STAINLESS STEEL DUPLEX SWAGE SLEEVES ESCO stainless steel duplex sleeves provide the quickest, simplest way to make strong swaged turnback eyes in wire rope. Duplex sleeves permit easy adjustment of eye size. Grommets, plain eyes and tight thumbed eyes can be made quickly and precisely every time without splicing or die changes. Among the most rugged swage sleeves ESCO makes, these stainless steel swage sleeves are cast with the popular 40SS stainless steel, which was created specifically for swaging. High initial ductility allows ESCO stainless steel to flow evenly around the wire rope during swaging, for total gripping strength and extremely high crack and fracture resistance. During swaging, ESCO stainless steel work-hardens more than any other swaging steel to provide toughness, on-the-job durability and corrosion resistance. Ductility for even flow and high crack resistance, work hardening for resistance to abuse, and corrosion resistance make ESCO stainless steel swage sleeves the reliable, durable industry choice.
