Reliable Connections Made Simple
by Donna Lidgett, GC Accessories Product Marketing Manager
SeCure™ “Y” Connectors
Connect two analytical columns to a transfer line or guard column.
Combine the simplicity of a “Y” Press-Tight® connector with the strength of a metal union. The ferrules
and knurled nuts hold the fused silica tubing in place, which prevents the tubing from unexpectedly dis-
connecting, even at temperatures as high as 400°C.
Kits include: SeCure™ “Y” connector body, 3 knurled nuts, 1“Y” Universal Press-Tight® union, and 3 ferrules.
The Vu2 Union™ connector’s open design allows
visual confirmation of the seal; secondary seals
ensure a leak-tight connection.
