Marina Opal Top Cap For Towers And Slupers

Top Caps for Towers and Terp Slurpers. Each cap is made from solid US borosilicate glass and features a beautifully shaped body with an encased opal at the top of the handle for extra visual pop. The extra-long base creates a strong, reliable seal, helping prevent the cap from falling off your slurper during movement—unlike marbles that can roll off.

It fits 16-22mm top OD bangers, such as Towers, Terp Slurpers, Terp Slides, etc. If using this with a terp slurper means you cannot use a middle-valve marble – the cap’s long base is too long for both.

Specs: Top Cap has a 31mm wide disk. The top has a 10mm wide base/tip, so the banger must have an 11mm ID opening for the top to fit.
