Constructed with a polyester braid reinforcement and a smooth silicone jacket, it delivers greater heat and aging resistance than standard EPDM hoses while remaining flexible and easy to work with. The coil format lets you cut the exact length needed for repair or fabrication without buying multiple preformed lines.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this hose handle high temperatures and pressure?\u003c\/h3\u003e\n\u003cp\u003eThe Outus silicone hose is engineered for demanding temperature and pressure ranges, operating reliably from -40°F up to 230°F (-40°C to 160°C) and rated for working pressures up to 85 PSI (burst around 170 PSI). Its silicone compound resists hardening and cracking under repeated heat cycles while the internal braid keeps strength and shape under pressure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTemperature range: -40°F to 230°F (-40°C to 160°C)\u003c\/li\u003e\n  \u003cli\u003eWorking pressure: up to 85 PSI; burst ≈ 170 PSI\u003c\/li\u003e\n  \u003cli\u003ePolyester braid reinforcement for dimensional stability\u003c\/li\u003e\n  \u003cli\u003eMaintains flexibility under heat load\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this hose fit my vehicle or plumbing needs?\u003c\/h3\u003e\n\u003cp\u003eThis is a 3\/4\" nominal heater hose with an actual inner diameter of 19 mm and an outer diameter of 27 mm, supplied as a continuous 25-foot roll so you can trim custom lengths.
