14mm Quartz Cap (Terpedo) – Compact chamber, roughly 0.2 g capacity. Ideal for solo sessions, micro-dosing, or smaller rigs. Heats up quickly and provides efficient personal use.

18mm Quartz Cap – Larger chamber, about 0.5 g capacity. Best for heavy hitters or group sessions. Retains heat longer, supports multiple pulls, and integrates with larger glass pieces.

Both sizes use the same quartz heater design and deliver equally incredible vapor.

By heating the cap with a butane torch, the device quickly builds enough thermal mass to vaporize dry herb efficiently. With the right technique, you can go low-temp for delicate flavor or high-temp for dense clouds. Many users find it provides the intensity of combustion-style hits while keeping the purity of vapor.

The Quartz Cap and its paired glass bowl create an all-glass vapor path, ensuring nothing interferes with flavor. There are no metals or electronics involved. Every piece is handmade for quality and durability, with two optional stainless steel screens included if you prefer easier cleanup when using ground herb.

The cap requires only a butane torch (not included). The Quartz Cap is heated until it reaches optimal temperature, then airflow pulls heat down into the bowl for thorough extraction. Its hybrid conduction and convection system balances radiant heat from the cap with hot airflow for consistent vapor production.

Designed exclusively for use with water pipes or J-hooks, the Quartz Cap takes advantage of water filtration to cool and smooth the vapor. Both 14mm and 18mm versions fit standard joints, making them highly compatible with most glass setups.
