Screw Thread Caps

Screw Thread Caps

Black phenolic caps with F-217 liners and cone liners are available for all screw thread vials.  Several sizes are also available in white. Sizes range from 8-425 thread to 24-400 thread.

F217 liners consist of a low density foam core between two solid layers of LDPE. This type of liner is ideally suited for use with corrosive oils, acids and solvents.

Polycone liners are ideal for applications that require an extremely tight seal. The cone shaped liner molds itself inside the vial opening creating a seal that eliminates the possibility of evaporation and leakage. This liner also provides an excellent chemical barrier.
