Get to Know Keystone Cap
Founded in Lancaster County, PA in 1933, Keystone Cap has been under its present ownership since 2007. In 2009, following the acquisition of Connecticut Cap & Seal, we introduced plastisol lining to our product line.
Subsequent expansions in 2016 and 2020 more than doubled our manufacturing and warehouse space.
We honor the ingenuity and dedication of our founder by combining it with modern, streamlined manufacturing, procurement, and management practices. This approach revitalized Keystone Cap and enabled our growth into a leading multinational metal closure supplier.
Despite our expanded capacity, we remain committed to personal service and unsurpassed lead times. Whether you need a single carton or multiple pallets, custom colors, lithography, or embossing, we’re always happy to help.
Call or email us with your project requirements — we look forward to speaking with you.
And just like in 1933, you’ll always talk with a live person!
