Air Gap Spacers & Cushion Pipes
‘Air gap’ or ‘twin wall’ pipes are often used for the manufacture of downpipes. Insulation is provided by the air gap between inner and outer pipes, reducing heat loss from the exhaust gas prior to the catalytic converter. This results in improved light-off times.
DemisterASIA wire mesh spacer rings and cushion pipes are situated between the inner and outer pipe. This acts as a bearing surface, maintaining a constant gap through changes in thermal expansion whilst absorbing and reducing vibration.
All of these are from the same reliable maker of DemisterASIA demister based in UK.
