Rheodyne Style Nut and Ferrule

More Details
Replacement long nut for connecting stainless steel tubing to a Rheodyne 6-port valve or other Rheodyne part.

Nuts & Ferrules (1/16-Inch Stainless Steel)

for Valco Connectors

More Details
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.

Secure-Fit Fittings (Two Connectors)

More Details
A good connection between HPLC components is necessary for trouble-free chromatography. Secure-Fit connectors from Restek and Selerity Technologies ensure a consistent, leak-free sealand they eliminate excess dead volume! An internal spring mechanism holds the capillary tubing at the proper depth in the female fitting. This seal is maintained while you finger-tighten the nut.
