Technical FAQ: 8mm Vacuum Hose, Ducting Hose — Expert Guidance

Q1: What is the standard material for high-performance 8mm vacuum hose?

A: Standard options include EPDM (Ethylene Propylene Diene Monomer) and stainless steel (SUS304/316L). Silicone and fluororubber are chosen for chemical applications. All variants comply with RoHS and ISO 9001 standards.

Q2: How does the wall thickness impact vacuum hose performance?

A: Thicker walls (1.5-3mm) enhance pressure capacity and abrasion life but slightly reduce flexibility. For 8mm vacuum hose, 1.8mm-2mm offers a balance—verified for 9 bar under ISO 8031 cyclic pressure testing.

Q3: What installation standards should I follow?

A: Installation should adhere to manufacturer guides plus industry best practices (ANSI/ASHRAE 62.1). Ensure minimum bending radii (e.g., 24mm for 8mm ID), secure ends with proper clamps or seals, and avoid excessive torsion.

Q4: Which certifications are important for vacuum hose in food or clean applications?

A: Look for FDA 21 CFR 177.2600, ISO 9001, CE, and, for high-purity, USP Class VI or EN 16643 certification. Request batch QC and migration test reports from the supplier.

Q5: How are flexible duct hoses tested for leak-proof quality?

A: Hoses undergo hydrostatic and pneumatic pressure tests up to 1.5x rated pressure, vacuum hold for 30 min, thermal cycling, and (if steel) X-ray weld inspection. All results per ISO 8031 or IEC 61386.

Q6: What is the typical lead time and warranty?

A: Standard models (such as 8mm vacuum hose) ship in 2-5 working days. Customized products, depending on length and end fittings, 1-3 weeks. Warranty: 1-2 years standard—Kebing offers up to 3-5 years for select models.

Q7: Can these hoses be used for aggressive chemicals?

A: Yes, with appropriate lining (fluoropolymers, Teflon, or food-grade silicone) and jacket selection. Always specify the medium's temperature/concentration during quotation for tailored recommendations.
