AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company rather than an offshore company or professional technical supplier. It offers broad customization and ODM services, but reports no 3D software design service, no new products in the past year, no SDK, and no OEM service for popular brands. After-sales support includes debugging, maintenance, repair, training, and equipment installation, with overseas service coverage listed in seven countries, although it has no overseas branches, agents, warehouse, or showroom. Service-control procedures and corrective-action records are documented, while the approved-supplier list lacks approval signatures or dates. ISO9001:2015 and CE-related certification capability are reported. Financial credibility cannot be confirmed because the provided financial indicators are all stated as zero. Production outsourcing procedures, contracts, and in-stock capability are either unknown or unavailable.

CertificationsThe supplier reports an ISO9001:2015 certificate and lists CE among its product certification capabilities. The slices do not provide certificate validity, scope, issuing body, or expiry details.

After-Sales capabilityAfter-sales offerings include debugging, maintenance, repair, training, and equipment installation, supported by listed overseas service countries and participation in Interschutz 2026. However, the supplier has no overseas agents or branches, warehouse, or showroom, so service delivery infrastructure is partly limited.

R&D capabilityThe supplier provides ODM services and multiple forms of customization, but reports no new products in the past year, no SDK, no 3D software design service, and no professional technical R&D capability. This indicates service-based design flexibility but limited demonstrated innovation infrastructure.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, flexible customization, and ODM services. These statements directly support a broad customization offering despite the absence of 3D software design services.

Product Q&A

Q:What materials are used for the SNG10-08 coupling?

The coupling is typically manufactured from high-grade stainless steel (304/316) or carbon steel with anti-corrosion coating. Custom materials (brass, aluminum) are available upon request.

Q:What is the maximum working pressure of this hose valve coupling?

Depending on material and size, the standard working pressure ranges from 150 psi to 300 psi (1.0-2.0 MPa). Please contact us for a detailed pressure rating chart.

Q:What is the difference between SJ Series and DJ Series?

SJ Series uses a standard single-seal design for general fluid transfer. DJ Series features an additional locking or double-seal mechanism for higher safety and leakage prevention under pulsating pressure or vibration.
