The AIO Fitting incorporates all of the EXP™2 Ti-LOK features with one distinct difference: a permanently-fixed driver. When tight spaces are not an issue, we recommend using the AIO Fitting. EXP™2 Fittings with Integral Ferrules offer LC connections that can be hand tightened to 18,000+ psi (1,250+ bar). These are ideal for making HPLC and UHPLC connections that easily fit into tight spaces such as injection valves, column couplers, sample loops and column ovens. The AIO Fittings feature built-in PEEK ferrules and threaded nuts precision machined from titanium. AIO’s combine the superior corrosion resistance and robustness of titanium with the sealing capability of PEEK. The fitting also creates zero-dead-volume connections and the ferrule does not permanently swage to the tubing, allowing for many repeat connections and the ability to adjust the tubing to different port depths. Compatible with PEEK, PEEKsil™, Hastelloy C and stainless steel tubing.
