Packaging Instructions

To ensure the safe delivery of the goods, our hydraulic hose fittings are professionally packaged to balance protection, convenience and cost-effectiveness:
● Bulk packaging: Thick woven bags or cardboard boxes are used, with each fitting placed in its own compartment to prevent damage from collisions.
● Outer packaging: For large orders, wooden pallets are used for reinforcement, suitable for long-distance shipping by sea or air. The labels clearly indicate the product model (model), quantity (quantity) and weight (weight).
● All packaging has dust-proof, moisture-proof and corrosion-proof functions to ensure that the fittings arrive intact.

Quality Control

We strictly follow international and national standards and implement a full-process quality control system to ensure that each joint meets the requirements of industrial applications:

● Raw material inspection: Select high-quality carbon steel, stainless steel, etc., and conduct hardness tests and tensile strength tests to eliminate substandard raw materials.

● Production Process Control: Precise processing to ensure dimensional accuracy; strictly control surface treatment (surface treatment), zinc layer thickness, and enhance corrosion resistance.

● Performance Testing: Conduct pressure tests, leak tests, and fatigue tests to ensure no leakage and stable performance.

● Final Inspection: 100% full inspection before shipment, checking appearance, dimensions, and performance. Each batch comes with a qualified certificate (qualified certificates).

FAQ

Q1: Why does the joint leak after installation?
A: Common causes include improper tightening (either the joint is tightened too much, damaging the threads/seals, or it is tightened too loosely, resulting in poor sealing); wear or damage to the seals; and mismatch between the joint and the hose specifications. Solution: Tighten according to the standard torque, replace the worn-out seals, and ensure that the joint and the hose are of the same model.

Q2: What are the temperature and pressure ranges for the connector?
A: The working temperature range is -40℃ to 120℃ (for conventional materials). We can also customize a high-pressure model according to customer requirements, which can be adapted to different industrial scenarios.

Q3: Do you have any minimum order quantity (MOQ) requirements for your connectors?
A: It depends on your specific needs. For regular connectors, we usually have them in stock. For custom connectors, the minimum order quantity will be determined based on the type of connector you require.

Q4: Can the connector specifications be customized according to our requirements?
A: Yes, they can.

Q5: Can samples be provided?
A: Yes, we will send you samples. You will need to pay for the sample cost as well as all related shipping fees. The shipping cost will be determined based on the quantity of the samples.
