- Description
-
A 19mm bore is the workhorse size on coach and city bus air conditioning circuits — large enough to carry the refrigerant volume a roof-mounted unit moves, small enough to still bend through a tight engine bay. This A19 hose holds that balance with a 105mm minimum bend radius, the tightest in the bus range.
The 4-layer construction carries a 4.5mm wall with a maximum wall thickness difference of 0.5mm, so the bore stays concentric through bends and clamped sections. Working pressure is rated 3.5 MPa with a 15.0 MPa minimum burst.

On a 6-metre roof run that is roughly 2.6 kg of hose hanging above the ceiling panel, which is why the clamping interval and hanger specification matter as much as the hose itself.
Supplied in continuous lengths or cut to your drawing. Each batch ships with its pressure test record.
