Marine Exhaust Hose - 1 3/4” (45mm) - 20m Length
Choose this 1 3/4” (45mm) hose for marine wet-exhaust connections. Product 387092 is supplied as 20m Length, so match both the connection size and the supplied quantity to the planned run.
The lightweight corrugated construction provides flexibility for a wet-exhaust route. A black synthetic cover with blue stripe resists ozone, oil and flame, while high-tensile textile cords and embedded steel helix wires reinforce the hose.
The NBR-blend tube handles 40% aromatics. The stated temperature range is -20°C to 121°C, with a 5 bar working pressure and 3:1 safety factor. These are specific limits to compare with the intended exhaust system.
The hose carries Lloyds approval reference 08/1006 (E2). It is designed for wet exhaust fumes; select it according to that duty and the engine exhaust arrangement.
The corrugated outer form and steel-helix reinforcement are practical details when planning a flexible run. Check the route without assuming an unstated minimum bend radius, and leave access to inspect the clamped connections.
Compare the measured connection diameter at both ends with this size before ordering. The full 20 m length is the fixed supply format for this code; allow for the actual number and length of runs being planned.
Measure the required route before choosing the quantity, allowing for the connections at each end. Use the hose’s stated application and limits as well as its diameter when matching it to the system.
The 5 bar working-pressure limit is distinct from the stated 3:1 safety factor. Use the working limit for selection; the safety factor is not an alternative operating-pressure rating.
