Choosing the right rubber hose material directly determines service life, safety and cost efficiency. For global industrial buyers, selecting EPDM, NBR, Silicone (VMQ) or FKM (Fluoroelastomer) based on real working conditions is the core of reliable piping solutions.

EPDM (Ethylene Propylene Diene Monomer) EPDM is the top choice for water, steam, cooling systems and outdoor use. It excels in weather, ozone, heat and aging resistance, with a working temperature of -50℃ to +150℃. It is widely used in HVAC, automotive cooling lines, air hoses and water delivery. Not suitable for oil environments.

NBR (Nitrile Butadiene Rubber) NBR is the most cost-effective oil-resistant material. It performs well against fuel, lubricants and hydraulic oil, with a temperature range of -40℃ to +120℃. Ideal for engine oil hoses, fuel lines, hydraulic circuits and petroleum applications. Poor in outdoor weather resistance.

Silicone Rubber (VMQ) Silicone stands out for extreme temperature stability and food safety. It works smoothly from -60℃ to +230℃, features non-toxic, odorless and hygienic properties. Widely used in food machinery, medical lines, high- temperature air ducts and automotive silicone hoses. Lower oil and tear resistance.

FKM (Fluoroelastomer) FKM is the premium grade for harsh harsh environments: high temperature, strong corrosion, oil and chemicals. It withstands -20℃ to +200℃ (short-term up to 300℃). Perfect for automotive engine compartments, chemical conveying, high-pressure hydraulic systems and heavy industry. Higher cost but longest lifespan.

Quick Selection Summary

· Water / outdoor / HVAC → EPDM
