Riverport Technologies is proud to provide the finest dielectric fluids currently available for all your manufacturing needs.

Rustlick EDM-500
High Performance Dielectric Oil

A synthetic transparent fluorescent green dielectric fluid formulated from base chemicals so highly refined and purified that additional additives are not necessary. EDM-500's cosmetic-grade chemical formulation virtually eliminates skin irritation during use. Resists thermal degradation from high-amperage applications (withstands up to 400 amps) and offers the highest known dielectric strength of any commercially available EDM fluid. EDM-500 can be used with all types of filters; including: paper cartridge, diatomaceous earth, and edge wafer disposable cartridges.

Rustlick EDM-250
Dielectric Oil

Designed to resist thermal degradation from high-amperage applications, EDM-250 is the longest lasting dielectric oil available - often lasting up to 3 years or more. It has low viscosity for excellent flushing and finishing, and prevents the clogging of diatomaceous earth and edge-wafer disposable cartridge filters. EDM-250 eliminates the smoke and odor associated with cheaper, less-refined oils.

Rustlick EDM-30
Dielectric Oil

A high-quality oil, EDM-30's low viscosity allows for fast settling and simplified purification. This yields higher quality finishes. EDM-30 eliminates smoke and odor and is designed for paper cartridge filtration up to 150 amps.
