Product Specifications

Why Choose This Reduction Adapter

Buying a whole new water pipe just to run 14mm accessories is unnecessary when a simple adapter does the job for a fraction of the cost. It creates a proper airtight seal between mismatched joint sizes for cleaner hits, and since it's fully reversible, you can remove it anytime to go back to a 19mm setup.

Ideal For

Owners of 19mm water pipes who want to use 14mm bowls or bangers, anyone building out a mixed-size accessory collection, or smokers upgrading to smaller, more common 14mm parts.

Care & Maintenance

Rinse with warm water after each use and wipe the ground-glass joint with isopropyl alcohol periodically to keep the seal airtight and free of residue buildup.
