PTFE Smooth Bore Standard

Smooth Bore Automotive Applications

Smooth Bore Specification

 

Temperature Resistance : PTFE hose is usable from -70°C up to +260°C,

dependent upon the braid and the working pressure (see specification tables)

Chemical Resistance : PTFE is the most chemically resistant material know and is only affected by small number of very uncommon chemicals; Fluorine Gas, boiling Alkali Metals, Chlorine Trifluoride and Oxygen Difluoride.

Flexibility with Strength : Smoothbore PTFE hose has excellent dynamic flex life and performs well at high pressures in flexing or vibrating applications.

Self Cleaning : The famous non stick nature of PTFE ensure that material passing through does not become ‘hung up’ inside the hose, creating the risk of bacterial growth or contamination. The hose, therefore is effectively self cleaning.

Smoothbore PTFE hose on Reels : All hose specifications are supplied in random production lengths, either in coils or on reels for customers to assemble hoses using their own end fittings. If specific lengths are required, please contact your hose supplier. Stainless steel braided hose can be supplied specially cleaned and degreased if required, with all traces of oil removed from the braid.

Smoothbore Hose Assemblies : Smoothbore hose can also be supplied in the form of made up assemblies with end fittings attached by machine crimping at each end. Normally, 10% of all assembles are hydrostatically pressure tested to 1.5 times the maximum working pressure. More extensive testing of the hoses is also possible, as is pneumatic (air under water) testing.
