If improved chemical resistance is required (e.g. for halogenated hydrocarbons) order an FEP-coated O-ring separately. One port is suitable for 1/16in tubing. All other ports can fit 1/8in and 1/16in OD tubing. A bottom-sealing barbed adapter to connect a 1/8in (3.2mm) ID tubing can be ordered separately. Unused ports should be closed with 1/4-28 plugs. - Fit all bottles or canisters with GL45 thread - Prevent evaporation of volatile compounds - 2 3 4 6 and 7 ports available Includes: - 1 cap GL45 thread - 1 O-ring EPDM - 1 set: 1/16in nut/ferrule/color-sleeve adapter - 1 2 3 5 or 7 sets: 1/8in nut/ferrule/color-sleeve adapter
