Analytical Heating Hoses
250 °C
Series H 300 C
Analytical heating hose with replaceable
inner cores and screw fi tting
Applications:
Maintaining the temperature of probe lines for engine exhaust
gases, CO

measurements, industrial waste gases, blast furnace
waste gases, air measurements, etc.
The special fi ttings of 1.4571 steel prevents migration and buckling
of the PTFE core at the ends of the analytical heating hose. A cut-
ting ring screw union can be fi tted. The external braiding provides
tension relief.
