To stop cross-contamination, the answer is clear. Cross-contamination is the cause of 60 to 80% of bearing failures. The way to prevent this is clear: UltraView clear grease guns. When the wrong product is used to lubricate machinery, it can get expensive, as damaged machinery may need to be replaced - and at considerable cost! Now you can eliminate the possibility of using the wrong grease with an innovative grease gun featuring a shatterproof, high-tech polycarbonate, see-through barrel. You can also save on product purchasing costs, as you won't need a separate grease gun for every oil/grease product you're using. Just get separate clear canisters for each product and you're ready to go. Some of the great benefits to these guns include: ability to identify which type of grease is in the gun; equipment can be color coded to grease gun; prevents using incorrect grease in equipment; eliminates cross-contamination and costly mishaps; determine amount of grease remaining in a bulk-loaded gun.
