YSIL 1" (25mm) Fuel Line Hose — 6.6ft NBR Rubber, 300 PSI Working Pressure, Oil-Resistant

YSIL 1" (25mm) ID fuel line hose is a 6.6-foot NBR rubber push-lock hose built for fuel, oil and ventilation lines that needs high-temperature, oil-resistant flexibility and up to 300 PSI working pressure.

This heavy-duty fuel hose combines a nitrile-butadiene (NBR) rubber inner compound with braided fiber reinforcement to deliver a balance of chemical resistance, bendability and long service life. Sized at a 1" (25mm) inner diameter and 1.35" (34.4mm) outer diameter, the 6.6-foot length suits engine bays, routing across chassis and replacement runs for cars, trucks, buses and industrial equipment. Specs include a typical working pressure around 217 PSI, a maximum rated working pressure of 300 PSI and a burst rating near 1200 PSI, with a temperature window that spans -40°F to 257°F (-40°C to 125°C).

What types of fluids and systems can this hose handle?

This NBR rubber fuel line is formulated for direct contact with gasoline, diesel, oil and many petroleum-based fluids, plus use in ventilating and PCV lines. It is commonly installed in fuel supply, oil coolers, steam or emission recovery, brake return lines and transmission or clutch return circuits where compatible.

• Compatible with gasoline, diesel and most engine oils
• Suitable for PCV, vapor recovery and oil cooling lines
• Avoids aggressive chemicals not recommended for NBR (check fluid compatibility)

How does the hose perform under pressure and temperature extremes?

The braided fiber reinforcement and NBR compound provide reliable performance across wide operating conditions. Normal working pressure is rated around 217 PSI, with a conservative maximum working rating of 300 PSI and a substantial burst margin for safety. Temperature tolerance from -40°F to 257°F enables use in cold climates and hot engine compartments without significant loss of flexibility.

• Working pressure: ~217 PSI; max working: 300 PSI
• Burst pressure approximately 1200 PSI for safety margin
• Temperature range: -40°F to 257°F (-40°C to 125°C)

How easy is it to install, route and cut to fit?

The hose’s pliable construction and small minimum bend radius simplify routing through tight engine bays and chassis passages. It can be trimmed to length with a utility knife or hose cutters, and its push-lock friendly diameter fits common clamps and fittings used in automotive and industrial applications. The flexibility also minimizes kinking when navigating bends.

• Minimum bend radius: 4.7 inches (120 mm)
• Can be cut to desired length for custom installations
• Works with standard clamps, push-lock fittings and hose ends

Who is this for? Technicians, mechanics and DIYers replacing or upgrading fuel and oil lines on cars, trucks, buses, ATVs and light industrial machines will find this YSIL hose useful when they need a robust, oil-resistant rubber line in a 1" diameter. It’s aimed at projects that require a longer run (6.6 ft), the ability to bend through tight spaces, and a hose that tolerates common engine temperatures and pressures. Before installation, verify fluid compatibility and local regulations for fuel-line materials and fittings; use proper clamps and routing to prevent chafing, heat exposure and sharp bends.
