Ruikarhop 3/8" ID Fuel Hose 25ft NBR Rubber SAE 30R7 — 300 PSI Working Pressure, Includes 10 Clamps

Ruikarhop 3/8" ID Fuel Hose is a 25-foot NBR rubber push-lock fuel line rated SAE 30R7 that handles up to 300 PSI working pressure and comes with 10 clamps.

This heavy-duty fuel hose is built for small engines, outdoor power equipment, and workshop projects that require a flexible, chemical-resistant line. Made from nitrile butadiene rubber (NBR) and engineered to meet SAE 30R7 characteristics, the hose resists gasoline, biodiesel blends, lubricants, hydraulic fluids, and coolants while operating across a wide temperature span.

How tough is this hose for fuel and oil exposure?

The Ruikarhop NBR compound is formulated to stand up to common fuels and many oil-based fluids without rapid deterioration. It’s compatible with unleaded gasoline, biodiesel (including some blends), ethanol mixtures up to E-85, and a variety of lubricants and hydraulic oils.

• Material: NBR (nitrile butadiene rubber) for fuel and oil resistance
• Compatible with biodiesel, gasoline, E-10, E-85, lubricating and hydraulic oils
• SAE 30R7 construction for typical fuel-line performance

What sizes, pressure ratings, and temperature limits should I expect?

The hose is sized with a 3/8" (10 mm) inner diameter and approximately 2/3" (16 mm) outer diameter, supplied as a 25-foot length to cover multiple routing needs. It carries a working pressure of 300 PSI and a burst pressure around 1,160 PSI, making it suitable for many small-engine and low-to-moderate pressure systems.

• Inner diameter: 3/8" (10 mm); outer diameter: ~2/3" (16 mm)
• Length: 25 feet—cut-to-length convenience for projects
• Working pressure: 300 PSI; burst pressure: ~1,160 PSI
• Operating temperature range: -40°F to 257°F

Is it ready to install and what accessories are included?

The kit arrives as a 25-foot push-lock compatible hose and includes 10 hose clamps to secure fittings at both ends and intermediate points. The hose’s push-lock fit and flexible construction simplify routing around engine bays, tanks, and pumps without specialized tools.

• Includes ten metal clamps for secure connections
• Push-lock friendly for common barb fittings and quick installs
• Flexible for tight bends and compact routing in small engines

How durable is the hose over time and in different conditions?

NBR rubber offers good resistance to abrasion, oil swelling, and fuel-induced hardening relative to general-purpose hoses, giving reliable service life in workshop and outdoor settings when used appropriately. Keep in mind that extreme chemical exposure or pressures beyond ratings will shorten lifespan—inspect regularly and replace if cracking or softening appears.

• Designed for abrasion and chemical exposure typical of fuel systems
• Wide temperature tolerance from -40°F to 257°F for seasonal use
• Manufacturer offers a 3-month warranty and customer support

Who is this for? The Ruikarhop 3/8" ID 25-foot NBR fuel hose is ideal for DIY mechanics, lawn and garden equipment owners, small-engine repair shops, and hobbyists who need a resilient, long-length fuel line for gasoline, biodiesel blends, or oil-related routing. Choose this hose when you want a ready-to-cut length with clamps included and a pressure rating suitable for many low-to-moderate pressure fuel system tasks. Always confirm compatibility with your specific fluid, fitting type, and system pressure before installation, and replace the hose if signs of wear appear.
