Choose Unisource Style TSV Convoluted Teflon Hose when you require the chemical inert, long-life properties of PTFE, but product flexibility is a prime consideration.
Style TSV combines an inner core of convoluted PTFE, externally reinforced with PTFE-impregnated fiberglass and Series 300 stainless steel wire braid. Style TSV-B hose is formulated using PTFE with carbon black additive near the tube surface. This material provides a continuous conductive path to the metal end fittings, dissipating static electricity build-up. A high pressure rated assembly is complete by attaching special swage type fittings made in a variety of styles.
This tape-wrapped, convoluted style hose is used in a variety of applications in chemical plants, food processing and pharmaceutical plants, pulp and paper mills, oil refineries, and particular O.E.M. systems. Select either conductive or non-conductive depending on the application. 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 TSV-B with a thin conductive liner on the I.D. for static dissipation when this situation is present. Specify Style TSV-HV for full vacuum applications.
