The TFER-3/4-X-STK is a heat shrink tubing product manufactured by TE Connectivity. Heat shrink tubing is used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. The '3/4' likely refers to the diameter of the tubing before shrinking, and 'X' may denote a specific material or color. 'STK' could refer to the standard stock part.
