Z-50™ - Oilfield

Tool Joint Compound



Z-50 is manufactured with JETLUBE’s unique grease compounded from custom refined, low sulfur oil. All contain special additives to reduce the plating and buildup of metallic zinc encountered with other zinc compounds.


The grease base ensures brushability over a wide temperature range, tenacious adherence to all surfaces, resistance to water wash out, and the prevention of rust/ corrosion. The metallic zinc particles and other additives are maintained in uniform suspension throughout the compounds, and Z-40, Z-50, and Z-60 displace moisture and adhere well to wet tool joint surfaces.



Designed to provide the maximum protection for tool joint threads and shoulders over a wide variety of conditions. Prevents galling and wear plus ensures consistent rig floor makeup.


Not recommended for oxygen service.
