Rubber industrial hoses are flexible, industrial-grade hoses designed for tasks like transferring air, water, oil, or food products. Common types include air rubber hoses, water rubber hoses, oil rubber hoses, and food-grade rubber hoses. In our last guide, we covered how to choose an industrial rubber hose pipe. Today, we’ll break down another key factor: the type of inner tube wall—since this directly impacts flow, flexibility, and performance.
1. Smooth Inner Wall: Ideal for High Flow & Precise Control in Rubber Hoses
A smooth bore rubber hose has an inner wall that’s completely smooth, with no wrinkles or ridges. First, this smooth surface lets media (like air, water, or oil) flow freely—no barriers to slow it down. As a result, smooth bore rubber hoses deliver very high fluid transfer capacity. If you need precise flow control (e.g., in chemical processing or food production), a smooth bore design is better. Its even inner wall won’t disrupt flow with irregularities.
Smooth inner walls also make drainage easier. After use, media won’t get trapped in crevices—critical for food-grade rubber hoses (to avoid contamination) or oil rubber hoses (to prevent residue buildup).
Note: Almost all rubber industrial hoses (except metal hoses) can have a smooth inner wall—making it a versatile choice for most applications.
2. Ripple Inner Wall: Boost Flexibility for Tight Spaces
A ripple wall rubber hose (also called a corrugated inner wall hose) has a tube wall folded in a specific pattern.
This folded design is built to improve bending ability. So, ripple wall rubber hoses offer excellent flexibility—perfect for tight spaces where a stiff hose can’t reach.
