It is designed for fuel delivery, oil cooling lines, steam emission systems, and similar fluid-transfer uses where resistance to fuels, oils and grease is required. The hose balances flexibility, abrasion resistance and a broad temperature range for on‑vehicle and fixed‑equipment routing.\u003c\/p\u003e\n\n\u003ch3\u003eWhat size and pressure ratings does this EVIL ENERGY hose offer?\u003c\/h3\u003e\n\u003cp\u003eThe hose has a 1\/2\" (12.7 mm) inner diameter with a 0.78\" (20 mm) outer diameter and a 3.7 mm wall thickness. It carries a specified working pressure of 300 psi and a burst pressure of 1200 psi. Minimum bend radius is 4.7\" (120 mm), providing practical routing without kinking when installed to recommended bend limits.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInner diameter: 1\/2\" (12.7 mm)\u003c\/li\u003e\n  \u003cli\u003eOuter diameter: 0.78\" (20 mm)\u003c\/li\u003e\n  \u003cli\u003eWall thickness: 3.7 mm; minimum bend radius: 4.7\" (120 mm)\u003c\/li\u003e\n  \u003cli\u003eWorking pressure: 300 psi; burst: 1200 psi\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich fluids is the SAE 30R7 NBR construction compatible with?\u003c\/h3\u003e\n\u003cp\u003eThe hose's NBR inner tube is formulated to resist petroleum products and common industrial fluids, making it suitable for gasoline, diesel, biodiesel blends, lubricating oils, and many greases.

The braided polyester reinforcement offers tensile strength and resists elongation under pressure cycles, while the outer cover improves abrasion and wear resistance where routing may rub against brackets or chassis. Regular inspection is recommended where the hose contacts sharp edges or high‑heat surfaces.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTemperature range: -40°F to 257°F (-40°C to 125°C)\u003c\/li\u003e\n  \u003cli\u003eBraided polyester reinforcement for strength and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003eOuter cover engineered for oil and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation tips and limitations should installers know?\u003c\/h3\u003e\n\u003cp\u003eUse push‑lock or properly crimped fittings rated for SAE 30R7 fuel hose and avoid tight bending within the minimum radius to prevent kinking. Secure the hose with clamps or supports to minimize vibration and prevent chafing; trim ends cleanly and inspect for any manufacturing debris before assembly. Do not exceed the maximum working pressure or expose the hose to unsupported high temperatures or open flames.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTrim ends squarely; keep connection points clean\u003c\/li\u003e\n  \u003cli\u003eUse compatible push‑lock or crimp fittings and rated clamps\u003c\/li\u003e\n  \u003cli\u003eMaintain bend radius and secure to prevent abrasion and fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Technicians, mechanics, fleet maintainers and DIY builders who need a mid‑size, SAE 30R7 rated fuel line for automotive, marine or light industrial fuel and oil systems.
