FIRE FIGHTER No. 40 is a flame and heat resistant embroidery thread which is important to industries such as the Fire service, Motorsports and gas, oil or chemical companies where protective clothing is paramount. 

Fire Fighter No.40 is made of 100% fire-resistant Aramid fibres containing DuPonts® Nomex® and complies with STANDARD 100 by OEKO-TEX®. The thread is designed to resist ignition and prevent flames from spreading, as well as to self-extinguish once the source of the fire is removed.

24 colours on 950m mini snap cones. 

For best sewing results we recommend the use of needle size #75/11-80/12.
