Max-Tuff is an ultra-tough, synthetic lubricant designed for use in reassembling repaired equipment.

Max-Tuff utilizes durable synthetic molecules that adhere to metal surfaces and create an extremely strong barrier between surfaces. This minimizes the possibility of metal-to-metal contact while providing excellent protection against rust and corrosion to both ferrous and nonferrous metals.

Max-Tuff is formulated with Royal Purple’s proprietary Synslide® additive technology.


Maxfilm is a multipurpose, synthetic lubricant that excels in many applications. It deeply penetrates, cleans and loosens rusted parts.

Maxfilm leaves an exceptionally tough and durable lubricating film for improved operation and long-lasting protection against wear, rust and corrosion.
It’s recommended for:

Loosening stuck parts such as nuts, bolts, locks, hinges, etc.
Lubricating power tools, hinges, chains, rollers, open gears, fishing tackle, lawn equipment and more.
Preserving and protecting parts in storage against rust and corrosion.
Acting as a manual cutting fluid for easier hand drilling, tapping, metal cutting, etc., of both steel and aluminum.


MaxSolv is a very powerful chemical solvent which rapidly removes oxidized oil deposits such as sludge, varnish and lacquer that are commonly formed in a wide range of equipment. Maintenance personnel can replace dangerous acid and caustic cleaners, eliminate labor-intensive mechanical cleaning and let the equipment clean itself of deposits while using MaxSolv during normal operation.

MaxSolv is formulated to be added to the existing oil just prior to draining the oil and refilling the equipment with new oil. MaxSolv works by softening and then displacing or dissolving oxidize oil deposits. Deposits will be removed when draining the old oil. Any remaining sediment being easily flushed or wiped clean.

Carefully read the MaxSolv product sheet before use as MaxSolv also removes metal coatings such as paint, etc.


NGL-NS™ is a premium, synthetic lubricant specifically designed to increase the service life of reciprocating gas compressors in hydrocarbon service where sulfur-sensitive catalysts are present downstream of the compressor. NGL-NS™ is virtually sulfur free and is formulated with dense, closely packed, synthetic molecules to greatly resist dilution from compressed hydrocarbon gases. It is also extremely hydrophobic and rapidly separates from water, which protects bearings and other components from rust and corrosion. TECH TIP NGL-NS™ makes gas compressors run longer with minimum wear

Open Gear Guard XP

Open Gear Guard XP is designed to effectively lubricate open gears and chains subjected to heavy loads in dusty or dirty environments. It is a unique, thixotrophic lubricant blended with a solvent carrier that is easily applied by either spraying or brushing. Once applied, the carrier film evaporates leaving a tenacious, dry, wax-like film that minimizes the collection of abrasive dust and other airborne contaminants.

Open Gear Guard XP has excellent EP properties due to its formulation with Royal Purple’s proprietary Synslide®additive technology and can effectively lubricate at temperatures up to 400° F. The solid lubricating film left after the solvent carrier evaporates consists of Calcium Carbonate and Calcium Sulfate, both of which are naturally occurring minerals.

Caution — Consult manufacturer for high temperature applications
