Product Q&A

Q:How does the multi-layer sealing mechanism work?

The sealer expands rapidly under grouting pressure (0.5-2.0MPa). If pressure exceeds 2.0MPa, a blasting valve explodes to fill the middle section, achieving multi-layer sealing.

Q:What is the warranty period for this product?

We provide a 12-month warranty for all kinds of products. Defective accessories are replaced for free in the next order.

Q:Can this product be customized?

Yes, we offer full customization including working pressure (5MPa), sealing depth (6m), sealing diameter (100mm), and weight (10kg).

Q:What is the delivery time after payment?

Delivery is arranged within about 7 working days after receipt of payment.

Q:How do I place an order?

Step 1: Tell us model and quantity. Step 2: Confirm PI details. Step 3: Arrange payment. Step 4: We deliver within the stipulated time.
