Unisource Style TSC PTFE hose is the workhorse of the industry for a variety of gas and fluid applications. Style TSC combines a smooth bore PTFE (polytetrafluorethylene) inner core with a 300 series stainless steel overbraid. A high pressure rated assembly is complete by attaching special swage type fittings made in a variety of styles.
Smooth bore, medium pressure PTFE hose is utilized in many applications, including automotive, high-pressure gas, food processing, pharmaceutical, chemical transfer, and process water. It can be found installed in gas cylinder filling plants, factories, on trucks and buses, automobiles, and a myriad of OEM equipment. PTFE hose may be the ideal solution if the application requirements exceed the chemical, heat, and other limitations of rubber, metal and plastic hose. Style TSC hose has a temperature range of -65°F to 450°F continuous service, or -100°F to 500°F intermittent service. Working pressure ratings range from 750 PSIG (-20) to 3000 PSIG (-3), depending on size, all with a 4:1 safety factor.
Some applications require a conductive inner line to dissipate static electrical charges. High resistivity fluids or gases at high velocity cause positive electrical charges to build on the inside of the PTFE liner. If not dissipated to the end of the hose, the charge will build until it arcs through the tube wall to the braid, causing catastrophic hose failure. Specify Style TSC-B with a thin conductive liner on the I.D. for static dissipation when this situation is present. When an exterior bronze braid is desired instead of the standard stainless steel braid, specify Style TSB. Style TSC PTFE hose is available in sizes 3/16” nominal to 1-1/4” nominal. Fittings options include male and female pipe, JIC/SAE female swivel, two-bolt flange, male inverted flare in straight, 45° and 90° female elbows, sanitary tri clamp, SAE 45° and 90° female swivel elbows and adapters in various standard configurations. Both swage and crimp style fittings are offered, along with reusable fittings. Materials include 300 series stainless steel, brass, and zinc or cadmium plated carbon steel. Style TSC PTFE assemblies can be hydrostatically tested prior to shipment. When specified, Unisource will hydrotest to 1-1/2 times the working pressure of the hose. Unisource also has in-house cleaning facilities for those assemblies requiring CGA level cleaning for oxygen service.
