The 19.2-Volt Rechargeable Grease Gun is a powerful tool for any place of work or business, generating up to 8,500 psi of operating pressure.  The battery recharges in only one hour and lasts long enough to dispense up to three tubes of grease.  It's ideal for hard-to-reach fittings (30-inch flexible hose with spring guard), and it relieves worker fatigue and speeds up routine maintenance.
