In this section, we would like to assist you with the selection of the appropriate hose for exhaust gas extraction. In the following, we have compiled an initial selection of the most suitable hoses from our range of hoses for exhaust gas extraction. The products listed here are suitable for use in workshops for exhaust gas measurement, on engine test benches and exhaust systems for the vehicle sector. For further information about our range of exhaust gas hoses see below.
Hoses for exhaust gas extraction
Applications and properties
The exhaust gas hose is a flexible hose that is used to route exhaust gases from vehicles and other devices away from the operator. It is mainly used in vehicle exhaust gas systems, overhead and underfloor extraction systems and engine test benches in industry and workshops. In order to guarantee smooth and error-free use, the hoses must have certain properties. For example, hot gases up to several hundred °Celsius have to be transported without damaging the material. Also a flexible hose form is advantageous in order to withstand vibrations and impacts from outside.
The following of our hose products meet these requirements and can be safely used for the transport of exhaust gases:
• PROTAPE® TPE 325 WEAR STRIP
• PROTAPE® TPE 326 MEMORY
• METAL HOSE 375
• CP HYP 450 and CP HYP 450 PROTECT
• CP ARAMID 461 and CP ARAMID 461 PROTECT
• CP KAPTON® 476
• CP HiTex 481, 483, 485, 486 and 487
Frequently asked questionsUp to what maximum temperatures can the hoses be used?
• up to 120°C: METAL HOSE 375
• up to 170°C: CP HYP 450
• up to 200°C: PROTAPE® TPE 326 MEMORY* and CP HYP 450 PROTECT*
• up to 220°C: PROTAPE® TPE 325 WEAR STRIP
• up to 300°C: CP ARAMID 461 and CP ARAMID 461 PROTECT*
• up to 400°C: CP KAPTON® 476
• up to 500°C: CP HiTex 487
• up to 550°C: CP HiTex 485
• up to 700°C: CP HiTex 481 and CP HiTex 486
• up to 1100°C: CP HiTex 483
*when correctly applied with exhaust gas funnels and sufficient fresh air supply (50% approx.)
Typical application areas are the use in hose reels, floorgrid and underfloor extraction systems for the suction of exhaust gases as well as the exhaust gas measurement in vehicle exhaust systems. All hoses listed in this category are suitable for the aforementioned applications, in which the crush resistance of the PROTAPE® TPE 326 MEMORY or the abrasion protection via external clamp profile of the CP HYP 450 PROTECT and CP ARAMID 461 PROTECT are advantageous in car workshops. On the other hand the CP HiTex 485 and CP HiTex 486 are insulating and thus suitable for slight overpressure.
