Question 1

Q1: What materials do you use for your high-pressure water seals?

Accepted Answer

A: We primarily use high-grade materials such as NBR (Nitrile), FKM (Viton), PTFE (Teflon), and Kevlar-reinforced fabrics. For specialized applications, we also offer materials capable of withstanding temperatures up to 200°C and pressures exceeding 500 bar.

Question 2

Q2: Are your seal kits compatible with major pump brands?

Accepted Answer

A: Yes. We specialize in producing replacement seal kits for leading brands including Interpump, Annovi Reverberi (AR), HAWK, Comet, and Bertolini. All our kits are engineered to meet or exceed original equipment (OEM) specifications.

Question 3

Q3: How do you ensure the quality of your seals during production?

Accepted Answer

A: We implement a strict quality control process:
1. Raw Material Inspection: Testing the hardness and elasticity of rubber batches.
2. In-process Monitoring: Precision control of vulcanization time and temperature.
3. Final Inspection: 100% visual inspection and random dimension testing using digital calipers and projectors.

Question 4

Q4: Can you provide custom sealing solutions based on drawings or samples?

Accepted Answer

A: Absolutely. We offer comprehensive OEM/ODM services. If you have a unique requirement or a discontinued part, simply send us your technical drawings or a physical sample, and our engineering team will develop a precise mold for production.

Question 5

Q5: What is your Minimum Order Quantity (MOQ)?

Accepted Answer

A: For standard stock items (like common O-rings or U-cups), we have no strict MOQ—even a few sets are fine. For custom-molded parts or specialized fabric-reinforced seals, the MOQ varies depending on the complexity, typically starting from 50–100 pieces.

Question 6

Q6: Do you provide free samples?

Accepted Answer

A: Yes, we can provide free samples for most standard sizes. The customer only needs to cover the express shipping cost (via DHL, FedEx, or UPS).

Question 7

Q7: What information do I need to provide for a quotation?

Accepted Answer

A: To give you an accurate quote, please provide:
1. Dimensions (ID x OD x Height).
2. Working Conditions (Temperature, Pressure, and Medium—e.g., oil, water, or chemicals).
3. Estimated Quantity.

Question 8

Q8: How long is the typical lead time for an export order?

Accepted Answer

A: 
- Stock items: Shipped within 2–3 working days.
- Mass production: Typically 10–15 days.
- Custom molds: Requires an additional 7–10 days for mold fabrication.

Question 9

Q9: How are the products packaged for international shipping?

Accepted Answer

A: Seals are sensitive to dust and deformation. We use vacuum-sealed plastic bags as primary packaging, followed by reinforced, multi-layer corrugated boxes. For large sea freight orders, we use fumigation-free pallets with shrink-wrap protection.

Question 10

Q10: What are your accepted payment terms?

Accepted Answer

A: We generally accept T/T (Telegraphic Transfer), L/C at sight, and Western Union. For new customers, we typically require a 30% deposit and a 70% balance before shipment.
