Markal 08910 Anti-seize Lubricant 10 Oz Copper Base

Product Description

The MARKAL 08910 is a copper-base, extreme pressure anti-seize lubricant formulated for high-heat and high-load fastening applications. Rated to 1,800 degrees F (982 degrees C), this silver-gray compound prevents galling, seizing, and corrosion on threaded and mating metal surfaces exposed to extreme temperatures and heavy mechanical stress. Packaged in a 10 oz can, it applies easily to fasteners, shafts, valve stems, and splines before assembly. The water-resistant formula holds up in wet or humid service environments. It is not food grade and not nuclear grade. Licensed HVAC technicians, plumbers, pipefitters, and industrial mechanics reach for this compound during routine and preventive maintenance work.

This anti-seize compound is suited for commercial and industrial applications where conventional lubricants fail under heat or pressure. Typical uses include boiler and steam system fasteners, pump and compressor assemblies, valve packing glands, bushings, and splined shaft connections. It is appropriate for both new assembly work and field maintenance where components must be disassembled in the future without damage to threads or mating surfaces.

Key Features

Compatibility

Designed for use on threaded fasteners, valve stems, splined shafts, bushings, and other metal mating surfaces in HVAC, plumbing, and industrial mechanical applications where high heat and extreme pressure conditions are present.

Installation Notes

Apply by a licensed mechanic, pipefitter, or HVAC technician following the system manufacturer's torque and assembly procedures. Shut down and de-energize or depressurize the system before servicing any component. Apply a thin, even coat to clean, dry threads or mating surfaces before assembly. Avoid skin contact and work in a ventilated area; consult the product safety data sheet for handling and disposal guidance.
