Sealey 12V Heavy Duty Compressor

Big Sealey pump offers a lot for the money.

Unlike most of its rivals here, it can be run for long periods, and it’s pretty effective, too, pumping 8psi into our test tyre in a minute.

Storage works well, even though there’s a huge four-metre lead. Not so good is the analogue gauge – it crams car relevant pressures into a few millimetres, and was around 5psi shy in our test.
