3-ply Hose Structure
For inner layer of 3-ply PVC air hose, we use high-density PVC to produce.
So the sooth inner tube reduces airflow resistance and improves conveying efficiency.
And the anti-static design reduces dust absorption.
It’s oil-resistant and chemical resistance suitable for a variety of industrial environments.
The middle layer use high strength polyester to reinforcement.
Function:
Provides compressive support to prevent hose expansion or bursting.
Enhanced tensile strength to prevent deformation during use.
Outer Layer: Wear-Resistant PVC
Material: Modified PVC: Contains UV and anti-aging additives
Features:
Abrasion and scratch resistance, suitable for dragging on the floor or mechanical friction environments.
Ozone and UV resistance, durable for outdoor use.

Hose Advantages
Safe and durable: The three-layer construction ensures no deformation or bursting under high pressure, with a lifespan over twice that of ordinary single-layer hoses.
Lightweight and flexible: Weighing only 50% of rubber hose, it’s easy to move and install.
Low flow resistance: The smooth inner wall reduces pressure loss and improves the efficiency of pneumatic tools.
Environmental resistance: The outer layer is UV-resistant and oil-resistant, making it suitable for harsh environments such as factories, construction sites, and mines.
Application Scenarios
Pneumatic tools: nail guns, grinders, paint sprayers, etc.
Industrial automation: pneumatic components for production lines, air supply for robotic arms
Construction sites: concrete spraying, jackhammer connections
Automotive repair: tire inflation, brake system testing
Recommended Specifications
Common inner diameters: 1/4” (6.5mm）3/8” (10mm) 5/8” (16mm)
Custom lengths: Available in 10m to 100m rolls, with an optional anti-tangle coil.
Supporting connectors: 1/4″ NPT, quick couplers
Guarantee of 3-ply PVC Air Hose
Redundant Safety Design
Actual burst pressure reaches 60 bar, far exceeding the nominal 20 bar, providing safer handling of pressure peaks.
Cost Optimization
60% lighter than rubber high-pressure hose, reducing handling and installation costs.
A service life of 3-5 years (twice that of ordinary hose) reduces replacement frequency.
Efficiency Guarantee
Inner diameter accuracy of ±0.2mm ensures stable airflow and prevents tool power loss.
