3860374 Hydraulic Hose | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta hydraulic hose from the Marine Propulsion group, weighing 0.154 kg and listed for 7 applications on TSK installations. It is the heavier by 13 grams of an otherwise identical pair with 3860373 — same name, same group, same fitment — so the figures published do not separate them and the part number is the only reliable guide.
