If you aren't looking at a pneumatic valve, you might be looking at a specialized automotive part or a heavy-duty fastener.

In a manufacturing context, the numbers following the prefix usually denote the piston diameter (bore) and the stroke length. A "426" designation often points to a custom or specific configuration within the ISO 21287 standard.

Some aftermarket brake pads or rotors use alphanumeric codes similar to ADN-426 to categorize fitment for specific Japanese or European car models.

For pneumatic versions, the "C" might indicate a specific seal material (like Viton for high heat). Ensure your replacement matches the environmental needs of your facility.

Usually constructed from anodized aluminum or reinforced polymers to resist corrosion.

If you are tasked with replacing an ADN-426 C component, keep these tips in mind:

The "ADN" line is known for being up to 50% smaller than standard cylinders, making them ideal for tight spaces.
