Overview
High-Pressure Compression Fitting
Engineered for demanding applications, this fitting combines robust construction with precision sealing. The design accommodates a 5/16" outer diameter tube and maintains leak-tight performance under extreme conditions, withstanding pressures up to 3300 PSI at 72°F.
Constructed from 316 stainless steel, it resists corrosion and chemical degradation, ensuring longevity in harsh environments. Its operational range spans from cryogenic temperatures as low as -425°F (-253°C) to elevated heat up to 600°F (315°C).
Designed for versatility, it integrates seamlessly with Swagelok®, Parker A-Lok, and Let-Lock systems. The double ferrule mechanism guarantees secure, vibration-resistant connections without requiring specialized tools.
Includes one complete fitting assembly for quick installation.
