Didde Web Press Roller 327-555

The Didde Web Press Roller 327-555 is a precision-recovered Water Pan Roller for the Triflow dampening system on the Didde ML1000, Didde 860, and Didde Model 20.5″ web offset printing presses. Part number 327-555, this roller also matches Lith-O-Roll part number DG-329-15-B, providing a compatible replacement for presses originally equipped with either brand. The water pan roller is the starting point of the Triflow dampening chain — it picks up fountain solution from the pan and feeds the metering system, so its surface condition directly determines how consistently fountain solution enters the dampening circuit on your Didde press.

A worn or contaminated water pan roller on a Didde Triflow system delivers an uneven or excessive film of fountain solution, upsetting the ink-water balance and causing problems such as scumming, toning, ink emulsification, and inconsistent dot reproduction. Replacing a worn 327-555 with a precision-recovered unit restores controlled, even moisture pickup, helping your Didde ML1000, 860, or 20.5″ maintain stable dampening throughout the press run and reduce waste from ink-water imbalance issues.

Please verify the part number prior to ordering — many Didde models share rollers that may be interchangeable across configurations, and confirming the correct part number ensures you receive the right dampening roller for your specific press.
