Description
When maintaining the integrity of your high-vacuum environment is non-negotiable, our 704 Silicone Diffusion Pump Fluid delivers the ultimate barrier against system downtime. Engineered specifically for high-speed, deep-vacuum operations, this premium single-component fluid is optimized to withstand intense thermal stress without sacrificing throughput or contaminating your critical processes.
Constructed from pure Tetramethyl Tetraphenyl Trisiloxane , this formula serves as a direct, high-stability alternative to standard industry fluids like DC-704. Whether you are managing delicate thin-film electronics deposition or heavy-duty metallurgical furnaces, our 704 oil ensures your diffusion pumps run cleaner, cooler, and longer.
