No pressure, just perfect cleaning.

The Diff Washer by RC-Project marks a true step forward in the cleaning of differentials, bearings, and small parts for R/C models.

Unlike traditional plastic containers with metal mesh inserts, this new model stands out for its premium materials and refined design, offering superior performance, long-term durability, and virtually zero maintenance.

Weighing just 160 g, it is extremely compact and easy to handle or transport, yet its internal volume is more than sufficient to meet the needs of even the most demanding modelers.

The container and lid are CNC-machined from solid Ergal 7075, while the internal basket is made from AISI 316, a high-grade stainless steel renowned for its excellent corrosion resistance.

The Grade 5 Titanium vent screw, treated with a PVD coating, ensures exceptional wear and corrosion resistance. It allows internal vapors generated during the cleaning process to escape, ensuring optimal cleaning results without any risk of pressure build-up.

Moreover, the Diff Washer is designed to be completely leak-proof, thanks to two NBR O-rings placed on both the lid and the vent screw. These O-rings provide a perfect seal, preventing any liquid leakage even during transport or storage when filled.

The careful choice of materials, combined with meticulous attention to detail, makes the Diff Washer a versatile, practical, and reliable tool ideal for anyone looking for a professional and long-lasting solution for cleaning their R/C components.
