Made from custom-conductive rubber tubing, these rings are smooth, flexible, and easily adjustable to fit any girth with the integrated cord locks. The tube's inner diameter is designed to accommodate standard 2mm electrode pins, ensuring seamless compatibility with the COYOTE Power Box and other accessories. Conductive rubber typically has relatively high resistance, which can result in a weak sense of stimulation during use. To solve this problem, Dungeon Lab developed a custom low-resistance rubber substrate and integrated it with a conductive silver core. This reduces the resistance from several hundred ohms to just a few dozen ohms. This third generation of rubber rings introduces a new 6 mm diameter style. Compared with the 4 mm version, it offers a larger contact area with the human body for a more comfortable feel, though the elasticity is slightly reduced. Different styles of rubber rings each have their own distinct tactile characteristics. Choose according to your personal preference. When used together with a conductive lubricant, the pulse sensation can be further enhanced. With the Dungeon Lab 4 mm Mesh Conductive Rings, the conductive rubber tube is externally braided with conductive silver fibres. This requires careful cleaning after use. The woven wires have a relatively short lifespan, making them suitable for professional use.
