EXP2 – the next generation of EXP UHPLC fitting technology. Featuring a small 3/16” hex-head EXP®2 nut, the new EXP®2 Driver and the original titanium hybrid ferrule, the EXP2 fittings offer hand-tight connections rated to 20,000 psi+. The EXP2 nuts are available with 6-32, 6-40 and 10-32 threads and have been scaled down to allow for maximum working room in cramped spaces. The EXP2 Driver is a small, easy to use knurled torque driver which snaps on to the nuts for hand-tightening and loosening. The EXP2 Driver is slotted and can be removed from the nut and tubing after use.
