Import Air Rubber Hose — Buy in Bulk from Supplier in China

Laizhou Kiynn Rubber & Plastics Products Co., Ltd. supplies air rubber hoses from Laizhou Industrial Park in Shandong Province, China, engineered for compressed air and water transfer in industrial settings. The hoses feature a tube and cover constructed from synthetic rubber compounds, reinforced with textile braids to withstand working pressures typical of pneumatic service. Available bore sizes range from compact 6mm ID up to larger 50mm ID configurations, with wall thicknesses calibrated to balance flexibility against kink resistance. The supplier specifies abrasion and weather resistance as standard properties, ensuring service life in exposed workshop and construction environments. Colour coding, typically red or black, aids line identification during installation. The lightweight construction referenced in the source material reduces fatigue during manual handling and repositioning.

The inner tube compound is typically formulated from NR/SBR blended rubber for resilience under cyclic pressure, while the cover incorporates EPDM or similar synthetic rubber to resist ozone cracking and UV degradation. Reinforcement layers of high-tensile synthetic textile yarn, applied at controlled braid angles, contain the radial expansion under pressure. Working pressure ratings for general-purpose air hoses of this construction typically fall between 10 bar (150 psi) and 20 bar (300 psi), with burst pressures at minimum 3:1 safety factor. Temperature service range is standard at -20°C to +80°C for the tube compound, though confirm exact compound formulation with the supplier. End fittings are not pre-attached on bulk hose orders, allowing buyers to select BSP, NPT, or quick-connect couplings matched to their existing pneumatic infrastructure.

Primary buyers include equipment rental firms, automotive repair workshops, mining operations, and general manufacturing facilities running compressed air tool circuits. The hoses serve pneumatic chipping hammers, paint spray systems, tyre inflation rigs, and general workshop air drops. Agricultural irrigation and dewatering applications also represent typical use cases where water compatibility is specified. For importers, confirm whether Laizhou Kiynn offers cut-length bulk coils or pre-assembled hose kits, as this affects landed cost calculations and inventory planning. The supplier has not disclosed specific MOQ, lead time, or Incoterms in the listing, so direct negotiation is required to establish commercial terms.

Laizhou Kiynn Rubber & Plastics Products Co., Ltd. operates from Laizhou Industrial Park in Shandong Province, China, a region with established rubber processing and polymer manufacturing infrastructure. The supplier is classified as an imported-tier account with harbour trust classification, indicating basic profile verification without advanced audit or inspection disclosure. The response rate shown is 0.00% with zero average response hours recorded, suggesting the profile may be passively maintained or that response metrics are not yet populated. No employee count, annual revenue, year of establishment, or factory certification details appear in the source material.

The listing positions the company as a manufacturer of rubber and plastic products with air rubber hoses as an advertised line. No specific production capacity, in-house testing capability, or quality management system accreditation is stated. Buyers should verify directly whether Laizhou Kiynn holds ISO 9001 or equivalent quality system certification, and whether production is in-house or subcontracted within the Laizhou rubber goods cluster. The absence of trade assurance data or verified shipment records in the source means importer due diligence, including sample evaluation and factory verification, is advisable before committing to volume orders.
