StockCap manufactures a complete line of rubber stoppers including both tapered and pull-through designs as well as lower cost stoppers/plugs made from flexible vinyl and rigid plastics.
Additional Rubber Plugs
Beyond the traditional Tapered Plugs, are Pull Plugs available in both EPDM and Silicone materials. The unique trait of the pull plug is activated when pulled through a hole, stretching it so as it is released it tightens and secures the seal. Later, when its service is complete, another pull stretches it, reducing the friction and allowing it to be removed. These pull plugs are re-useable in some situations. View our Material Selection Guide for details.
Additional Plastic Stoppers
Plastic stoppers offer a cost effective alternative to rubber stoppers for some applications. In particular, our vinyl plus plugs have a lot of the same characteristics as the rubber stoppers in terms of flexibility and the seal that they provide. Our plastic T-Plugs also function great as protectors against dust or particle contamination.
