The RPG 5-Gal Bead Seater, from Ascot Supply, is designed for heavy duty, commercial use to quickly inflate large truck tires, passenger and ATV tires up to 24.5" in size. The bead seater is equipped with a butterfly valve for maximum air discharge, and also features rubber foot pads to lessen vibration while in use. The long reach metal barrel also has a specially designed lip that delivers a quick air blast between tire and rim at the perfect angle and position to ensure that the job gets done, the company says. The bead seater comes with an easy-to-read gauge to ensure the recommended operating pressure (psi) is used.
