With a 3\/4-inch inner diameter, an outer diameter of 1.10 inches, and a full 5-foot length, it offers a straightforward path for radiator connections and hot water heater lines. The black EPDM rubber combines flexibility with long-term durability to handle daily heat exposure, fluid variety, and routing challenges.\u003c\/p\u003e\n\u003ch2\u003ePerformance and durability\u003c\/h2\u003e\n\u003cp\u003eIt supports a working pressure of 100 psi with a burst pressure of 300 psi, and it can withstand temperatures from -40F to 257F, providing resilience through extreme engine heat cycles and seasonal changes. The minimum bending radius of 152 mm helps reduce kinks and stress at corners in tight engine bays.\u003c\/p\u003e\n\u003ch2\u003eStandards and compatibility\u003c\/h2\u003e\n\u003cp\u003eThe hose is compatible with coolant, water, and antifreeze. It meets SAE 20R3 standard wall class D-2, aligning with common automotive cooling circuit requirements and similar systems such as hot water setups and overflow connections.\u003c\/p\u003e\n\u003ch2\u003ePractical uses and guidance\u003c\/h2\u003e\n\u003cp\u003eUse it to connect an engine cooling path to the radiator, route coolant to an overflow reservoir, or outfit a hot water heater line. The 5-foot length supports flexible routing in many layouts, while the EPDM composition aims to withstand repeated heat exposures. For best results, check for wear, avoid sharp bends, and ensure a clean, secure fit with proper clamps.\u003c\/p\u003e\n\u003ch2\u003eSpecifications at a glance\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSize: ID 3\/4 inch (19 mm)\u003c\/li\u003e\n  \u003cli\u003eOD: 1.10 inch (28 mm)\u003c\/li\u003e\n  \u003cli\u003eLength: 5 feet\u003c\/li\u003e\n  \u003cli\u003eMaterial: EPDM rubber\u003c\/li\u003e\n  \u003cli\u003eWorking pressure: 100 psi\u003c\/li\u003e\n  \u003cli\u003eBurst pressure: 300 psi\u003c\/li\u003e\n  \u003cli\u003eTemperature range: -40F to 257F\u003c\/li\u003e\n  \u003cli\u003eMin bending radius: 152 mm\u003c\/li\u003e\n  \u003cli\u003eSAE 20R3 Class D-2 compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eMedia and typical uses\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eMedium: coolant, water, antifreeze\u003c\/li\u003e\n  \u003cli\u003eApplications: hot water heater, engine cooling, radiator overflow connections\u003c\/li\u003e\n  \u003cli\u003eIdeal for automotive cooling paths and related setups\u003c\/li\u003e\n  \u003cli\u003eSupports flexible routing with reliable heat resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNote: Always verify fitment and coolant compatibility for your system before installation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What applications is the EVIL ENERGY 3\/4-inch Heater Hose suitable for?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Suitable for engine cooling connections, radiator overflow lines, and hot water heater setups using coolant or antifreeze.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What are the key specifications of this hose?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: ID 3\/4 inch (19 mm), OD 1.10 inch (28 mm); length 5 ft; EPDM rubber; 100 psi working pressure; 300 psi burst; -40F to 257F; SAE 20R3 Class D-2.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"EVIL ENERGY","offers":[{"title":"Default Title","offer_id":42467515826261,"sku":"B0BRJCZKBB","price":35.55,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/evil-energy-three-quarter-inch-heater-hose-closeup.jpg?v=1778058068","url":"https:\/\/plentytorque.co.uk\/products\/evil-energy-three-quarter-inch-heater-hose-5ft-straight-100-psi-sae-20r3-black","provider":"PlentyTorque","version":"1.0","type":"link"}
