Restek is pleased to offer the reusable EXP® fitting system from Optimize Technologies
for the ultimate in easy, reliable LC connections!
The patented hybrid EXP® ferrule combines the durability of titanium with the sealing
ability of PEEK for a swage that can be reused over and over again. And, when you
choose the hand-tight fitting style, the special EXP® nut offers an effortless seal up to
8,700+ psi (600+ bar)—no tools needed! For a reliable 20,000+ psi (1,400+ bar) UHPLC
connection with either fitting style, simply wrench-tighten an extra

turn.
EXP® ferrules should only be used with genuine EXP® nuts. When used with an
EXP® nut, the EXP® ferrule provides repeated ZDV (zero dead volume) connections
to any 10-32 female threaded port, including Restek® LC columns, 6-port injection
valves, and more. To accommodate varying port depths, simply hold the tubing fully
bottomed in the port and tighten as instructed.
WARNING:
Do not use EXP® ferrules with standard nuts. Failure to use EXP® fittings
according to the included instructions may result in unsafe UHPLC connections and/
or non-ZDV connections.
