VICI Caps – GL45 Threads

  • Fit all bottles or canisters with GL45 thread
  • Prevent evaporation of volatile compounds
  • 2, 3, 4, 6, or 7 ports available
  • Now available in kits for gradient HPLC systems

GL45 safety caps seal to the bottle/canister with an O-ring behind a PTFE lip, so the O-ring is therefore not a wetted part. If improved chemical resistance is required (e.g. for halogenated hydrocarbons), order an FEP-coated O-ring separately.

One port is suitable for 1/16" tubing. All other ports can fit 1/8" and 1/16" OD tubing. Unused ports should be closed with 1/4-28 plugs.


  • 1 cap, GL45 thread
  • 1 O-ring, EPDM
  • 1 set: 1/16" nut/ferrule/color-sleeve adapter
  • 1, 2, 3, 5, or 6 sets: 1/8" nut/ferrule/color-sleeve adapter

A bottom-sealing barbed adapter to connect a 1/8" (3.2 mm) ID tubing can be ordered separately.
