Why Choose 95A Polyurethane Pipe for Pneumatic Systems

Understanding What “95A” Really Means in Polyurethane Tubing

When selecting a polyurethane pipe for compressed air systems, “95A” is not just a number on a datasheet—it defines how the tubing behaves in real working conditions. 

The “A” refers to Shore A hardness, a standardized scale used to measure the softness and elasticity of materials such as polyurethane. 

A hardness of 95A means the tubing offers an ideal balance between flexibility and structural strength, sitting between ultra-soft hoses and rigid plastic tubing. 

In applications where pneumatic tubing must tolerate mechanical stress while maintaining ease of routing, this specification becomes a deciding factor.

How Hardness Influences Air Flow Stability and Pressure Resistance

Hardness plays a direct role in how air tubing performs under pressure. Softer tubes may kink or expand under load, while overly rigid tubing is prone to cracking in dynamic environments. 

A 95A polyurethane tubing structure resists internal deformation, allowing stable airflow even under repeated pressure cycles. 

This characteristic makes 95A pipes suitable for automated assembly lines, packaging machinery, and robotic arms where movement and airflow must stay consistent.

Flexibility That Simplifies Installation Without Sacrificing Strength

One of the most common frustrations with plastic tubing is difficult routing in compact equipment. Engineers prefer tubing that bends smoothly without losing its shape.

 A 95A pu tube offers controlled flexibility—easy to insert, route, and connect, yet rigid enough to hold position under vibration. 

Compared with ultra-soft lines, it also resists collapse when vacuum or negative pressure is applied. This directly reduces downtime during installation and servicing.

Abrasion and Chemical Resistance in Industrial Environments

A polyurethane pipe is often exposed to oil mist, lubricants, cleaning agents, and metal fragments. Hardness influences surface durability, 

and 95A offers excellent abrasion resistance. It also shows strong tolerance toward hydraulic oils, diluted acids, and alkalis. 

According to industry material studies from polymer testing laboratories, polyurethane significantly outperforms PA and PVC in durability. 

This translates into longer service life and fewer replacements in demanding factory environments. 

Where 95A Fits Compared to 98A Polyurethane Tubing

FOKCA’s standard pneumatic tubing is manufactured to 98A hardness, giving higher pressure resistance and shape retention. 

However, in applications requiring frequent bending or manual installation, 95A polyurethane is often preferred.
Choosing between the two depends on working conditions:
