Ordinary pneumatic hose often stiffens and cracks with heat, UV exposure, or contact with oil mist and mild chemicals. Pressure spikes cause ballooning or blowouts, and repeated bending leads to fatigue kinks. This Corrosion-resistant and Aging-resistant Pneumatic Tubes uses a specially formulated polymer with integrated UV stabilizers and anti-aging additives. The result is a corrosion resistant air hose that stays flexible, keeps its pressure rating, and doesn’t develop surface crazing or through-wall leaks after years of industrial use. For operations that need consistent air delivery without creeping maintenance costs, this aging resistant pneumatic tubing is a direct, factory-backed replacement option with custom diameters, colors, and cut lengths available.
Hengshui Zhehan has focused on durable pneumatic tube manufacturing for years, and this product reflects that experience. The one-step extrusion process yields consistent wall thickness and a dense, uniform structure, so working pressures up to 1.6 MPa are maintained safely with a burst pressure of 4.8 MPa. Because the inner bore is extremely smooth, flow resistance stays low—air delivery efficiency improves by about 15% compared with rough-bore commodity tubing. The material also resists oil mist, moisture, salt spray, and mild chemical fumes, delivering more than 85% improvement in corrosion tolerance over standard PU/PVC pneumatic tubes under the same conditions. Instead of constantly swapping out hardened or swollen tubing, teams can keep equipment running.
Installed on robot arms, assembly lines, and pneumatic grippers where the tube must tolerate rapid pressure cycles and continuous flexing without kinking or fatigue splitting.
Handles areas with weak acid or alkali mist, cutting oils, and high humidity that would otherwise cause conventional tubes to corrode, embrittle, or perforate. Suitable for valve actuation and control air lines.
Used on outdoor machinery and farm implements, with strong resistance to UV radiation, rain, dust, and wide temperature swings. The tube retains flexibility in the cold and doesn’t harden in the sun.
Feeds clean, stable air to welding positioners, plasma cutters, and spray systems. The smooth interior prevents flow restriction, while oil and spatter resistance keeps the line intact and accurate.
The modified TPU formulation withstands oil, weak acids and alkalis, moisture, and salt fog. Even in continuously damp or fume-laden environments, the tube surface won’t blister, peel, or develop leaks—keeping this corrosion resistant pneumatic tube reliable over extended campaigns.
Integrated UV inhibitors and anti-oxidant additives help the material resist hardening, cracking, and discoloration. In outdoor testing with alternating sun, rain, and temperature shifts, the tubing continues to perform for over three years without losing its original flexibility.
A uniform, extruded wall and tight molecular structure give a standard working pressure rating of 1.6 MPa with a burst pressure of 4.8 MPa—well above many commodity pneumatic hoses. That margin helps prevent sudden blowouts and pressure loss under fluctuating loads.
The Corrosion-resistant and Aging-resistant Pneumatic Tubes has a small bend radius and excellent recovery memory. It can be flexed through 180° repeatedly without flattening or cracking, making it straightforward to route around machinery frames, moving joints, and panel connections.
The mirror-like inner surface minimizes friction and turbulence. Steady, low-loss air delivery keeps pneumatic tools and actuators operating at consistent speed and torque, which is especially valuable in precision assembly and spraying.

Before pressurizing, check for cuts, kinks, or abrasion. Do not exceed rated pressure or temperature limits. Avoid sharp edges, heavy crushing loads, and forced small-radius bends that could pinch or damage the wall.
Keep the tube exterior free of built-up dust, oil sludge, and chemical puddles. After equipment shutdown, relieve line pressure to reduce long-term stress on the material and extend service life.
Where possible, position tubing away from direct intense UV and continuous high-heat sources. For extreme corrosive conditions beyond mild chemical exposure, contact us to discuss a custom compound; we can adjust the material to match the environment.
Use compatible push-in or compression fittings and ensure a full, tight seal. Route lines clear of hot surfaces, moving parts, and areas subject to mechanical abrasion to minimize wear.
Q: What’s the minimum order quantity?
A: Standard sizes ship from just one roll. We carry popular diameters in stock, so small trials and urgent replacements are no problem, and we offer scaled pricing for volume orders.
Q: Can you supply custom lengths, colors, or branded tubing?
A: Yes. We provide full OEM options: custom inner diameter, wall thickness, coil length, color, and logo printing. Our team can also adjust pressure ratings and temperature specifications if your equipment demands something outside the standard range.
Q: How does this TPU tube differ from ordinary PU or PVC pneumatic hose?
A: The main difference is longevity under real industrial conditions. The modified TPU compound resists oil, hydrolysis, UV, and flex fatigue far better. While a standard tube might stiffen or crack within a year, this aging resistant pneumatic tube is built to stay pliable and leak-free for years in outdoor and corrosive atmospheres.
Q: Is the tubing suitable for lubricated compressed air?
A: Yes. The material has good oil resistance, so light oil mist carried in compressed air won’t degrade the inner wall. It’s a solid choice for systems using air tool oilers.
Q: What quality guarantees do you provide?
A: Every reel is covered by a 12-month warranty against manufacturing and material defects under normal use. Products are batch-tested for pressure and dimensional stability, and we can supply test reports on request. Defective tubing is replaced free of charge.
Q: Can I get cut pieces instead of full rolls?
A: Absolutely. We offer cut-to-length service, so you only pay for what you actually need, whether it’s a few meters for a prototype or hundreds of meters for a production line.
Q: How soon can orders ship?
A: In-stock sizes typically ship within 1–3 working days. Custom configurations take a little longer, and we’ll confirm the exact lead time when you send your requirements.
