Plastic Caps | Phenolic w Foam Liner | 13mm – Black – 144 Count Discount

This 13mm Black Phenolic Plastic Cap is compatible with 13-425 thread finish vial or tube. Phenolic is more dense than polypropylene which results in a stronger rigidity when compared to a 13mm polypropylene cap, as well as a higher heat tolerance. Order today to secure product inside of vials and glass tubes with threading.

Vials, tubes and jars sold separately.

The labeling diameter refers to the usable amount of space on the top surface of a cap for a round sticker. Please note that if opening and closing instructions are included on a cap, the diameter is reduced so as to not obscure the debossed text.
