Sorry but this item is currently unavailable.



OPTI-LOK Fittings are ideal for high-pressure connections with 1/16” OD tubing. 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.

We realize that your time is valuable and should not be wasted worrying about fittings. For this reason, all Optimize fittings are precision machined in the USA for optimal quality and thread consistency. The machining process is the best way to ensure tight manufacturing tolerances and minimal product variance. What does all this mean? It means that every fitting you purchase from Optimize will perform just as well as the last, so you'll have no worries about faulty fittings. This reflects our commitment to providing our customers with the highest quality, best designed product available.
