21132674 Bellows Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta anti-barnacle bellows kit for the steering cylinders, weighing 0.17 kg and listed for 24 applications. The accessories catalogue prints it under the DPH and DPR drives, in the same block as drive joint bellows kit 3594509, exhaust bellows kit 3588753 and seawater intake hose kit 3588767 - and it is the one item in that block the DPI listing does not carry. The bellows shields the exposed steering cylinder rod and its seals from marine growth, abrasive contamination and corrosion.

🚤 Compatibility

• Engine Family: DPH, D, TSK, DPR
• HP Range: 150-480 HP
