Valve Guardian 600/3 Valve Last is a synthetic valve lubricant and sealant with graphite for extreme temperature application. Valve Guardian 600/3 Valve Last exhibits excellent resistance to washout from hot oils, hydrocarbons, asphalts, and solvents. Corrosion inhibitors and extreme pressure additives in Valve Guardian 600/3 Valve Last provide
extended life and compatibility under harsh conditions.Valve Guardian 600/3 Valve Last prevents galling and seizing and provides a tighter seal. It will not melt, drip, or separate.
Valve Guardian 600/3 Valve Last is recommended for plug, gate, ball, and high pressure valves, valves in extreme temperature service, and valves servicing hot oils or asphalts, solvents, and hydrocarbons.
Valve Guardian 600/3 Valve Last is used in the following industries: hot oil companies, solvent manufacturers/processors, gathering systems, utilities, cracking and reforming plants, chemical processors, ref ineries, valve manufacturers, and valve rebuilders.
