Phenolic Bottle Caps

Four different types of quality caps add a tight seal to the wide-mouth and narrow-mouth bottles sold above. Green thermoset caps with Teflon^® Foam-Backed Liner handle a broad range of chemicals. Black phenolic caps with Pulp/Vinyl Liners enjoy wide, general use, but chemical resistance must be tested. Black phenolic caps with Pulp/Tinfoil Liners withstand solvents and seal out oxygen. White polypropylene cap No. 12799 has a film-foam liner for a tight seal. White Rubber Liner is the best autoclavable cap.

Please Add Suffix: -1 (Teflon), -2 (Pulp/Vinyl), -3 (Pulp/Tinfoil), -4 (White Rubber).
