexibility in tight routing without collapsing, which is useful for intake and cooling ducting in confined spaces.
Use cases: suitable for applications requiring heat resistance and kink-free performance, such as intake systems, coolant ventilation, and exhaust-adjacent ducting. Safety tip: contains fiberglass—use gloves and a mask when handling.
Dorman 96002 HVAC Vent Hose – 2 Inch
The Dorman 96002 is a universal-fit 2-inch diameter vent hose made of high-strength nitrile rubber. Key features include resistance to cracking, the ability to be cut to length, and an expandable design for adjustable fit.
Prospective users will note the hose is intended for broad automotive, household, and workshop uses where a rubber hose is preferred over metallic or silicone alternatives. The flexibility and cut-to-fit capability make it useful for retrofit and repair tasks.

Use cases: ideal for applications requiring resilient rubber material, moderate heat resistance, and customization by trimming. Suitable for HVAC vent routing, cabin air outlets, and general-purpose ducting inside vehicles or small workshops.
Vintage Air 2 in Diameter Plastic Hose, 10 ft
The Vintage Air hose is a 2-inch diameter plastic duct supplied in a 10-foot length. The listing identifies it as an auto part with standard package dimensions and a single-piece quantity.
This product is aimed at installations where a longer run is needed and where plastic ducting provides sufficient heat tolerance. Plastic hoses are typically lightweight, easy to route, and cost-effective for air distribution where temperatures remain within plastic’s material limits.
Use cases: recommended for longer low-to-moderate temperature runs such as cabin air distribution, defrost outlets, and general HVAC venting where extreme heat exposure is unlikely.
2 Inch ID Duct Hose AC Heater Defrost, 6 Feet
This 6-foot plastic duct from Old Air Products highlights very flexible construction and long-lasting durability. It’s designed for ease of installation in HVAC and automotive defrost or AC applications.
Features suggest the product is straightforward to work with when routing through tight spaces or around obstacles. The 6-foot length covers many common runs and can be trimmed if needed.
Use cases: suited for AC, heater, and defrost outlets where flexibility and moderate temperature tolerance are required. It provides a practical option when you need an easy-to-install plastic duct for interior airflow routing.
Other Relevant Replacement Hoses From Dorman
Dorman 96034 is a 2″ x 28″ paper/aluminum compatible carburetor pre-heater hose designed as a direct replacement to restore original fit and function after heat or vibration failure. Construction focuses on matching OEM performance with durable materials.
Dorman 96024 is a 2″ x 18″ aluminum compatible pre-heater hose that emphasizes direct replacement properties and material durability for applications near heat sources where OEM fit is important.
Buying Guide: How To Choose The Right 2 Inch Heater Duct Hose
When selecting a 2 inch heater duct hose, consider the following key factors to ensure the hose matches your application and environment.
Temperature Resistance
Determine the maximum temperatures the hose will encounter. For high-heat areas (near exhaust manifolds, diesel heaters, or heat exchangers), choose hoses rated for elevated temperatures, such as silicone or multi-layer fiberglass reinforced types that list specific temperature ranges.
Material And Durability
- Silicone/Fiberglass — High heat resistance, flexible, often reinforced with steel wire. Ideal for hot zones.
- Rubber (Nitrile) — Resistant to cracking, flexible, easy to trim; suitable for moderate heat and vibration-prone locations.
- Plastic — Lightweight, economical, long runs possible. Best for low-to-moderate temperatures.
- Aluminum/Paper-Compatible — Intended for OEM-style replacements where original material compatibility matters.
Flexibility And Kink Resistance
Consider whether the hose needs to bend around tight corners. Steel wire reinforcements and multi-layer designs typically offer kink-free performance, while simple plastic or rubber hoses may collapse under sharp bends.
Length And Trimability
Measure the run and choose a hose with sufficient length. Many hoses can be cut to length, which helps with custom installations. Consider whether a single long length is preferable to multiple couplings.
Interior Surface And Airflow
A smooth interior reduces airflow resistance and improves efficiency. If maintaining airflow or minimizing pressure loss matters, favor hoses that advertise a smooth inner surface or low-friction interior.
Attachment Method
Plan how the hose will be secured: hose clamps, collars, or OEM connectors. Reinforced hoses may require specific clamps or sleeves to prevent damage. Ensure the chosen hose diameter and thickness fit existing outlets.
Chemical And Environmental Resistance
Check resistance to oils, fuels, UV, and chemicals if the hose is exposed to these elements. Silicone and certain rubbers handle chemical exposure better than basic plastics.
Safety And Handling
Some high-performance hoses contain fiberglass or other fibers. Follow handling guidance—wear gloves and a mask if required—and ensure proper sealing to prevent fiber release into airflow paths.
Application-Specific Recommendations
- For high-heat engine bay routing: choose reinforced silicone/fiberglass hoses with high temperature ratings.
- For general HVAC or cabin vent runs: plastic or rubber hoses with adequate length and flexibility are often sufficient.
- For OEM-style repairs: pick Dorman or similar direct replacement hoses listed as compatible with your vehicle model.
Comparison Perspectives
Compare hoses across these perspectives: material vs. temperature capability, flexibility vs. kink resistance, cost vs. lifespan, and runtime length vs. number of joints. Prioritize the characteristic most critical to safety and performance for your project.
Using the guidance above will help you match a 2 inch heater duct hose to your vehicle or HVAC needs by balancing heat tolerance, flexibility, durability, and installation simplicity.
