The Polyvinyl insulated extension grade thermocouple wire, J, K and E wire types are rated from 0 to 105°C (32 to 221°F) for the insulation. The range type T extension wire is rated from -60° to 100°C (-76 to 212°F). The PFA insulated extension grade J, K, and E are rated up to 260°C (500°F). The Type T extension wire is rated to 200°C (392°F). Used for a wide variety of applications, these cables are our standard construction PVC or PFA wire with a metal overbraid of tinned copper or stainless steel, and an overall outer jacket of PVC or PFA. This construction add durability and assures long term abrasion resistance. **Note:** Published prices are based on market value at time of printing and are subject to change due to Nickel surcharges, Chromium and precious-metal market fluctuations. |**Copper Overbraid**
