Do they make silicone vaccum caps?

I've been using cheapo autozone rubber vaccum caps to cap some unused vacc nipples..but these peaces of sh*t are dry rotting in a matter of several months.

Is there a better alternative? Something that will last a bit longer? Better rubber, or silicone vacc caps? I'm not interested in using JB weld or anything permanent like that.

Which vacuum caps from autozone are you using? The standard black rubber or the colored ones from the performance isle ( the one with all the chrome stuff for V8s)?

Go with the colored ones ( i think they are silicone) at autozone. The package has a few different sizes and they last along time.

The cheap rubber vacuum caps aren't made to stand up to the heat of our engines. Maybe with a heat wrapped header they could... but I know with my stock manifold they go bad quick . I just had to replace 3 with under 2,000 miles on them.
