Designed to withstand heavy-duty use, Snap-On’s 18-volt cordless grease gun, model CGG4850, has a 7,500-psi hose that operates at minus-5 degrees Fahrenheit, according to the company.

If a grease gun is rated to 10,000 psi, beware when replacing the hose. Replacement hoses from auto parts stores are often rated to only 5,000 psi. Some battery-powered grease guns offers two speeds.
