STC FCC 1/4 N3/8 316 Stainless Steel Female Connector Compression Fitting 1/4" OD Tube X 3/8" NPT -425F to 600F Swagelok Compatible

The FCC 1/4 N3/8 316 Stainless Steel Female Connector Compression Fitting delivers robust performance in demanding high-pressure environments. Constructed from corrosion-resistant 316 stainless steel, it ensures longevity and reliability across diverse industrial applications. The fitting incorporates a precision-engineered double ferrule compression mechanism, which guarantees leak-free sealing and maintains structural integrity even under extreme pressure conditions, surpassing standard tube strength requirements.

Engineered for versatility, this connector seamlessly integrates with leading fluid system brands, including Swagelok®, Parker A-Lok, Let-Lock, and Yor-Lock. Its silver-plated nut (NTC) enhances durability and resistance to wear, while the surface-hardened back ferrule (BFC) optimizes grip and tube retention. Rated for pressures up to 4,200 PSI at 72°F, it operates reliably across a wide temperature spectrum from -425°F to 600°F (-253°C to 315°C).

Ideal for handling multiple media, the fitting supports steam, air, water, oil, gasoline, natural gas, and most solvents or acidic fluids compatible with 316 stainless steel. Its combination of precision engineering and material excellence makes it a critical component for systems prioritizing safety, leak prevention, and long-term performance.
