Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for precision-engineered plastic components. Since 2017, we have been serving global markets including North America, Europe, and Southeast Asia with a 1,000-3,000 sqm factory and a dedicated team of 51-100 employees. Our Tier 1 Supply Chain Transparent Graduated Tube is specifically designed to meet the rigorous demands of automotive and industrial applications. Combining high transparency with exceptional dimensional stability, this tube offers reliable fluid level indication and long-term performance in high-temperature environments.
This graduated tube is manufactured from a special PC SAN (Polycarbonate/SAN) blend that provides excellent clarity, impact resistance, and anti-creep properties. It complies with IATF16949 standards (based on our TS16969 quality system), ensuring consistent quality for Tier 1 automotive supply chains. The tube is ideal for use as oil level gauges, coolant sight glasses, or fuel system components where both visibility and thermal resistance are critical.
Product Features and Technical Specifications
- High Transparency: Crystal-clear visual for easy liquid level reading, with minimal distortion.
- Anti-Creep Performance: Special PC SAN formulation reduces cold flow under continuous stress, maintaining dimensional accuracy over time.
- High Temperature Resistance: Suitable for continuous operation up to 130°C, with short-term peaks to 150°C.
- Graduated Markings: Precision-engraved or printed scale lines (mm, cm, or custom units) for accurate measurement.
- Chemical Resistance: Resists oils, coolants, and mild chemicals commonly found in automotive systems.
- IATF16949 Compliance: Manufactured under strict quality control processes aligned with automotive industry standards.
- Customizable Dimensions: Available in a wide range of outer diameters (6mm to 50mm) and lengths (50mm to 1000mm). Wall thickness can be adjusted to meet pressure requirements.
- Surface Finish: Smooth internal and external surfaces to prevent fluid adhesion and ease cleaning.

Why choose our graduated tube for your Tier 1 supply chain? The combination of anti-creep performance and high temperature stability ensures that the tube retains its shape and scale accuracy even after thousands of thermal cycles. This significantly reduces maintenance costs and improves system reliability. Additionally, the transparent nature allows quick visual inspection without disassembly, saving downtime.
Our manufacturing facility in Changzhou, Jiangsu (with supply chain options from Thailand as per product title) employs advanced injection molding and extrusion technologies. We have been exporting to over 15 countries and regions, including North America, Europe, and Asia. Every tube undergoes rigorous dimensional inspection and pressure testing to meet the tightest tolerances (±0.1mm on diameter, ±0.5mm on length).

Frequently Asked Questions (FAQ)
-
Q: What is the maximum working temperature for this tube?
A: The PC SAN material can continuously operate up to 130°C, with intermittent peaks up to 150°C. For applications requiring higher temperatures, we can recommend alternative materials. -
Q: Are the graduation marks permanent?
A: Yes, the markings are either laser-engraved or printed with high-durability ink that resists solvent and abrasion. They will not fade under normal use. -
Q: Can I get custom lengths and diameters?
A: Absolutely. We offer customizable dimensions, including outer diameter from 6mm to 50mm, lengths from 50mm to 1000mm, and wall thickness as per your requirements. Minimum order quantities may apply for non-standard sizes. -
Q: Is this tube suitable for fuel or oil exposure?
A: PC SAN has good resistance to aliphatic hydrocarbons, motor oils, and coolants. However, prolonged exposure to concentrated acids, bases, or solvents should be avoided. Please consult our technical team for specific chemical compatibility. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 2-3 weeks. Custom orders typically require 4-6 weeks, depending on complexity and quantity. We can expedite for urgent projects with prior arrangement. -
Q: Does the tube have a shelf life?
A: When stored in a cool, dry place away from direct UV light, the tube can be kept for at least 5 years without significant degradation. -
Q: How is the anti-creep property verified?
A: We perform creep testing per ASTM D2990 at elevated temperatures (e.g., 100°C under 5 MPa stress for 1000 hours). The strain remains below 1% in our qualified materials. -
Q: Do you supply samples for evaluation?
A: Yes, we can provide free samples (shipping cost may apply) for customers who intend to place orders. Please contact our sales team with your requirements.
At Changzhou Hongxinyutai Precision Mold Co., Ltd., we are committed to delivering excellence. Our transparent graduated tube combines precision, durability, and compliance with automotive standards – a reliable choice for your Tier 1 supply chain.
