The 8591 product is a gland packing made by braiding MacFoil (expanded graphite) yarn reinforced with high-strength carbon fiber into a cross-sectionally square shape. 
Because it uses yarn made of high strength carbon fiber, shaft abrasion is small, and in addition to pressure resistance, heat resistance, sealing performance, excellent performance is demonstrated even under high circumferential speed conditions.
