TEMPIL 28045 TEMPILSTIK is a calibration‑free, wax-based temperature-indicator stick designed to melt precisely at 288 °C (550 °F). It delivers instant visual confirmation when threshold temperature is reached, making it ideal for welding preheat, interpass, post‑weld heat treatment, and industrial process control. Each stick is permanently imprinted with part number and lot code for traceability, complies with AWS, ASME, and ANSI/ASME thermal codes, and is manufactured in the USA. Trusted in fabrication, shipbuilding, oil & gas, railroad, and metalworking industries.
