This is the inner tube for all 8-4.00 and 8-4.00/4.80 wheelbarrow tyres. It is universally applicable so just check the tyre size. Some of the low priced wheelbarrows use an 8-3.00 tyre, and this is not the tube for that smaller size.

It is produced using butyl rubber which is much more impermeable to air than the lower priced natural rubber tubes that lose considerable air pressure over 12 months.
