Highlights
- Three sizes in one pack: 35mm, 47mm, and 72mm caps cover the most common bowl openings, tube diameters, and mouthpiece sizes found on standard water pipes and rigs.
- Flexible silicone construction: Each cap stretches to fit over irregular openings and creates a firm seal that holds during vigorous shaking.
- Cap over openings (vs. plug into them): Unlike plug sets that go inside the joint, these caps fit over the outside of the opening — useful for tubes and mouthpieces that are too wide for standard plugs.
- Keeps solution inside, mess outside: Apply caps before shaking cleaning solution through your piece — no spills, no wasted cleaner.
- Reusable: Rinse after each use. Silicone caps are durable across many cleaning sessions.
In the Box

Description
Randy's Black Label Cleaning Caps are a three-pack of flexible silicone caps sized to fit over the openings of standard water pipes during cleaning. The 35mm, 47mm, and 72mm caps cover a broad range of tube diameters and mouthpiece sizes — cap your piece's openings before adding cleaner, shake, and the solution stays exactly where it needs to be. Each cap is reusable and rinses clean in seconds.
Unlike plug sets that insert inside a joint, these caps fit over the outside of the opening, making them well suited for mouthpieces and bowl holes that are too wide for a standard silicone plug. The silicone material stretches enough to accommodate slight variations in diameter while maintaining a firm seal under shaking. Three caps are included — enough to seal the primary openings on most bong setups simultaneously.
FAQs
- What is the difference between caps and plugs? Plugs go inside the joint and expand to seal it. Caps fit over the outside of the opening — better for wider openings like tube mouthpieces or bowl holes that exceed standard plug sizes.
- Will these fit my bong? The 35mm, 47mm, and 72mm sizes cover most standard bong tube openings. Measure your openings before purchase if unsure.
- Are these reusable? Yes — silicone caps hold their shape and seal quality across repeated use. Rinse after cleaning.
- Do I need both caps and plugs? For a complete seal on all openings (joints + tube), using caps on the wider openings and plugs in the joints gives the most complete coverage.
