Measure the outer diameter of the fitting or barb the hose will slip onto. The hose inner diameter (ID) should match that fitting OD as closely as possible for a secure, leak-free connection. For example, a 6mm (1/4") barb fitting typically pairs with a 6mm ID hose. When in doubt, size down slightly — NBR rubber stretches to grip fittings snugly.

NBR rubber hose of this type is generally rated for low-to-medium pressure applications, typically up to 10–15 bar (145–218 psi) depending on wall thickness and diameter. It is not intended for high-pressure hydraulic circuits. Contact us to confirm the rating for your specific size.

NBR (nitrile butadiene rubber) offers good resistance to petroleum-based fluids and moderate heat, making it suitable for under-hood fuel and oil lines in most automotive applications. For prolonged UV or ozone exposure outdoors, consider adding a protective sleeve or conduit.

This hose is generally compatible with petrol (gasoline), diesel, motor oil, hydraulic oil, and many petroleum-based fluids. It is not recommended for use with brake fluid, strong acids, ketones, or aromatic solvents. Always verify chemical compatibility for your specific application.

Each roll is 5 meters (approximately 16.4 ft). For most DIY automotive fuel line replacements, 5m is sufficient for a single run. Measure your routing path, add 10–15% for bends and connections, then round up. For longer runs, order multiple rolls.

Inner diameter (ID) is the bore size — the measurement of the hollow channel fluid flows through. Outer diameter (OD) is the total width of the hose including the rubber wall. Always match the hose ID to your fitting's barb or nipple OD for a proper seal. The OD determines clearance through grommets or clamps.

Yes. NBR rubber hose cuts cleanly with a sharp utility knife or hose cutter. A straight, square cut ensures the best seal against barb fittings. Avoid sawing motions that can leave ragged edges.
