Silicone upper radiator coolant hose for Massey Harris Pony 820 TM - Peugeot 203 engine

What is this upper radiator hose?

The REDOX upper radiator hose for the Massey Harris Pony 820 TM is manufactured from high-performance VMQ silicone, reinforced with 3 plies and featuring a 4 mm wall thickness. It connects the Peugeot 203 engine to the top of the water radiator. Hand-wound and oven-vulcanised, this silicone hose far outlasts the original natural rubber hose, which is prone to swelling, cracking and bursting over time.

Applications and compatible models
