MOCAP is a manufacturer, therefore many of the customized items we offer are only available in larger industrial-sized quantities and typically have a 500-5000 piece minimum order quantity. The drop-down list on this page will show which quantities are offered.

If an item is stocked, we usually offer it in smaller "minipack" or "micropack" quantities. But, MOCAP does not stock every diameter/length/color that we can produce. If a particular custom item you are looking for is only offered in a larger quantity than what is required, try searching our site for a comparable stock item in a different color, or look for similarly-sized stock items that may also work for your application.

MOCAP Threaded Plastic Plugs are designed for use on Straight Thread O-Ring Ports. These Threaded Plastic Plugs are knurled for easy use in manual assembly and removal.

They provide positive seal on SAE Straight Thread O-Ring type ports and MIL-MS-33649 bosses. Integrated O-ring type bead seats in the bevel of the port to prevent entrance of debris or contaminants and oil leakage. Seal at outside of knurl protects port face against paint and dirt.
