SeCure® “Y”Connector Kits
• Connect two analytical columns to a transfer line or guard
column.
• Use standard “Y” Press-Tight® connectors and 1/16" graphite
ferrules.
• Reliable seal integrity—will not unexpectedly disconnect
during temperature-programmed analyses.
• Open design allows visual confirmation of the seal for added
confidence in the connection.
• Fit both Restek® cage designs.
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 disconnecting, even at temperatures as high as
400 °C.
Kits include: SeCure® “Y” connector body, three knurled nuts,
universal “Y” Press-Tight® union, and three ferrules.
The SeCure® “Y” connector’s open design allows
visual confirmation of the seal.
