AI-Powered supplier vetting

SummaryThe supplier is a limited company with 98 employees and a product range covering pneumatic, brass, plastic and related fittings, PU hose and speed controllers. It reports ISO9001 experience and lists ISO9001:2015, ISO45001:2018 and ISO14001 certifications, plus RoHS capability. Quality assurance and supplier-service assessment procedures are documented, while complaint handling has a procedure but no written records. The supplier offers broad customization and ODM services, reports new products within the past year, maintains R&D documentation and 47 patents. Production-related strengths include in-stock capability, stated lead times within 15 working days in both seasons, and a plant exceeding 10,000 square meters. Limitations include no OEM service for popular brands, no overseas warehouse, showroom, agent or branch, no valid manufacturing contract with related subcontractors, and no available SDK. Financial credibility and customer-case evidence remain insufficient for a conclusive assessment.

Supplier typeThe supplier is identified as a limited company, independent of a larger company group, with 98 employees and a plant area exceeding 10,000 square meters. Its stated product scope includes pneumatic, brass and plastic fittings, PU hose and speed controllers, indicating a specialized industrial-components manufacturer.

CertificationsThe supplier states that it has quality assurance in quality-control processes, previously obtained ISO9001, and lists ISO9001:2015, ISO45001:2018 and ISO14001 certifications, together with RoHS capability. The slices support a positive certification and quality-system assessment, although certificate validity details are not provided.

After-Sales capabilityThe supplier has a corrective and preventive action procedure with followed records and a customer-complaint procedure, but complaint handling has no written records. It also lacks overseas warehouses, showrooms, agents and branches, and reports zero countries with overseas services, limiting its demonstrated international after-sales infrastructure.

R&D capabilityThe supplier reports new products within the past year, provides R&D design input/output, review, verification and validation records, and has 47 patents. These are explicit indicators of active innovation, although no SDK is available and software-instrument capability is confidential.

Production capacityProduction evidence includes a plant exceeding 10,000 square meters, in-stock capability, stated average lead times within 15 working days in both peak and off-season, and documented supplier-service assessment procedures. A material risk remains because the factory and related subcontractors do not have a valid manufacturing contract.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization and flexible customization, together with ODM services. R&D personnel are responsible for product improvement and production support, and supporting design documentation is available for audit, demonstrating broad customization capability.

Product Q&A

Q:What are common causes of air leakage in this fitting?

Common causes include gaps in threaded connections, poor sealing ring contact, uneven tube cross-sections, damaged sealing rings, excessive air pressure, unclean gas, or aging of the sealing ring due to moisture.

Q:How should I install the tube to prevent leakage?

Ensure the tube cross-section is cut flat to allow proper contact with the sealing ring. Insert the tube firmly into the joint until it clicks into place.

Q:What maintenance is recommended for the sealing ring?

The sealing ring may age over time, especially with moisture in compressed air. Regularly inspect for aging or damage and replace if necessary to prevent air leakage.

Q:Can I use this fitting for hydraulic systems?

Yes, it is suitable for oil and fluid lines requiring secure bulkhead mounting in hydraulic equipment and lubrication systems, provided the media is non-corrosive.

Q:What is the connection method for this fitting?

It uses a push-to-connect method on both tube ends with a one-touch release ring for easy tube removal and installation.
