Our experienced team can custom make any assembly configuration with the use of various fittings or flanges. Call us for best prices for annular corrugated metallic flexible hose with PTFE lining – 1/4″ ID to 8″. As a reputed supplier to many oil and gas, petrochemical and paper manufacturing companies, all our PTFE hoses are 100% leak tested.Polytetrafluoroethylene (PTFE) is an engineered fluoropolymer. Outstanding resistance to chemicals is one of its primary attributes. A broad temperature range of -100°F to 500°F (-73°C to 260°C) make this hose material suitable for the majority of fluid and ambient temperature conditions found in industry. An extremely low coefficient of friction, (0.05 to 0.20), provides a non-stick surface. Water absorption of PTFE is negligible, less than 0.01% by ASTM test, and it is FDA-approved for food and pharmaceutical use. Additionally PTFE will withstand flexing and vibration without failure from flex fatigue. PTFE is chemically inert, it will not break down or deteriorate in service and it has an unlimited shelf life because properties do not change with age or exposure to weather.PTFE hoses maintain high strength, toughness and self-lubrication at low temperatures down to 5 K (−268.15 °C; −450.67 °F), and good flexibility at temperatures above 194 K (−79 °C; −110 °F)PTFE Hose Pipes with Flange Fittings – Round Flange, Square Flange, Custom FlangesPTFE Hose Pipes with Union Fittings – Stainless Steel, Carbon Steel, Mild Steel, Brass, CopperPTFE Metal Hose Pipes with Threaded Fittings – BSP, BSPT, NPT, UNUF, JICPTFE Metal Hose Pipes with Tri Clover – TC Ferrule, Tri Clamp, GasketsPTFE Metal Hose Pipes with Camlock & Quick Release CouplingsPTFE Metal Hose Pipes with Pipes, Elbows, BendsPressure Ratings & Technical Specifications for Smooth Bore PTFE HosesStainless Steel PTFE Hose SAE 100 R14Temperature : -54Deg.
