Products
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. View Product Information
Universal Press-Tight^® Connectors Connect a guard column to an analytical column. Repair a broken column. Connect a column outlet to a transfer line. View Product Information
Universal Angled “Y” Press-Tight^® Connectors Perform confirmation analysis with a single injection. Made from inert fused silica. Inlet and outlet ends conform to the column curvature—alleviates column-end connection strain. View Product Information
MXT^® “Y”-Union Connector Kits for Fused Silica Columns Low-dead-volume, leak-tight connection. Reusable. Siltek® treatment ensures maximum inertness. Ideal for connecting a guard column or transfer line to an analytical column. Use to oven temperatures of 360 °C. Available in union and “Y” configurations. Can also be used for fused silica to metal connections. View Product Information
Zero-Dead-Volume Valco^® Internal Union Ends of tubing seat squarely at bottoms of fitting details. 300 series stainless steel. For 1/16″ OD tubing. Stainless steel ferrules included. View Product Information
Vu2 Union^® Connectors Connect a guard column to an analytical column. Connect a column to a transfer line. Connect two columns in series. Repair a broken column. Fit both Restek cage designs. View Product Information
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. View Product Information
MXT^® Low-Dead-Volume Connector Kits for Metal Columns Connect a guard column/transfer line to an MXT® stainless steel column. Low thermal mass tracks rapid oven temperature programming. Stainless steel ferrules and nuts. Available in “Y” and union configurations. Siltek® treatment ensures ultimate inertness. Each kit contains the MXT® union, two 1/32-inch ferrules and nuts.

MXT^®-Union Connector Kits for Fused Silica Columns Low-dead-volume, leak-tight connection. Reusable. Siltek® treatment ensures maximum inertness. Ideal for connecting a guard column or transfer line to an analytical column. Use to oven temperatures of 360 °C. Available in union and “Y” configurations. Can also be used for fused silica to metal connections. View Product Information
Vacuum Vu-Union^® Connector for GC/MS Applications Connects analytical column to MS transfer line. Use under vacuum conditions. Use only with Vu-Union® Vespel®/graphite ferrules (order ferrules separately). Includes metal housing body, one deactivated tapered glass insert, and Vu-Union® Helping Hand. Fits column ODs from 0.33–0.74 mm (Restek 0.1 mm–0.53 mm ID). View Product Information
Zero-Dead-Volume Valco^® Internal Cross Connect four lines. 300 series stainless steel; stainless steel ferrules included. For 1/16″ OD tubing. View Product Information
Zero-Dead-Volume Valco^® Internal Tee Connect three lines. 300 series stainless steel; stainless steel ferrules included. For 1/16″ OD tubing. View Product Information
Zero-Dead-Volume Valco^® Internal Reducing Union Connect two sizes of tubing, using zero-dead-volume fittings on each end. For 1/8″ to 1/16″ OD tubing. Stainless steel ferrules included. View Product Information
MXT^® Low-Dead-Volume “Y” Connector Kits for Metal Columns Connect two MXT® columns to one inlet or one MXT® column to two detectors. Each kit contains the MXT® union, three 1/32-inch ferrules and nuts. View Product Information
Universal Angled Press-Tight^® Connectors Ideal for connecting a guard column to an analytical column. Made from inert fused silica. Angle approximates the curvature of a capillary column, reduces strain on column-end connections. View Product Information
Polyimide Resin Securely connects a Press-Tight® connector to a fused silica column. View Product Information
GRAPHPACK^® 3D/2 Ferrules
GRAPHPACK^® 2m Ferrules
Nuts & Ferrules (1/16-Inch Stainless Steel) for Valco® Connectors Restek offers a selected line of Valco® fittings for connecting fused silica or 1/16- or 1/8-inch metal tubing. Valco® fittings have been designed for the specific demands of instrumentation and manufactured with the tight tolerances and premium quality that analysts require. If you don’t see the Valco® fitting you need, please request special ordering information. View Product Information
1/16-Inch Valco^® Adaptor Ferrules Fused silica adaptor ferrules are Valcon polyimide, a unique graphite-reinforced composite, specially prepared to maximize mechanical stability at temperatures to 350°C. The determining factor for selecting adaptor ferrule size is the fused silica tubing OD. View Product Information
1/32-Inch Valco^® Adaptor Ferrules (Valcon Polyimide) Fused silica adaptor ferrules are Valcon polyimide, a unique graphite-reinforced composite, specially prepared to maximize mechanical stability at temperatures to 350 °C. The determining factor for selecting adaptor ferrule size is the fused silica tubing OD. View Product Information
