Alcor 86159 EGT/TIT SCREW-IN (1/4 NPT) TYPE K REVERSE STAGGER

The **Alcor EGT/TIT Screw-in Style Probe** (P/N **86159**) is a **Type K thermocouple** designed for **exhaust gas temperature (EGT)** and **turbine inlet temperature (TIT)** measurement on reciprocating-powered aircraft. The probe features a **small element diameter** that provides near-instantaneous instrument response and generates sufficient electrical power for **Alcor unamplified instruments**. A **built-in radiator** minimises the high-temperature effects on internal spot-weld connections. It is intended for use with **Type K EGT or TIT instruments and leads**. The **lead wires are configured in reverse stagger (long red and short yellow)**. The probe is accurate to **±25°F at 1500°F**. **Type K** EGT, TIT and some CHT thermocouples are identified by **red (-)** and **yellow (+)** wires. Type K thermocouples are manufactured using **alumel (red)** and **chromel (yellow)** metals. Type K is the industry standard for **EGT** and **TIT**, although some manufacturers specify Type K for use in digital and/or amplified **CHT** indicators. The Alcor EGT/TIT Screw-in Style Probe is **FAA approved** and **PMA approved** for use on **all reciprocating-powered aircraft**, includes **Hardware Kit P/N 38094 (4 ea. washer, nut and screws)**, and is backed by an **industry-leading 5-year warranty**. --- ## Applications The Alcor 86159 EGT/TIT Screw-in Style Probe is intended for: - Reciprocating-powered aircraft - Type K EGT instruments - Type K TIT instruments - Type K EGT and TIT leads --- ## Why CJ Aerospace?
