Exhaust Flex Pipe Common Sizes

The automotive exhaust flexible pipe produced by YDCT is mainly made by high pressure forming with water as the medium. The corrugated tube made in this way can effectively reduce stress concentration. We can also improve the flexibility of the corrugated pipe by increasing custom parameters such as corrugation height and thickness, so as to better absorb vibration from different directions, compensate installation displacement and thermal expansion and contraction, and extend the overall service life of the exhaust muffler system. As a leading stainless steel corrugated flexible hose manufacturer in China, we have manufacturing ability in material selection, size control, braiding density, welding details and other related aspects, which can meet your requirements for exhaust flex pipe customization, testing, and large quantity supply.

According to different vehicles and exhaust pipe sizes on the market, YDCT mainly supplies seven mainstream inner diameter sizes of exhaust flexible hose, which are 1.75 inch, 2 inch, 2.25 inch, 2.5 inch, 3 inch, 3.5 inch and 4 inch. The corresponding metric sizes are shown in the table below：

INCH SIZE	METRIC SIZE
1.75 inch	44.45 mm
2.00 inch	50.80 mm
2.25 inch	57.15 mm
2.50 inch	63.50 mm
3.00 inch	76.20 mm
3.50 inch	88.90 mm
4.00 inch	101.60 mm

Among them, 2 inch and 2.5 inch can basically meet the use of most common passenger cars. Of course, we can also make the related sizes based on your actual needs. The diameter tolerance of the exhaust corrugated hose we produce is generally within ±0.2–0.5 mm, and the length tolerance is within ±2–3 mm. The default wall thickness is 1.5 mm. The length depends on the exhaust pipe installation condition and connection method. Most customers choose insert welding, or use matching exhaust clamps for fixing. If you have cooperation needs or any questions, you are welcome to contact us.
