Chemola™ ThredOn™ 301 EZE-Break DC

Premium TFE Rotary Shoulder Compound


Chemola™ ThredOn 301™ EZE-Break DC compound is a lead-free high pressure compound for rotary shouldered connections. It is compounded with PTFE and other solid additives to maintain a positive thread seal while preventing galling in the most extreme environments. Special corrosion inhibition and oxidation stabilization additives are present to prevent rust and expand shelf life. It insures a positive seal under pressure and ease of breakout without excessive torque.

Recommended Uses
301 can be used for rotary shouldered connections in high torque operations. It is easy to apply to hot, wet or dry surfaces.
