STC CUC 1 316 Stainless Steel Cross Union Compression Fitting 1" OD Tube 1900 PSI -425F to 600F Swagelok Parker A-Lok Compatible

CUC 1 316 Stainless Steel Cross Union Compression Fitting delivers robust performance in high-pressure industrial and laboratory environments. Engineered with a double ferrule configuration, this fitting ensures secure, leak-free connections while maintaining resilience against vibrations and mechanical stress.

The body is crafted from corrosion-resistant 316 stainless steel, complemented by a silver-plated nut and a surface-hardened back ferrule for enhanced durability. Designed to accommodate 1" outer diameter tubing, it operates seamlessly across extreme temperature conditions, from cryogenic environments as low as -425°F (-253°C) to high-heat scenarios up to 600°F (315°C).

This fitting supports compatibility with leading fluid system brands, including Swagelok® and Parker A-Lok, making it adaptable for diverse installations. It is ideal for handling steam, compressed gases, hydrocarbons, and chemically aggressive fluids compatible with 316 stainless steel. Rigorously tested to exceed tube failure thresholds, it guarantees reliability even under peak pressure loads of 1,900 PSI (131 bar).
