Metal Substrate

Why Metal Substrates with Integrated Flanges Work Better

1.4em; text-align: left;">Lately, more DOC and DOC+DPF systems are using metal substrates with integrated flanges. It’s not just a design trend — it actually makes life easier in the field.

1.4em; text-align: left;">Sealing is solid. Since the flange is part of the substrate, alignment problems are mostly gone. On the line, installation is simple: drop it in, line up the bolts, tighten, done. Fewer leaks, less rework.

1.4em; text-align: left;">Thermal stability. Heat cycles cause less stress, and the coating stays put. Everything lasts longer.

1.4em; text-align: left;">Same footprint, more reliability. The external size doesn’t change, but the built-in flange keeps everything lined up and stiff. The result: longer life and predictable performance.
