8mm Herb Chamber

This 8 mm herb chamber is CNC machined and made of non-magnetic stainless steel (grade 304). It can be connected to any 8 mm female stem, allowing you to get the most out of your 420eng CouchLog vaporizer. Its high versatility makes it easy to integrate into various setups, while ensuring simple, reliable, and efficient use.

Chris from 420eng, the creator of CouchLog, has fully validated and approved this 👍

👉 It retains the same outer diameter (13 mm) and original length (17 mm, excluding the male interface), as well as all its features, ensuring excellent compatibility with the original stems. Furthermore, it offers two screen positions, allowing you to use your CouchLog with smaller loads while maintaining optimal performance.

The internal diameter is also maintained (10 mm) for the first upper position of the screen. For the second lower position, it is slightly reduced (9.5 mm) to create a shoulder that ensures the screen remains securely in place when used in the first position. A second shoulder is present for the second position, along with a 45° chamfer to ensure optimal flow.

With this one, you can use any screen (preferably 60 to 80 mesh) and standard O-ring.

In addition, it can also be combined with the 8 mm female to 9 mm male adapter, allowing extended compatibility with 9 mm stems (Battery-Free Ganz, etc.) as well as with Tinymight stems (or other stems with an inner diameter of 12 mm).

📦 The supplied 8 mm herb chamber includes:

• 2 × red silicone O-rings¹ (ID 6 mm, OD 8 mm, CS 1 mm)
• 2 × 304 stainless steel screens (⌀ 10 mm, fine mesh)
• 1 × 304 stainless steel screen (⌀ 10 mm, coarse mesh)

In summary, a herb chamber² combining versatility and adaptability.
