Vacuum-operated systems can be a pain to diagnose, and a leak can throw off the engine and everything connected to it. Make solving vacuum problems easier by picking up some of our automotive vacuum hose plugs. We have both standard rubber vacuum caps and crack-resistant vinyl vacuum caps in most sizes.

Don’t know what you’re going to need for your next project or repair? We have packages of assorted vacuum caps, so you’ll always have the right size to seal carburetor vacuum ports and to test emissions-control systems and vacuum-operated systems. We even have a carburetor-specific kit with an assortment of ⅛- to ⅜-inch ID caps.
