MOLYSLIP PVG-679 AND PVG-679WG are fully synthetic greases that have been specifically formulated for the lubrication of gate and plug valves operating in the petrochemical industry. The combination of synthetic base fluid, solid lubricants, corrosion inhibitors and stabilisers ensure that PVG-679 and PVG-679WG have maximum resistance to chemicals encountered in the exploration and production of crude oil and gas. They act as lubricants to the valve components and will assist in maintaining or regaining sealing performance to minimise leakage.
