Universal PEEK connectors allow easy installation of all 1/16" tubing, including stainless steel, up to 5,000 psi.

Piston seals wear out over time and Restek is your best option for economical replacements. Choose our graphite-filled PTFE seals, which are best for organic solvents.

In-line design installs easily with standard fittings Cost-effective protection for UHPLC systems Reliable way to extend column lifetime Leak-tight to 15,000 psi (1,034 bar) Replaceable 0.5 µm stainless steel frit in stainless steel body

Allow the use of the Hub-Cap Top with GL-45 solvent bottles.

Restek’s Pack in a Box kit is a complete column-packing system. Everything you need to pack your own analytical HPLC columns is included (contents detailed below). The packing pump is electric, so no pressurized air is required. AC input requirement: 100-240 VAC, 50/60 Hz. 10,000 psi maximum…

Cost-effective protection for UHPLC systems Reliable way to extend column lifetime Universal fit—connects easily to any brand column Leak-tight to 15,000 psi (1,034 bar) 0.5 µm or 0.2 µm titanium frit in a stainless steel body with PEEK ferrule

This high-pressure cup-type filter can be used in fluid streams operating to 15,000 psi (103,421 kPa). The cup-shaped filter elements have a large (2.5 cm 2 ) surface area to give long operating lifetime. Mounted in screw-type adapters, they are easily removed for cleaning. Normally, backflushing…

Our valves have low internal volumes and are rated to 15,000 psi (103,421 kPa). They feature a two-piece stem assembly in which the rotating upper shank is coupled through a ball joint to a static lower stem. Only finger-tight torque is required to make the seal.

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