The 2590S Threaded Hanger is designed for lower pressure wells and handles coiled tubing sizes up to 1.75.. Like the 2590R, the primary seal is enacted as the string weight compresses the packing element through the slip cone. The lock-down cap provides additional compression force on the slips and packing element for a secure pressure seal against the coiled tubing. The steel alloy retaining ring securely retains the packing element in the body. It can be removed easily to facilitate field replacement of the packing element.
