Frequently Asked Questions

What shipping methods do you offer, and how long is the delivery time?

We provide multiple shipping options: 1) Courier (DHL/UPS/FedEx): 3–7 working days for small parcels; 2) Air freight: 7–15 working days; 3) Sea freight: 20–45 working days. Delivery time varies by destination and shipping method.

How many materials can you provide?

There are several different materials available for the connector and cable. We typically use PVC or nylon material for the connector, and PVC, rubber, or silicone material for the cable. We can also choose materials according to your specific requirements.

What is rated current?

Rated current, also known as operating current, is the current at which the connector can work properly under the rated voltage. During the aviation plug design process, thermal design of the connector is used to meet the rated current requirements. As current flows through the contacts, heat is generated due to conductor resistance and contact resistance. When the heat exceeds a certain limit, the plug's insulation may be damaged, the surface coating may soften, and failure can occur.

I’ve been buying waterproof connectors for outdoor industrial equipment for years, and this batch is by far the best I’ve ever purchased. The build quality feels really solid, no cheap plastic at all. The IP rating is real—we installed them outside months ago, exposed to rain and sun every day, and not a single drop of water got inside. The sales team was super patient before I ordered; they answered all my technical questions clearly and even helped me pick the right model for my project. After-sales support is also great, they reply fast and solve problems quickly.

As someone who works on outdoor electrical projects regularly, I really value reliable and durable components. These connectors exceeded my expectations in every way. They are easy to install without requiring special tools, fit tightly, and maintain a stable connection at all times. What impressed me most is their excellent waterproof and anti-corrosion performance; even after months of outdoor use, they still look and function like new. On top of that, the customer service is outstanding. The seller was friendly, patient, and knowledgeable during pre-sale consultation and continued to provide timely support after my purchase. I highly recommend this product to anyone who needs stable and waterproof connectors for long-term use.

The self-locking waterproof connectors work great for our rainwater control units. I appreciate that the supplier pointed out potential assembly risks in advance instead of just selling goods. Quality is consistent between samples and bulk order. A trustworthy partner.
