ThredOn™ Enviro-1

Yellow Rated Thread Compound

ThredOn™ Enviro-1 is a technologically advanced, extremely water resistant, biodegradable base grease formulated with natural mineral fillers and other environmentally friendly additives. It contains no metals or PTFE. It can adhere to wet joints over a wide temperature range and protects threads for superior makeup and breakout performance. It has the added convenience of being light in color to assure consistent coverage.

Recommended Uses

Enviro-1 is used for tool joints, tubing and casing, as well as legs of jack-up rigs. It can be used for storage and thread protection, slides and any highly loaded, slow moving surface.

Enviro-1 meets requirements for the most sensitive marine environments, including Norway Yellow Y1, Cefas E, and VGP EAL for US waters (US EPA).
