AMMEX GlovePlus Black Nitrile is a premium industrial grade nitrile glove; that is 50% thicker than standard nitrile gloves with three times the puncture resistance versus latex or vinyl gloves. As a result, these black nitrile gloves are durable and last longer, so fewer glove changes are required. GlovePlus Black Nitrile gloves feature superior chemical resistance against common chemicals, like carburetor cleaner, and many other specialty chemicals, such as iodine and butane, that you may encounter on the job. The glove holds up to brake fluid and, even after being dipped in gasoline, stays true to form.
