Thermal degradation: High temperatures sometimes cause grease color to lose its vibrance. A heavily pigmented grease will become more pastel and less vivid with exposure to high heat. Grease color can denote performance in specific applications. For instance, the moly component of gray grease allows it to function in severe conditions. Again, the color itself is usually not relevant to performance, but color-coding might indicate. Several factors can impact grease’s performance, including the: Castrol is a brand of red rubber grease that is specially formulated for the lubrication of natural rubber components. It is used to lubricate rubber products in cars and commercial vehicles. You’ll find it in parts like clutch hydraulic mechanisms and brakes. Is Red Rubber Grease Compatible with Brake Fluid? A premium quality multi-purpose extreme pressure lithium complex grease for lubricating all anti-friction and plain bearings. Used in industrial and automotive applications. It has shown exceptional performance providing extended lubrication intervals over wide operating temperatures. Yes, red rubber grease is waterproof. That’s why it is able to protect rubber components from water ingress. However, water resistance is in levels. Some brands of red rubber grease provide higher levels of water resistance than others. So, it is a good practice to find out the level of water resistance a particular brand of grease provides before paying for it. One brand of red rubber grease that offers a high level of water resistance is Castrol red rubber grease. 5 Major Benefits of Red Rubber Grease:

Also, I use the X-Tra Heavy Duty Grease on the fittings of all my vehicles regularly. This is the only grease I've ever used that actually does what it says it will do. Other greases have not lasted nearly as long or as well. It is compatible with all kinds of natural and synthetic rubber components. That’s why it is used to lubricate O-rings, bushings, and seals. In addition, it is also compatible with brake fluids.Since it is resistant to water, it will protect natural and synthetic rubber components from water ingress. A good example of how well the Oil Stabilizer works is when I ran it in my EQUALIZER motor that had NO oil pressure. I used 70% Oil Stabilizer and 30% regular motor oil. The motor held up for a full night of racing and still looked great when I tore it down later. Besides grease darkening due to operating and environmental conditions, a shift in color could be a sign that the grease has mixed with a different type of grease unintentionally. If this occurs, immediate action should be taken to determine how and why this has happened. Careless greasing with the wrong grease is more common than most people realize, and the effects of grease mixing are very bad for machine reliability and grease performance. Resist leakage: Grease can also help to prevent leakage. As a sealant, grease keeps desired materials in and undesired materials out.

Red Rubber Grease is specifically designed for the lubrication and protection of rubber components and should only be used for this purpose. In other words, RRG can be used for lubrication where there is rubber and there is no gasoline: o-rings, non-petroleum oil and dust seals, dust boots, bushings. This means that whenever you’re looking to buy grease to lubricate rubber components, you should be looking for red grease. Also, if you’re trying to buy grease to lubricate metal components and you come across red grease, shun it. Red grease is meant for rubber components. Red grease is compatible with synthetic and natural rubber products. What is Castrol Red Rubber Grease? Reducing friction and tear: Grease allows you to extend equipment life spans by lowering friction and cutting down on wear and tear. Ungreased parts rubbing against each other can lead to mechanical failure. If you want your machinery to operate at peak performance with extended life spans, you will have to apply the right type of grease and do so regularly. Learn what various grease colors mean and which you should choose for your application. What is Grease?No such thing as "best" grease- just volumes of individual opinions. Any grease that meets the requirements of your specific application is "best" While color does not impact lubricating abilities, manufacturers may use color-coding to denote lubrication. Grease is designed to hold lubricants in place, and the lubricants contained in the mixture will determine how it functions. Look for the type of oil a grease contains —mineral oil or synthetic fluid — to learn about its lubricating capabilities. Does Grease Color Impact Performance? To differentiate rubber grease from other types of grease in the production line, manufacturers added a red dye to the grease during its manufacturing process. This red dye gives rubber grease its red color. So, whenever you come across any red grease, it’s probably rubber grease.

milky may indicate water contamination. Additionally, if different greases are mixed in service, the resulting color may be a mix of the two. The table below shows how a particular grease color may refer to several different types of grease, especially among lithium-complex greases. Also, some brands, like Castrol red rubber grease, last longer than other brands. So, you should choose a trusted brand. Even if it’s slightly more expensive, it will last longer. That being said, red rubber grease generally lasts for about three to five years. Is Red Grease Waterproof? Red rubber grease is fully biodegradable. It will decompose naturally on its own. That’s why it has a shelf life.As grease degrades and becomes contaminated, it usually will begin to darken. This darkening, which can be more noticeable when compared to new grease, may be a sign that the grease has reached a condemning limit. Although it should not be surprising that grease darkens, the rate at which it darkens is the important factor.
