The Click-N-Seal Ultra has been introduced to provide a durable and thermally stable fluid connection fitting. The compact, torque-limiting fittings are made from PEEK plastic, the industry standard for durability. PEEK plastic allows the fittings to provide stability even at very high temperatures. The company's technology prevents fittings from over or under-tightening, causing poor fluid connections and leaky processing without tools or guesswork. When the correct torque is reached, the product produces a click that the installer can feel and hear, physically preventing tightening beyond that point. The fitting can be unthreaded and reused.
