Graphite Ferrules for SeCure® “Y” Connectors
• Preconditioned to minimize out-gassing.
• High-purity, high-density graphite.
• Stable to 450 °C.
• No binders that can off-gas or adsorb analytes.
• Smooth surface and clean edges.
Dual-column confirmational analysis with
a single injection—one of the SeCure® “Y”
connector’ s many uses.
The SeCure® “Y” connector’s open design
allows visual confirmation of the seal.

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 pre-
vents 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, three ferrules.

Universal “Y” Press-Tight® Connectors
An alternative method of performing dual-column confirmational analyses!
• Split sample flow onto two columns—perform confirmation analysis with a
single injection.
• Split a single column flow to two detectors.
• Deactivated Press-Tight® connectors maintain complete inertness along the GC
flow path.
• Siltek®-deactivated connectors are ideal for organochlorine pesticides analysis.
• Fit 0.33–0.74 mm OD columns (Restek® 0.1–0.53 mm ID).
