    OmniSeal® RACO™

    The OmniSeal Raco 1100A Face Seal employs a heavy duty, high load RACO spring with continuous contact along the entire sealing lip. This rugged seal is recommended for extreme static sealing conditions such as those involving cryogenic fluids, ultra high vacuum and positive sealing of light gases. View RACO


    OmniSeal® Fluoroloy® Jacket Materials

    OmniSeal® products utilize Saint-Gobain Performance Plastics’ Fluoroloy® trademarked materials for its seal jacket. Fluoroloy compounds are proprietary blends of premium PTFE resins and fillers, processed for optimum performance. They provide chemically-resistant, low-friction, longer wear life, high and low temperature capability to meet the most demanding applications.
