🔹Tip ① – Before each bottle change, check the condition of the gasket: correct placement, wear, or hardening. If any deviation is detected, immediately replace the gasket using protective gloves. When connecting, ensure the threads are correctly aligned to avoid cross-threading, which can compromise the seal. 🔹Tip ② – If there is a leak at the central connection, first replace the gasket as shown in the illustration. Then, submerge the adapter in water to check for bubbling. If necessary, improve the seal by wrapping Teflon tape around the threads. 🔹Delivery Kit – 1 × CO₂ cylinder adapter (TR21-4 internal thread, W21.8 external thread). 2 × washers (one already assembled, the other as a spare). 2 × orange O-rings for the central threaded rod. 1 x Allen key. 🔹Usage – Made of high-quality aluminum alloy, robust, corrosion-resistant, and ideal for food applications.
