A nylon line joining the crankcase of the engine to the oil separator. It carries the fuel vapour, oil mist and a share of exhaust contained in blow-by gas to the separator, where the separated oil drains back while the fuel vapour returns to the intake tract to be burned.

The tube is formed from a heat- and oil-resistant nylon so as to live with engine-bay temperature, oil mist and continuous vibration.

Tube material: extruded nylon PA12, optional PA66 reinforcement layer; dimensions: inner diameter Ø8/Ø10/Ø12/Ø16 mm, wall thickness 1.5-2.5 mm; media: fuel vapour, oil mist and blow-by gas mixture; temperature range: -40 °C to 150 °C, short peaks to 160 °C; pressure rating: 0.05-0.3 MPa working, ≥1.2 MPa burst; connection type: SAE/VDA standard quick connectors, ≥500 mating cycles; bending: minimum bend radius 30 mm at Ø12 mm bore; endurance: fuel vapour permeation ≤0.5 g/m² per 24 h, ozone and salt-spray resistance ≥480 h
