1140671 Exhaust Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta rubber exhaust hose for marine wet exhaust systems, in the 63 mm internal diameter size with a 75 mm external diameter and a minimum bend radius of 355 mm, weighing 1.624 kg and listed for the D11C series. The hose conforms to ISO 13363 type 2, rated to plus 580 degrees Celsius, and to SAE J2006 type R2. It is reinforced with synthetic textile layers and an embedded steel wire helix, and has a plain, smooth inner surface for minimum exhaust back pressure and a smooth outer surface, so it resists heat, seawater, vacuum and engine-room vibration. Volvo Penta lists it sold by the metre, with stainless steel hose clip 961674, in this same run, as the recommended clip.

🔌 Function

Forms the flexible section of a wet exhaust run, allowing exhaust gas and cooling water to pass between rigid pipework while absorbing engine movement and mounting tolerances.

⚠️ Common Signs of Failure

• Cracking, splitting or surface crazing of the rubber, especially near the clamped ends
• Softening, swelling or hardening from heat exposure
• Exhaust gas or water leaking at the hose or clamp joints
• Collapse or ballooning of the hose wall under pressure or vacuum
• Loss of shape or kinking, restricting flow through the hose

🛠️ Service Notes

• Never route it tighter than the 355 mm minimum bend radius
• Fit the recommended clip 961674 and renew both clips with the hose
• Recommended stainless steel hose clip for this size is 961674
• Do not bend it tighter than the 355 mm minimum bend radius
