Standard die forming of Graphite Rings the life out of the ring – that’s why we pre-form. We put compressibility and resilience into each ring and that’s what makes the difference.When you receive a pre-formed ring from Smart-Shield, it still has 15% to 20% compressibility left in it.As you install the ring, it’s only necessary to tighten the packing until a seal is effected, which leaves considerable life in the ring for future adjustments. The extra care we take makes the difference. It complements braided packing with inherent lubrication and heat dissipation to enhance operational life at affordable prices, making it a popular sealing device among OEMs and End Users.
