48R503 - Walter Viton Seal Ring 12mm x 2mm

High-Performance Sealing with the Walter 48R503 Viton O-Ring

The Walter 48R503 O-Ring is a critical replacement component designed to maintain the integrity and efficiency of your Walter Surface Technologies equipment. Engineered from premium Viton (FKM), this O-ring provides a robust sealing solution that far outperforms standard rubber or neoprene alternatives, particularly in demanding industrial environments. With precise dimensions of 12mm x 2mm, it ensures a perfect fit for specific connection points within Walter's fluid handling or electrochemical cleaning systems.

Why Choose Viton?

Viton is a synthetic rubber and fluoropolymer elastomer known for its exceptional resistance to extreme conditions. In the context of Walter equipment, which often involves the use of electrolytes (such as in Surfox weld cleaning systems) or industrial cleaners (like Bio-Circle), the chemical resistance of the seal is paramount. The 48R503 resists degradation from:

• Aggressive chemicals and acids


• Oils, fuels, and lubricants


• High operating temperatures


• Oxidation and ozone exposure

By utilizing this genuine Viton part, you prevent premature seal failure that could lead to hazardous leaks, pressure drops, or contamination of the workspace.

Maintenance and Compatibility

Regular maintenance of industrial machinery is essential for safety and longevity. O-rings are wear items that eventually degrade due to compression set and environmental exposure. Replacing worn seals with the authentic 48R503 ensures that your equipment continues to operate at factory specifications. This part is manufactured to the exact tolerances required by Walter Surface Technologies, eliminating the guesswork and potential risks associated with generic, ill-fitting aftermarket seals.

Installation and Performance

Installing the 48R503 is a straightforward maintenance task that restores the airtight or watertight security of your system. Its durability means longer intervals between service, reducing downtime and maintenance costs over the lifespan of the machine. Whether you are repairing a wand connection, a pump fitting, or a tank seal, this O-ring delivers the reliability professional fabricators and maintenance teams expect from the Walter brand.
