Why global water dispenser OEMs choose Yutian

🧴

True food grade · Zero taste transfer

FDA & LFGB certified · BPA / Phthalate‑free

Platinum‑cured, no peroxide byproducts. Certified to FDA 21 CFR 177.2600 and LFGB migration standards. 100% BPA and phthalate‑free, ensuring pure water taste even after prolonged hot water contact. Every batch undergoes 200°C × 4h post‑curing to eliminate VOCs and low‑molecular cyclic siloxanes.

→ Meets global drinking water safety standards

🌡️

Hydrolysis resistant · Extreme temperature tolerance

-40°C to +200°C · handles boiling & ice water

Silicone’s Si‑O‑Si backbone resists hot water hydrolysis. Remains flexible at -40°C and stable at +200°C – no softening, no deformation. Specifically engineered for “instant heat” and “chilled water” dual systems. Tensile strength retention ≥85% at 100°C after 168h immersion.

→ Reliable for both heating and cooling circuits

💪

Pressure rated · 3× safety margin

Working ≥0.9MPa (9 bar) · Burst ≥2.7MPa

Uniform wall thickness (tolerance ±0.1mm) ensures high burst strength. 3‑5× safety factor prevents hose detachment or bursting from water hammer in frequent pump cycling. 100,000‑cycle pulse fatigue test available on request.

→ Prevents costly water damage claims

🧼

Smooth inner bore · Anti‑biofilm & anti‑scale

Ra ≤ 0.4μm · bacterial adhesion reduced by 92%

Mirror‑finish extrusion tooling delivers an ultra‑smooth inner surface that resists biofilm formation and scale buildup. Per JIS Z 2801, our hydrophobic surface reduces bacterial adhesion by 92% compared to standard rubber tubes – keeping water paths hygienic and extending filter life.

→ Hygienic drinking water · less maintenance

📏

Precision dimensions · secure fit on any barb

ID tolerance ±0.1mm (or ±0.05mm on request)

Tight control on inner diameter and wall thickness ensures leak‑free connections with quick‑connect fittings and barbs. For non‑standard barbs, we can fine‑tune the die within 3 days. Flared ends and chamfering available for faster assembly.

→ Consistent quality · easy installation

⚙️

Fully customisable – ID, wall, length, colour, marking

ID 2‑15mm · wall 1.0‑5.0mm · any length

Custom inner diameter, wall thickness, hardness (40‑80A), and colour (Pantone matched). Support laser marking, colour co‑extrusion stripes for circuit identification, and cut‑to‑length with tight tolerances. ODM/OEM projects welcome.

→ Perfect for OEM projects

Frequently asked questions

Q1: Will this tube develop a “plastic smell” after long‑term hot water contact?

A: Absolutely not. We use platinum curing instead of peroxide curing. Platinum leaves zero VOC residues or acetophenone. Each batch undergoes post‑curing (200°C × 4h) to ensure ultimate purity – odor‑free for life. Even after 168h immersion in 95°C water (GB 4806.11), zero taste or turbidity.

Q2: How do you ensure a tight seal on barb fittings to prevent leakage under water hammer?

A: We control ID tolerance to ±0.1mm (or ±0.05mm on request), far exceeding industry standards. This ensures the perfect “grip force” on quick‑connect or barb fittings – tight enough to prevent leaks, but not too tight to hinder assembly. We provide a 100,000‑cycle water hammer pulse fatigue test report to guarantee zero leakage over the appliance’s 5‑year lifespan.

Q3: Does the tube soften or leach harmful substances at 95°C+ hot water?

A: Silicone’s Si‑O‑Si backbone provides inherent heat resistance. Our continuous working temperature is 200°C. At 100°C, tensile strength retention ≥85% – no thermal creep. It passes FDA and LFGB overall migration tests. Absolutely no BPA, BPS, or heavy metal leaching, even at high temperatures.

Q4: How smooth is the inner bore? Does it prevent biofilm?

A: Using mirror‑finish extrusion tooling, inner surface roughness reaches Ra ≤ 0.4μm (vs. PVC ~1.6μm). Per JIS Z 2801, our hydrophobic surface reduces bacterial adhesion by 92% compared to standard rubber tubes, significantly delaying biofilm formation and keeping the water path hygienic.

Q5: Is the tube flexible enough for tight bends? Will it kink and stop flow?

A: Our compound uses high‑vinyl silicone for superior low‑temperature flexibility. Brittleness temperature ≤ -60°C. For tight bends (R=15mm), we offer thicker walls or braided reinforcement options, ensuring inner diameter collapse<10% – no kinking, no flow interruption.

Q6: Can the tubing withstand ozone, UV‑C, and autoclave sterilisation?

A: Yes. Tested at 50pphm ozone for 200h – no cracks. UV‑C (254nm) for 500h – no chalking, hardness change<3A. Resists 121°C autoclave steam cycles. PVC ages within days under ozone/UV – silicone is clearly superior.

Q7: Do you have NSF certification? What’s the difference vs. FDA?

A: We hold FDA 21 CFR 177.2600 and LFGB. FDA is federally mandated and legally enforceable in the US; NSF is voluntary. Our material fully complies with NSF 51 ingredient requirements. If needed, we can co‑sample for NSF 51 testing and assist with documentation (we already have 80% of baseline data).

Q8: Is the material 100% pure silicone? Any cheap fillers like calcium carbonate?

A: We own the compounding factory, giving us full recipe control. We never add cheap fillers beyond standard reinforcement. You can verify via TGA – our ash content is stable at ≤35% (pure silicone theory), far lower than adulterated products (>50%). We contractually guarantee material purity.

Q9: What if my barb fitting is non‑standard (e.g., 7.5mm ID)?

A: Send us your barb drawing or sample. Our tooling team will fine‑tune the die for free and deliver matched custom sizes within 3 days. We also offer flared ends or chamfering for faster assembly.

Q10: I need a small trial run (e.g., 100m). Will prices change or delivery be delayed for bulk?

A: Our promises are contractual: Quotes valid for 1 year (unless raw silicone fluctuates beyond ±15%). 1% daily penalty for our delayed delivery (industry average 0.1‑0.3%). We accept trial orders as low as 100 meters/size, and sample costs are fully refundable against bulk orders.

Q11: Why are your prices higher than some small workshops?

A: The price gap reflects hidden differences: (1) We use virgin gum equivalent to Dow Corning / Shin‑Etsu quality – not recycled oils. (2) Platinum catalyst (5‑8x cost) eliminates acetophenone residues. (3) Every batch undergoes 5 mandatory QC tests (hardness, tensile, tear, TGA, FDA migration). Our quality prevents costly overseas recalls – making us the most cost‑effective in the long run.

Q12: Can you add my logo or colour stripes to differentiate water lines?

A: Absolutely. Two options: (1) Colour co‑extrusion – 1‑3 stripes (e.g., Blue=Cold, Red=Hot) for circuit identification. (2) Laser marking – permanently engrave LOGO, part numbers, or batch codes on the surface – alcohol‑resistant, food‑contact safe, and tamper‑proof.

What our customers say

“We switched to Yutian silicone tubing for our hot water dispenser line. The material has zero taste transfer – our customers no longer complain about plastic smell. The dimensional accuracy is excellent, and the tube remains flexible even after 5000+ hot water cycles.”

— Senior Engineer, Home Appliance Brand

“Yutian’s FDA‑certified tubing solved our leakage issues in the field. The ±0.1mm ID tolerance gives us confidence in assembly. Their fast sample turnaround and contractual delivery penalties made them our preferred partner.”
