R10-R2W2-J2.5K is a one-piece weatherproof in-line splice from TE Connectivity. It is designed to connect two wires (R2) with a maximum diameter of 2.5 mm (J2.5K) in a single pass and provide a reliable, moisture-resistant seal. The shell, designed for secure termination, is manufactured from tough polyamide for exceptional temperature and mechanical shock resistance. It also features a Nylon 6/6 housing with a low creep under constant force and high impact strength. The seal within the shell is a specially formulated silicone, providing superior dielectric performance, chemical resistance, and superior seal integrity.
