304 Stainless Steel Braided PTFE Hose for High-Pressure Industrial Systems

Introduction

A 304 stainless steel braided PTFE hose is designed for industrial systems that require chemical resistance, pressure performance and reliable operation across a wide temperature range.

The hose consists of a smooth PTFE inner tube covered by one layer of high-strength 304 stainless steel wire braid. The PTFE inner tube provides resistance to corrosive fluids and temperature changes, while the stainless steel reinforcement improves working pressure, burst strength and mechanical protection.

Shenzhen Jingcheng High-tech manufactures customized single-layer braided PTFE hose assemblies for machinery, automotive production, medical equipment, aerospace systems, chemical processing, energy equipment and other technical industries.

What Is a Single-Layer Braided PTFE Hose?

A single-layer PTFE braided hose combines two primary structures:

• A smooth PTFE material-contact inner tube

• One layer of high-strength 304 stainless steel braid

The smooth PTFE inner surface supports stable fluid flow and helps reduce material retention. The external stainless steel braid limits tube expansion under pressure and protects the PTFE tube against mechanical damage.

This structure offers a practical balance between flexibility, chemical resistance, pressure capability and overall hose weight.

Why Use Stainless Steel Braided PTFE Hose?

Ordinary rubber or plastic hoses may deteriorate when exposed to aggressive chemicals, high temperatures or continuous pressure.

Depending on the medium and working conditions, conventional hoses may experience:

• Swelling

• Cracking

• Chemical degradation

• Permeation

• Pressure expansion

• Premature aging

• Internal contamination

• Reduced service life

A stainless steel braided PTFE hose provides stronger chemical stability and a broader operating temperature range.

Key Features
