High-performance Face Seal VCR Fittings | UNILOK

Image
UNILOK VCR fitting s are high-performance face seal fittings designed for ultra-high purity (UHP) applications. They deliver a reliable, leak-tight seal, making them ideal for controlling gases and fluids in critical industries such as semiconductors, pharmaceuticals, biotechnology, and analytical instrumentation. These fittings use a metal gasket placed between two polished flat surfaces to create a strong, secure connection that maintains leak-tight performance even under high pressure or vacuum conditions. Engineered for high purity environments, UNILOK VCR fittings minimize particle generation and contamination, ensuring consistent and clean system operation. Manufactured from high-quality stainless steel (typically 316L) or other corrosion-resistant alloys, they offer excellent durability and long-term corrosion resistance. The design allows for easy installation and maintenance, as components can be quickly assembled and disassembled, reducing downtime. Only the gasket nee...
