ePTFE Joint Sealant is a high-performance, mono-directional gasket tape made from 100% pure expanded PTFE resin, engineered to deliver unmatched reliability in the most demanding sealing environments. Backed with a pressure-sensitive adhesive for quick and accurate placement, it forms a durable, form-in-place gasket that conforms instantly to virtually any surface—whether it's smooth, rough, pitted, concave, or irregularly shaped. With a temperature tolerance up to 600°F (315°C), pressure resistance up to 3,000 PSI, and universal chemical compatibility across the entire pH 0–14 spectrum, ePTFE Joint Sealant outperforms traditional soft gaskets and eliminates common issues like creep, cold flow, and thermal degradation. It is ideal for flange sealing in chemical processing, food and beverage production, pharmaceuticals, pulp and paper, and power generation systems—especially where cleanliness, compliance, and resistance to aggressive media are critical. Its non-stick surface ensures clean separation from flanges during maintenance, while its low-friction flexibility makes it easy to install, even on large or awkward sealing surfaces. With an unlimited shelf life, ePTFE Joint Sealant is the go-to choice for maintenance professionals, engineers, and OEMs seeking a long-lasting, cost-effective, and universally adaptable sealing solution.
