Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).
Typical settings include semiconductor equipment, aerospace, and high-temperature process equipment.
This item is sold individually under part number V75351. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
