The KINK3D Airlock® is one of our original creations! It's a 3D-printed lock adaptor, which can be used in place of the standard lock when you need a 100% metal-free setup. The plastic seal with a unique number can also be used to prove how long you've been locked. Each Airlock comes with 10 numbered plastic seals included. If you need additional seals, they can be purchased here. The Airlock is recommended for use only with KINK3D Cobra and Viper chastity cages. The Airlock is not designed for use with KINK3D Shaft Rings, as the numbered seal would rest directly on the skin. How to use the Airlock The short video at the end of this product gallery shows the standard method for putting on the Airlock. However, putting on the Airlock is notoriously tricky! An easier method involves putting it on backwards (shown in our FAQ). Note: The new base rings available through KINK3D On Demand are designed with a notch in the lock chamber, which makes it much easier to use the Airlock.
