Twin Balanced Piston Dry Kit For 15X Mares 416813

Description:

The Mares Twin Balanced Piston (TBP) Dry Kit is an add-on accessory designed to convert Mares 15X first stages into fully insulated, cold-water capable units. Its core function is to prevent first-stage freezing and maintain consistent breathing performance when diving in temperatures below 10°C and at extreme depths. The TBP combines Mares’ Pistophragm technology with a fully insulated construction to deliver exceptional responsiveness to pressure variations and reliable function in demanding environments. Built to be easy to assemble and service, the kit is suitable for field repairs and integration into existing 15X regulator setups. Durable and engineered for harsh conditions, it is ideal for contaminated-water operations, under-ice exploration, and technical deep dives where thermal protection and reliability are critical. The system meets NORSOK U-101 requirements at depths up to 200 m, giving professional and advanced recreational divers confidence in performance.
