Technical Advantages
✔ True Circular Cross-Section
Every tube maintains a perfectly round cross-section, ensuring tight fitting and leak-free connection.
✔ High Precision Dimensional Control
Advanced online extrusion monitoring guarantees ±0.05–0.15mm tolerance, improving fitting compatibility and reducing installation failure.
✔ Winter Flexibility Stability
Unlike lower-grade TPU tubes that harden in cold environments, MAHOP® SL/SLM remains flexible under normal winter conditions (-20℃).
✔ No Surface Wax Migration
The material formulation prevents surface blooming, keeping tubes clean and stable during long-term use.
✔ Small Bending Radius
Designed for compact installations and confined automation layouts.
Common problems with SL/SLM hoses
Tube Hardening in Winter
✅ 96 Shore A formulation ensures stable flexibility in low-temperature environments.
Leakage Due to Oval Shape
✅ Strict extrusion control guarantees true round cross-sections.
Installation Difficulty
✅ Small bend radius design allows easy routing in compact spaces.

FAQ:
What is the difference between SL and SLM series polyurethane tubes?
The SL series is made from high-grade polyester TPU, offering excellent abrasion resistance and oil resistance.
The SLM series uses polyether TPU, which provides improved hydrolysis resistance and better stability in humid environments.
What is the working pressure of MAHOP® polyurethane pneumatic tubes?
The standard working pressure is 8 kgf/cm² (approximately 0.8 MPa) under normal operating temperature conditions (-20℃ to 60℃).
Are your polyurethane tubes perfectly round?
Yes.
All MAHOP® tubes are produced using precision-controlled extrusion systems to ensure a true circular cross-section.
This improves fitting compatibility and reduces air leakage risk.
Do you provide OEM or private label service?
Yes.
We support:
- Logo printing on tubes
- Private label packaging
- Custom box design
- Special extrusion requirements
We regularly supply OEM customers in Southeast Asia, Middle East and Europe.
