O-Ring Pack for Glass Ball Stems

Replacement silicone o-ring set for the Tinymight glass ball stems. The rings keep the beads and mouthpiece locked in and the stem sealed airtight; over many heat cycles they stiffen and lose grip, and a fresh set puts everything back to snug.

• Made for the Tinymight ball stems
• Brings back a tight seal and secure mouthpiece fit
• Cheap insurance - worth keeping extras around
