ROYCO® 634 Cleaner, Lubricant & Preservative

Royco 634 Cleaner, Lubricant and Preservative combines 3 essential functions in 1 convenient product. Royco 634 MIL-PRF-63460D can be used to maintain a variety of large and small caliber handheld weapons, to maintain automotive engines, airplane engines, marine engines and for general plant maintenance of industrial equipment. It works in virtually all climate conditions from -65 °F to +150°F and contains no ozone depleting compounds to meet California Clean Air Act VOC requirements. Only a thin layer of Royco 634 is required for complete, long-lasting protection.

ROYCO 634 Applications
ROYCO 634 is formulated to meet the complete requirements of cleaning, lubricating, and preserving both small and large calibre weapons in virtually all climate conditions from -65 °F to +150°F. In addition, ROYCO 634 contains no ozone depleting compounds and meets California Clean Air Act VOC requirements.

ROYCO 634 is not limited only to ordnance use; in fact, it has been proven effective in a wide variety of applications including automotive, aviation, marine, and general plant maintenance of industrial equipment.

ROYCO 634 provides additives that in addition to their ability to penetrate between metal surfaces, aid in the effective removal of built up dirt, corrosion particles and firing residues that can be abrasive to both recoil and gas operated mechanisms.

After cleaning, a thin-film layer of preservative forms immediately on the surface that not only displaces water but provides a corrosion resistant barrier against rust and dirt.

ROYCO 634 incorporates advanced technology additives to enhance film strength and antiwear properties - thereby reducing friction between moving parts and minimizing wear and the build-up of wear-related debris. ROYCO 634 is not limited only to ordnance use; in fact, it has been proven effective in a wide variety of applications including automotive, aviation, marine, and general plant maintenance of industrial equipment.
