These flexible exhaust pipe fittings have a 304 stainless steel braided shell and also contain a liner with some double-layer flexible stainless steel bellows and end caps. Braided stainless steel flexible exhaust pipe fittings are ideal for reducing exhaust system vibrations and also act as a muffler.
We understand that many flexible exhaust pipe fittings on the market today have poor corrosion resistance.Our braided flexible exhaust pipe fittings are based on experience.To meet daily driving conditions, can withstand the vibration and stress of the exhaust system, and have excellent corrosion resistance.So from the top cover to the body to the bellows and liner, it is 100% 304 stainless steel.
Regarding the interlocking liner, as an innovative existence, it helps to make the hot exhaust gas flow smoothly and pass through the flexible coupling. The interlocking liner is completely smooth and flat, it provides straight-through exhaust gas flow and does not intrude into the inner diameter of the braided flexible exhaust pipe coupling, nor is it reduced internally.
The inner diameter of the braided flexible exhaust pipe coupling we can provide ranges from 1.5 inches to 3.5 inches, and the length is 6 inches to 10 inches, which can also be customized according to your needs.
All of our internally braided flexible couplings have the same braided inner layer as the interlocking flexible couplings, which helps eliminate "whistling" and prolong the service life of the metal exhaust bellows. Internally braided flexible couplings facilitate stable flow of hot exhaust gases through the flexible coupling. In the smaller size range, the inner braid is almost stable and smooth and does not protrude into the interior of the flexible coupling. It should be noted that in the larger size range, the inner diameter is usually 3.5 inches and 4.0 inches, and the inner braid will protrude into the interior of the flexible coupling, so that the overall inner diameter of the flexible coupling can be reduced. The inner diameter of the internally braided bushing flexible couplings we provide ranges from 1.750 inches to 4.000 inches, and the length ranges from 4 inches to 10 inches or can be customized according to drawings.
Interlocking bushing and internal braided styles are included in the external braided flexible couplings,They are an excellent choice for OEM replacement applications including exhaust system applications.Flexible couplings are durable and economical and are an excellent choice for new exhaust systems and replacement parts;
It should be noted that they are not suitable for pre-turbo applications. The reason is that the turbocharger or manifold will generate extreme heat, and then the internal braided part or interlocking bushing will degrade and damage the turbocharger.Our recommendation is to use a flexible bellows with a solid liner for pre-turbo applications.
