Optimize Technologies OPTI-LOK 6K Nuts + Frrls 10PK 10-20-00270 FREE S&H . Optimize Technologies High pressure liquid chromatography HPLC columns.

Opti-Lok fittings are ideal for making high-pressure connections with 1/16 OD tubing. -Precision machined -Optimal quality and thread consistency -Trouble-free operation at high pressures All Optimize fittings are precision machined for optimal quality and thread consistency, and are designed for trouble-free operation at pressures of up to 6,000 psi. Opti-Lok LP Fittings are an excellent choice for making low-pressure connections into 1/4-28 ports. Connections to flat-bottomed ports can be made using Opti-Lok flat-bottomed ferrules for 1/16 or 1/8 tubing, without the need for pre-flanged tubing ends. Opti-Lok LP fittings are precision machined to deliver leak-free, zero-dead-volume connections every time. Also available are 1/4-28 unions in various through-hole sizes for joining flatbottom fittings together. Opti-Lok Adapters offer maximum flexibility for making connections between your 1/4-28, M6 (Metric), Luer and 10-32 fittings and ports. They are available in a useful variety of thread-type combinations, all precision machined from PEEK.
