MOLYKOTE® 1102 Grease
MOLYKOTE® 1102, also known as Gas Cock Grease, is a mineral-oil-based lubricant fortified with inorganic thickener and solid lubricants (notably molybdenum disulfide). It's engineered to lubricate and seal small components such as gas-stop cocks, taps, and valves made of metal, glass, or plastic, providing smooth operation without melting or runoff.
