Warranty Terms

1. Warranty Period
We provide a 12-month quality warranty for our rotary joints, calculated from the date of shipment from our factory. If the buyer does not raise a written objection within 7 days of receipt of the goods, the product shall be deemed free from defects in appearance and quantity at the time of delivery.

2. Scope of Warranty
The warranty covers performance failures caused by defects in materials or manufacturing/workmanship quality, provided that such failures are not attributable to normal wear and tear or improper use.

The warranty does NOT cover the following:
(1) Improper installation, commissioning, or operation;
(2) Actual operating conditions (pressure, temperature, rotational speed) exceeding the product's technical specifications;
(3) Normal consumption and aging of wear-and-tear parts and consumables (including but not limited to seals, gaskets, O-rings, etc.);
(4) Failure to perform regular maintenance;
(5) External factors such as media corrosion, electrochemical effects, ingress of foreign substances, etc.;
(6) Man-made damage, operational errors, accidents, or force majeure (fire, flood, earthquake, war, etc.);
(7) Normal wear and tear during normal operation of the equipment.

3. Warranty Claim Handling Procedure
We do not apply a rigid one-size-fits-all procedure. All warranty events are reviewed and handled on a case-by-case basis according to the actual situation. When you need to file a warranty claim, please follow the general steps below:
(1) The buyer shall notify us by email within 15 working days from the date on which the failure is discovered or should have been discovered. Failure to notify within such period shall be deemed as the failure not being covered by the warranty or as a waiver of the buyer's right to claim.
(2) The notification shall include: order number, product serial number, purchase date, actual operating parameters, detailed failure description, together with clear photos or short videos. If the information provided is incomplete, we reserve the right to request supplementary information, and the time for supplementation shall not be counted in the processing period.

(3) Our technical team will determine the root cause of the failure based on the information you provide. In some cases, we may request further information or require the return of samples for further analysis.
(4) If it is determined that the failure falls within the warranty scope, we will provide one or more of the following remedial measures (at our option): free repair, replacement of faulty parts, supply of replacement spare parts of the same specifications, or other mutually agreed solutions.
(5) If the failure is determined to be outside the warranty scope, we are still able to offer you spare parts and technical support at preferential prices.

4. Warranty Period After Repair
Replacement parts installed during the warranty period shall have a warranty period that expires with the remaining warranty period of the original equipment; it shall not be recalculated. The warranty for repair service shall be 90 days from the date of completion of the repair (applicable only to the same failure).

5. Limitation of Liability
Under no circumstances shall we be liable for any incidental, indirect, loss of profit, business interruption, loss of goodwill, or other consequential damages arising from product defects. Our total liability in all cases shall not exceed the contract price of the product giving rise to the claim.
This clause does not exclude mandatory statutory liability for personal injury or property damage caused by our gross negligence or willful misconduct.

6. Governing Law and Dispute Resolution
The interpretation and enforcement of these Warranty Terms shall be governed by the laws of the People's Republic of China. Any dispute arising from these Terms shall be settled through friendly negotiation; if negotiation fails, the dispute shall be submitted to the competent People's Court at our place of jurisdiction for litigation.
