When does a hose actually need a fluorocarbon (FKM) lining?

2026-10-16

When the inside of the hose sees oil or fuel vapour rather than only air or coolant. Standard silicone is a poor host for hydrocarbons: oil mist migrates into the wall over time, the rubber swells and softens, and the hose can delaminate from the inside out — a failure that a visual inspection from the outside will not catch.

A fluorocarbon-lined hose puts an oil-resistant layer against the medium while the outer wall stays silicone, so the flexibility and heat range are kept without the swelling. On a turbo engine the usual candidates are crankcase breather hoses, turbo oil feed and drain areas, and any charge pipe downstream of a PCV outlet. Fupower builds fluorocarbon-lined silicone hose for exactly these positions.
