28-410 Ribbed Black Plastic Cap (F217 Liner)

28-410 black ribbed cap with F217 liner.  This lid is made of polypropylene. The ribbed feature provides extra grip when applying or removing the cap. The F217 liner creates a seal that is great for dry products.  F217 liners are not typically recommended for liquids and oils.  These lids match nicely with our 28-410 plastic bottles.
