About C-Loong

Factory exterior

C-Loong Precision Industry (Shenzhen) is an automotive A/C parts supply partner serving distributors, wholesalers, repair networks and professional buyers worldwide. Our product range covers automotive A/C compressors, compressor control valves, expansion valves, compressor clutches and related components, with support for product matching, sample confirmation and bulk-order coordination.

We understand that every order carries more than a purchasing cost—it also affects your delivery schedule, inventory planning and reputation with downstream customers. For this reason, we review OE numbers, compressor models, vehicle applications, product photos and key specifications before order confirmation, and remain involved when questions arise after delivery. Our standard MOQ starts from 20 pieces per model, regular lead time is 7–14 days, and confirmed in-stock products can be dispatched on the same day.

Company Values


Verify Before We Assume

Before an order moves forward, we confirm OE numbers, vehicle applications, product specifications and other key configuration details with the customer. This careful process helps reduce fitment errors, returns and avoidable delays.

Clear, Direct Communication

We explain product capabilities, order requirements and any known limitations clearly. If information is missing or requires further confirmation, we ask before production or shipment instead of guessing.

Quality You Can Verify

We believe quality should be demonstrated through inspection, not broad claims. Our checks focus on product condition, fitment details, operating performance and the specific requirements of each shipment.

Built for Long-Term Supply

We focus on lasting working relationships rather than one-time sales. Our role is to help customers maintain consistent product matching, coordinate repeat orders and secure a dependable supply of automotive A/C parts.

From Production to Delivery

Production line

Production line

A highly efficient and stable production line enables more accurate delivery schedules and greater control over quality.

生产

Automated Assembly

Automated assembly helps reduce batch-to-batch variation and ensures that the quality of every product meets standards.

Control Valve Testing

Electrical Performance Testing

Electrical performance testing helps identify issues prior to delivery, thereby reducing after-sales problems and ensuring product quality and performance.

库存

Parts Inventory

An ample supply of spare parts helps accelerate order processing and urgent restocking, preventing delivery schedules and fulfillment from being disrupted by exceptional circumstances.

包装

Package

Reliable and complete packaging ensures the product is protected during transit, minimizing bumps or other damage.

transportation

Transportation

We offer various transportation methods—including express, air, sea, and land freight—to meet your delivery timeframe and budget requirements.

Quality Control

Every stage—from raw materials to final shipment—undergoes multiple inspections to minimize quality issues; our current pass rate reaches 99.97%.

Control Valve Testing

Incoming Material Check

Incoming materials and key components are checked against the confirmed product specifications. Depending on the component, checks may include its type, dimensions, condition, appearance and product reference. This helps prevent unsuitable or inconsistent inputs from entering production.

Production Process Check

At relevant stages of production, key dimensions, cleanliness, assembly position and appearance are checked. Identifying deviations early allows them to be corrected before they continue into later operations or affect more products in the batch.

Product Testing

Testing is selected according to the product type and function. Relevant checks may include compressor operation and leakage, valve sealing, flow or electrical response, and clutch coil or engagement performance. Test items and acceptance criteria are confirmed according to the product and order requirements.

Final Inspection

Before shipment, finished products are checked against the confirmed specifications and applicable performance requirements. Compressor inspection follows GB/T 21360-2018 and QC/T 660-2019. Only products that meet the required criteria are released for shipment.

Our Team

A responsive team that helps you identify the right parts, reduce ordering risks and keep each purchase moving from initial enquiry to repeat order.

Faster Part Confirmation

Send us the OE number, vehicle make, model and year, product photos or a physical sample. We compare the available information and verify the critical specifications before the order is confirmed.

Fewer Fitment Problems

We cross-check details such as the compressor model, pulley type, connector, mounting points and control valve configuration. This careful review helps reduce mismatched parts, returns and fitment-related claims.

Clear Updates at Every Stage

You receive clear updates on specifications, samples, production, packaging and shipment. If a detail requires attention, we raise it early so it can be resolved before it affects delivery.

Practical Technical Support

If a product or installation issue arises, we review the available installation details, product photos, videos, pressure readings and test results. This helps narrow down possible causes and identify the next checks.

More Consistent Repeat Orders

Once product specifications and order requirements are confirmed, they can be recorded for future reference. This gives repeat orders a clearer starting point and helps maintain consistency across purchases.
