Frequently Asked Questions


How Do I Purchase Maxicaps?

Our Maxicaps can be purchased through our North American distributor, Minvalco.  Minvalco has four locations, and can be reached at http://www.minvalco.com/ContactUs.aspx

Will Maxicaps Void My Regulator Warranty?

Maxicaps do not change the form, fit, or function of any regulator, they are simply a protective cover.  More importantly, it is a violation of United States federal law for a manufacturer to require a consumer to purchase their protection products to maintain your warranty.  For more information, visit our home page to learn about the Magnuson-Moss Act.

What are Maxicaps Made of?

Our MC-3s are made of vulcanized rubber, while both our MC-5s and MC-7s are made of dipped plastisol.
