Tubing & Connections

• Precut, micropolished tubing and preseated fittings for quick, easy maintenance of your Agilent HPLC systems.
• Meet or exceed manufacturer's performance.

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

• 316 grade stainless steel.
• Precise pre-cut lengths.
• Smooth surface finish.
• Ultra clean.

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 seal—and 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. These fittings are available in stainless steel or PEEK, and in a variety of tubing lengths and internal diameters.

Restek offers stainless steel tube fittings to help you maintain your HPLC equipment. Parker’s A-Lok™ two-piece ferrule design, along with NPT fittings, are ideal for modifying existing instrumentation or replacing worn connections.

Opens stainless steel tubing bore and removes burrs. For 1/16-inch OD tubing or 1/8-inch OD tubing.

• Burr-free, perpendicular cuts that will not distort the tubing OD or close the ID.
• Use on PEEK, Teflon®, Tefzel®, other polymeric tubing.

Quickly and reliably connect two pieces of 1/16-inch tubing. 0.3 mm union bore. End fittings included.

Universal PEEK Connectors allow easy installation of all 1/16-inch tubing, including stainless steel.

Tubing Elbows (90° and 180°) are ideal for routing 1/16-inch PEEK tubing through your system. Simply snap the tubing into the elbow. Prevent pinching of PEEK tubing which can cause high pressure.

Securely holds 1/16-inch or 1/8-inch tubing in beaker, flask, or bottle up to 4 mm thick.

• Ideal for mobile phase inlet lines.
• Chemically inert.
• Use to 500 psi (3,447 kPa) and 80 °C.

• Replaces stainless steel, titanium, Teflon® or Tefzel® tubing.
• Less oxygen permeable and more temperature resistant (to 250 °C) than Teflon® or Tefzel® tubing.
• Use with PEEK fingertight or flangeless fittings.
• Use to 7,000 psi (48,263 kPa).

Ends of tubing seat squarely at bottoms of fitting details. 300 series stainless steel. For 1/16″ OD tubing. Stainless steel ferrules included.
