Flexible Metal Hose 101: When and Why to Use It
In fluid and gas systems, reliability and adaptability are everything. When standard rigid tubing just won’t cut it—whether due to vibration, thermal expansion, or space constraints—flexible metal hose becomes a critical component. At Tylok Fittings & Valves, we understand the role flexibility plays in ensuring safe, efficient, and long-lasting performance. This blog post breaks down the basics of flexible metal hose, when to use it, and why it may be the best solution for your next project.
🔍 What Is Flexible Metal Hose?
Flexible metal hose is a corrugated stainless-steel tube designed to handle the transmission of gases or liquids under pressure while providing flexibility and vibration resistance. It’s often reinforced with a braided stainless-steel exteriorthat adds strength, pressure rating, and abrasion protection.
Core features:
Material: Typically 316L stainless steel for superior corrosion resistance
Design: Corrugated interior for flexibility; braided exterior for strength
Sizes: Commonly ranges from 1/4” to 2” depending on the application
Connections: Welded ends, threaded ends, or compression fittings
🛠️ When to Use Flexible Metal Hose
Not every fluid system needs a flexible hose—but when it does, using the right one can make all the difference. Here are some ideal use cases:
1. Vibration Dampening
In environments where pumps, compressors, or other equipment cause vibration, rigid tubing can fatigue and crack over time. Flexible metal hose absorbs and isolates that vibration, protecting connected components and extending system life.
2. Thermal Expansion or Contraction
Metal expands and contracts with temperature changes. In systems exposed to wide temperature swings, flexible hose accommodates movement and prevents stress on fittings, valves, or welds.
3. Tight or Confined Spaces
Flexible hose allows installers to route around corners, obstacles, or compact layouts that would be impossible with straight tubing. This is especially valuable in OEM equipment, power generation, or HVAC systems where space is limited.
4. Misalignment Compensation
Sometimes piping doesn’t line up perfectly. Flexible metal hose bridges gaps or offsets in alignment without requiring system redesign.
5. Media That Requires Clean Transfer
In food & beverage, chemical, or pharmaceutical settings, the smooth interior and corrosion resistance of stainless steel are ideal for maintaining product purity and avoiding contamination.

⚠️ Key Considerations Before Installation
When selecting or installing flexible metal hose, consider the following:
Working Pressure: Ensure the hose meets or exceeds system pressure
Temperature Ratings: Match the hose material to your application range
Bend Radius: Follow minimum bend radius guidelines to avoid kinking
Length and Movement: Allow slack for movement due to thermal or mechanical forces
Connection Types: Match end fittings to your system needs (threaded, welded, compression, etc.)
