SGE HPLC Unions are specifically designed and precision engineered for use in capillary LC

• Zero dead volume design for no peak dispersion
• Easy to use
• Complete versatility
• Allows connection to the same or different sized tubing
• Available in PEEK and stainless steel

Stainless steel unions can be finger tightened or tightened with a 3/16" wrench for high-pressure applications. PEEK unions can be finger tightened. They are slightly larger than stainless steel unions, but they are lighter for less stress on your tubing. Pressure rating is 5000 psi for the stainless steel unions and 2175 psi for the PEEK unions.

ProteCol™ Unions and reusable PEEK ferrules allow you to connect any combination of 1/32" PEEKsil™, 1/16" PEEKsil and 0.36 mm fused silica tubing. Use for connecting guard or trap columns to analytical columns, or for bypassing the analytical column.

The ideal way to avoid any void or dead volume in a connection is to achieve a faultless butt connection
