What Is an Air Hose?
An air hose is a flexible tube that delivers compressed air from a compressor to pneumatic tools. It is designed to withstand pressure, resist abrasion, and ensure consistent airflow in industrial and commercial applications.
What Is Air Hose Made Of?
An air hose is typically constructed in three layers:
Inner tube: Carries compressed air (rubber, PVC, or PTFE)
Reinforcement layer: Provides strength (textile, braided wire, or spiral wire)
Outer cover: Protects against abrasion, weather, and chemicals

How to Choose the Right Air Hose: A Practical Selection Guide
Answer these five questions before purchasing:
1. What PSI should my air hose be?
Calculate your compressor’s maximum output pressure. Add 20% for pressure spikes. Select an air hose rated at least 4x that number. Example: 150 psi compressor → choose air hose rated 600+ psi.
2. What temperature will the hose experience?
Standard rubber: -40°C to +100°C
Polyurethane: -20°C to +70°C (more flexible in cold)
PTFE: -70°C to +260°C (extreme conditions)
3. What fittings and connections are required?
Common options include crimped fittings (permanent, leak-free), reusable fittings (field repairable), adapters (NPT, BSP, JIC, ORFS), and flanges (SAE 3000/6000). For harsh environments, add protective sleeves and spiral guards.
4. How long does an air hose last under your conditions?
Rubber hose: 5–10 years
Wire Braided Hose under impulse: 200,000+ cycles
Wire Spiral Hose under high impulse: 400,000+ cycles
Factors that reduce life: UV exposure, ozone, dragging on abrasives, exceeding bend radius, over-pressurization.
5. Do you need a pre-assembled hose assembly?
A completed hose assembly with factory-crimped fittings eliminates leak points and ensures proper clamp force. Many suppliers offer full hose assembly services including crimped fittings, reusable fittings, adapters, flanges, protective sleeves, and guards.
Common Air Hose Mistakes to Avoid
Using a hose with insufficient pressure rating for the application
Exceeding minimum bend radius, which causes wire fatigue
Twisting the hose during installation, reducing reinforcement life by up to 50%
Dragging hose on abrasive surfaces without protective sleeves or guards
Mixing incompatible fittings from different manufacturers
Ignoring ozone or UV damage on rubber covers

FAQ: Frequently Asked Questions About Air Hose
What PSI should an air hose be?
Select an air hose with working pressure at least 4x your compressor’s maximum output. For a 150 PSI compressor, choose a 600+ PSI rated hose. For systems with pressure spikes, use 5:1 safety factor.
What is the difference between braided and spiral hose?
Wire Braided Hose uses woven steel wires at opposing angles – flexible, medium pressure (300–3,000 psi). Wire Spiral Hose uses spiraled layers – stiffer, higher pressure (3,000–6,000 psi), longer impulse life.
How long does an air hose last?
Rubber air hose typically lasts 5–10 years. Wire Braided Hose under impulse: 200,000+ cycles. Wire Spiral Hose: 400,000+ cycles. UV, ozone, abrasion, and over-bending reduce lifespan.
Can I repair a damaged air hose?
For hose assemblies with reusable fittings, yes – replace only the hose section. For crimped fittings, replacement is recommended. Do not patch high-pressure lines.
What size air hose do I need for an impact wrench?
A 3/8″ ID air hose delivers 15–25 CFM at 100 PSI – sufficient for most 1/2″ impact wrenches. For continuous heavy use or 3/4″+ tools, use 1/2″ ID.
Do I need protective sleeves or guards?
Yes if the air hose drags on concrete, passes through metal openings, or operates near moving machinery. Protective sleeves and spiral guards extend hose life 3–5x.
What fittings are compatible with air hose?
Standard options include crimped fittings (permanent), reusable fittings (field attachable), adapters (NPT, BSP, JIC, ORFS), and flanges (SAE 3000/6000). Request a pdf fittings compatibility chart from your supplier.
Are air hoses MSHA approved?
Select Wire Spiral Hose models carry MSHA certification for underground mining. Specify MSHA requirement when requesting a quote from your manufacturer.
Where can I find an air hose supplier or manufacturer?
Search for “air hose manufacturer China”, “air hose supplier wholesale”, or “industrial air hose factory”. Direct sourcing from a China-based producer typically offers the best bulk pricing and OEM ODM flexibility.
An air hose is a flexible conduit used to deliver compressed air efficiently and safely. Key selection factors include pressure rating, hose size (ID), material type, temperature resistance, and fittings compatibility.
