Frequently Asked Questions (FAQ)
What is the maximum pressure rating for this tubing?
Pressure rating depends on the inner diameter, wall thickness, and temperature. As a general guide, our standard black silicone rubber tubing is suitable for low to medium-pressure applications (typically up to 5-6 bar for smaller diameters). Please consult our technical datasheets or contact our team for specific pressure ratings based on your requirements.
Is it suitable for potable water applications?
Yes. We offer specific grades of our black silicone rubber tubing that are compliant with FDA CFR 177.2600 and other international food contact regulations, making them safe for use with potable water and food products. Please specify this requirement when inquiring.
Can the tubing be sterilized?
Absolutely. Silicone rubber is highly resistant to heat, steam, and chemical sterilants. Our tubing can be repeatedly autoclaved (steam sterilized), treated with ETO (ethylene oxide), or irradiated without significant loss of properties, making it ideal for medical, laboratory, and food processing uses.
Do you offer custom lengths and packaging?
Yes. We provide standard coils and cut lengths. For OEM partners, we can supply on reels, in custom-cut lengths with end caps, or in bulk packaging tailored to your assembly line needs. Minimum order quantities apply for custom packaging.
What is the lead time for sample requests and bulk orders?
Free samples of standard items are typically dispatched within 2-3 working days. For bulk production orders, standard lead time is 15-30 days after order confirmation, depending on quantity and specifications. We maintain strategic stock of popular sizes for faster turnaround.
