Universal Exhaust Flexible Pipe

Availability:
This flex pipe is used in exhaust and other piping systems where a certain level of flexibility is required. You will often see it in automotive exhaust assemblies, generator units, HVAC piping and similar equipment with vibration and temperature change. The pipe is formed by high-pressure water forming to create even corrugation and reduce local stress during use. Stainless steel 304 is used as standard material, with other metal grades available based on your requirement. The structure allows the pipe to handle vibration and small installation misalignment while keeping stable flow inside the system. It is commonly supplied for OEM production and aftermarket replacement. Pipe diameter, length, braid style, end type and material can be adjusted. OEM and ODM orders are accepted, MOQ starts from 50 units, with bulk packaging and basic branding available if needed.
 
 

YDCT works as a long-term exhaust component manufacturer rather than a trading supplier. Production of exhaust flex pipes is supported by in-house forming, welding, trimming and inspection lines, which helps keep batch consistency stable across repeat orders.


We are used to working with clear drawings, fixed specifications and rolling purchase schedules. For many customers, supply stability and dimensional repeatability matter more than frequent model changes, and our production setup is built around this kind of demand.


Orders are usually arranged in standard batches starting from 50 pieces, with flexible planning for ongoing projects. Samples can be prepared for fit check and evaluation before mass production. Packaging, labeling and basic boxing can be adjusted to match your internal handling or warehouse requirements.Communication is kept straightforward. Technical details, tolerance limits and production feasibility are discussed before order confirmation, so later changes and rework can be avoided.


Our manufacturing capacity exceeds 350,000 units per month, supporting both OEM and aftermarket production demands.For buyers managing high-volume procurement or system design, these pipes offer reliability and repeatable quality at industrial scale. They are especially effective in applications requiring flexible connections between rigid exhaust elements—such as catalytic converters, mufflers, or DPFs—and the engine manifold.
