Rubber Hose Selection Guide: How to Choose the Right Hose

Choosing the right rubber hose starts with four questions: 1. **What media will flow through it?** (hydraulic oil, water, air, fuel, chemicals, steam, food) 2. **What pressure will it operate at?** (working pressure + safety factor of 4:1 for burst) 3. **What size do you need?** (inner diameter, matched to flow rate and velocity) 4. **What environment will it serve?** (temperature, abrasion, ozone, UV, chemical exposure) ## Standards to know - **SAE 100R1 / R2** — wire braid hydraulic hose - **EN 853 1SN / 2SN** — European equivalent of SAE 100R1AT / R2AT - **EN 856 4SP / 4SH** — four-wire spiral for very high pressure - **ISO 2398** — rubber air hose - **ISO 1403** — rubber water hose - **EN 559** — welding hose - **EN 1360** — fuel dispenser hose ## MOQ and wholesale pricing For B2B buyers, ordering in 100 m+ rolls unlocks wholesale pricing.
