High Purity Union
The High Purity Union is a precision-engineered connector designed for reliable and contamination-free joining of two high-purity pipes or fittings. It allows easy installation, maintenance, and disassembly without cutting or welding the pipeline. Manufactured from high-purity materials such as PVDF HP, PFA, or PP-H HP, the union ensures exceptional chemical resistance, smooth internal flow, and minimal particle generation.
These unions are commonly used in ultra-pure water systems, semiconductor fabrication, pharmaceutical processing, biotechnology facilities, and high-purity chemical distribution networks. The design includes a strong union nut, precision sealing surfaces, and an O-ring (EPDM, FKM, or PTFE-encapsulated) to ensure a tight, leak-proof connection.
High Purity Union
- High-purity construction ensures zero contamination and ultra-clean fluid transfer.
- Easy installation and disassembly with a threaded union nut for maintenance-friendly operation.
- Superior chemical resistance to aggressive acids, bases, solvents, and UPW.
- Ultra-smooth interior surface reduces particle shedding and prevents bacterial growth.
- Secure leak-proof sealing with high-quality O-ring options.
- Lightweight, corrosion-proof, and long-lasting for demanding environments.
- Available in multiple sizes and configurations including weld end, socket fusion, or grip-type ends.
- Cleanroom-molded components meet strict industry standards (SEMI, ASTM, DIN).
