The LiteTouch PEEK Ferrule is specifically designed to be part of a system that helps prevent the twisting of polymer tubing by gripping tubing at two compression points. It can be used with hard tubing material like stainless steel and PEEK preventing the collapse of tubing ID. It is designed for 1/8"OD tubing.
LiteTouch Fittings are specifically designed to effectively grip tubing at two compression points, holding to high pressures with Fingertight convenience. It also prevents polymer tubing from twisting, a potential problem when using standard Fingertight fittings. To avoid collapsing the ID of your tubing, the LiteTouch system can be used on hard tubing only, such as stainless steel and PEEK polymer tubing. The LiteTouch Ferrule System is not recommended for repeated use in plastic ports.
