Transportation Hoses

R149 Series
Titeflex R149 PTFE hose is designed for use with nylon-coated rigid tube per GM6405M. The inside diameter is larger than the R122 series to accomodate the nylon coated tube. Titeflex vertically extrudes innercore to maintain the highest quality of concentricity. Titeflex PTFE is manufactured from Dupont type 62 fine grade resin or equivalent and uses 304 stainless steel wire braid as reinforcement. Additionally a precisely controlled amount of carbon black added to the PTFE innercore provides a continuous conductive path to the metal end fittings, to bleed off static electricity in steam or high flow-rate applications. Vacuum service for R149 in sizes -4 through -6. Titeflex R149 operates in a temperature range of -40°F to +400°F (-40°C to +204°C) for continuous service or -65°F to +455°F (-54°C to +230°C) for intermittent service.
