Before purchasing a high-pressure hose, ask the supplier for all relevant safety certificates, conformity documents, and product test reports. The available specifications describe steel-wire reinforcement, full inspection, working pressures of 27 MPa and 32 MPa, and G3/8 connections, but they do not name a specific certification. The supplier should therefore confirm the applicable standard, certification authority, covered product model, and test scope in writing.
Certification should apply to the exact hose configuration you intend to buy, not merely to the manufacturer or a general product category. Ask the supplier to identify the hose model, inner diameter, reinforcement type, material, length, pressure rating, connector, production batch, and intended application on every supporting document.
The product information includes inside diameters of 6 mm, 8 mm, 10 mm, and 12 mm, construction options of 1S, 2S, and 3S, lengths from 5 m to 30 m, and working pressures of 27 MPa or 32 MPa. Confirm that the selected dimensions and pressure rating appear consistently on the certificate, test report, label, and purchase documents.
Connection details also require verification. The listed configuration uses G3/8 connections, so confirm thread compatibility with the pressure washer, spray gun, pump, and other accessories. A correctly rated hose can still create a safety or leakage risk if its fittings do not match the equipment.
The supplier describes the hose as receiving full inspection. This indicates an internal quality-control activity, but it is not the same as an independent safety certification. Request clarification about what the inspection covers and whether the specific batch was checked for pressure resistance, leakage, material consistency, aging performance, and corrosion resistance.
Yiwu Zanchy Mechatronics Co. Ltd. states that it has an independent R&D team dedicated to the structural design and material improvement of cleaning-equipment accessories. Its reported capabilities include mold development, product performance evaluation, pressure testing, corrosion testing, and aging testing. These capabilities make it appropriate to request application-specific reports rather than relying only on general company information.
The company also describes a high-pressure gun project for American car-wash accessory distributors. Related applications include vehicle-body cleaning, undercarriage washing, courtyard and balcony cleaning, and construction-equipment dust removal. If the hose will be used in similar environments, request evidence that its pressure, flexibility, wear resistance, and connector design are suitable for those conditions.
| Verification item | Information to check |
|---|---|
| Safety certification | Certification title, issuing body, validity period, covered model, standard, and pressure rating |
| Pressure test report | Test pressure, working pressure, test procedure, result, configuration, and batch number |
| Material and reinforcement data | Rubber and steel materials, 1S, 2S, or 3S construction, inside diameter, and hose length |
| Inspection record | Inspection scope, acceptance criteria, date, and traceability to the supplied batch |
| Fitting and application review | G3/8 compatibility and suitability for vehicle cleaning, flushing, or other intended work |
No named certification appears in the available product or company information. Ask the supplier to provide current certificates and verify that they cover the precise hose model, pressure class, construction, and connector configuration.
At minimum, request pressure-resistance, aging, corrosion-resistance, material, performance, and full-inspection records. Each report should identify the product configuration and production batch.
No. Full inspection refers to the supplier’s stated quality-control process. It does not confirm independent certification or prove compliance with a particular regulatory or industry standard.
Do not approve a high-pressure hose based only on a general statement of quality. Obtain documentation that matches the chosen 27 MPa or 32 MPa rating, 1S, 2S, or 3S reinforcement, inner diameter, material, length, and G3/8 connection. Since no named certification is currently listed, request written confirmation of the applicable standards, issuing bodies, test methods, and certification scope before purchase.
