Reliable Caps, LLC is an injection molder of high quality plastic threaded closures. For more than 45 years, our plastic caps have served an array of industries and applications, such as food, spice, condiment, sport bottle, personal care, chemical, and agricultural markets.

Centrally located in Olathe, Kansas—a suburb of Kansas City; our driving force as a company is to meet and service the needs of you, our customer. Whether you need a bulk order or just a single case of lined plastic closures for a small project, you’ll get the cap you need when you need it.

Do you have a special bottle cap in mind? If so, we’ll modify existing molds, or work with mold builders to create a custom tool for you. If you need a stock product quickly, our inventory program can likely ship your cap and liner combination the same day.

Contact us today about your project. We look forward to serving you.
