Specifically formulated to meet the performance requirements of proprietary, metal-to-metal seal, and high interference connection designs utilizing high performance materials including super chrome and high alloy steels. The smaller particle size distribution may not provide optimum seal performance on 8-round and buttress thread forms. SEAL-GUARD ECF has an advance base containing a carefully selected balance of synthetic and vegetable oils with Jet-Lube extreme base grease thickener technology coupled with innovative solid lubricants. The result is superior lubrication under high loads with galling resistance equivalent to heavy metal based compounds in a totally metal-free formulation. This patented technology provides a high affinity to metal surfaces with a low added solids content. Ideal tubing connections - premium.
