The following sections profile each option with its primary features, helping you compare form, function, and installation considerations for your specific setup.
A.A Black Plastic Flex Battery Vent Hose Tubing 1-3/4″ ID
Materials and construction emphasize UV resistance and heavy-duty use. The 1-3/4″ ID is suitable for battery boxes and vent systems in RVs and trailers, providing a good balance of flexibility and durability under exposure to outdoor elements. The hose is designed to resist cracking and environmental wear, supporting long-term performance in challenging installations.
QuQuyi 1-3/4″ ID x 2-1/8″ OD Heavy-Duty Tubing
This PVC tubing uses clear-transparent vinyl for visibility inside the line. With an ID of 1-3/4″ and an OD of 2-1/8″, it supports moderate pressures and temperatures from -4°C to 66°C (-40°F to 150°F). Features include a firm 73a rating, making it robust for oil, fuel, water, and air piping, and a maximum working pressure around 60 psi with a burst rating of 120 psi.
TKKEUEP Gasoline Fuel Filler Neck Hose
The reinforced fuel filler hose features nylon cording for added strength and a nitrile tube rated for temperatures from -40°F to 212°F. It is designed to accommodate long runs up to the filler neck and is compatible with EPA concentration limits. Length and inside diameter align with typical fuel systems in many vehicles and trailers, providing installation flexibility.
Ticon 1.75″ ID Silicone Coupler
Black 4-ply reinforced high-temp silicone coupler with a 1.75″ ID and 3″ length. This part supports strong tube engagement and enhanced clamping area, suitable for high-temperature or heat-exposed connections in automotive or industrial settings where silicone performance matters.
Gates 26611 GAT: Green Stripe Heavy-Duty Vulco-Flex Hose
Although listed with a different product line, this hose remains notable for its electrochemical degradation resistance and built-in steel spiral supporting medium curves without kinking. Its EPDM tube and Neoprene cover extend service life in cooling applications and beyond, making it a solid option for 1 3/4″ ID cooling or similar pathways in engines and equipment.
BEIJIULI 1 3/4″ ID Radiator Coolant Air Hose
Silicone-based radiator coolant air hose with four-layer reinforcement offers flexibility, temperature resistance, and compatibility with coolant, glycol, water, steam, and air systems. The 12-inch length supports straightforward trimming to fit various radiator or turbo piping configurations, with easy-cut features for custom installations.
QuQuyi 1-3/4″ ID x 2-1/8″ OD Heavy-Duty Tubing (1.3 ft)
This variant mirrors the larger tubing option with the same ID and OD specifications, but shortened to 1.3 feet. It maintains a 60 psi max working pressure and 120 psi bursting pressure, making it suitable for compact runs or shorter extension lines in automotive or marine environments.
1 3/4 Inch Fuel Filler Neck Hose With Clamps
This reinforced fuel hose, with a 1.75″ ID and 15 7/8″ length, includes four clamps for secure installation. Constructed from premium nitrile rubber with nylon cording, it promises oil resistance and robust durability in automotive fuel systems. The product is designed for easy cutting to fit precise needs and supports straightforward installation.
Buying Guide
Key purchase considerations for 1 3/4″ ID hoses include:
- Material compatibility: Choose PVC, nitrile, or silicone based on the conveyed substance (fuel, coolant, air, or water) and chemical exposure.
- Temperature and pressure: Ensure the hose supports the operating temperature and pressure ranges of the system; check burst and working pressure ratings when applicable.
- Flexibility and length: Longer hoses may require careful routing; silicone variants often offer greater flexibility at higher temperatures.
- Reinforcement: Nylon cords or steel reinforcements add strength for high-vacuum or high-pressure lines and resist collapsing under bending.
- Clamps and fittings: Some kits include clamps; verify compatibility with your hose ID and clamp style to ensure a proper seal.
- Durability and UV exposure: Outdoor or uncovered installations benefit from UV-resistant materials to prevent cracking and degradation.
- Intended use: Distinguish between fuel, coolant, air, and general purpose lines to avoid cross-application issues and ensure safety compliance.
When comparing options, consider the most common systems in American vehicles and RVs: battery venting, fuel fillers, radiator and coolant pathways, and general purpose suction or transfer lines. Durability, chemical resistance, and temperature tolerance are often deciding factors, with silicone couplers favored for high-temperature connections and reinforced hoses preferred for long runs or high-stress routes.
