FAQ

1. What is the structural difference between D-type press fittings and S-type press fittings?

The primary difference lies in the socket design. The D-type press fitting does not have an extended straight section at the end of its socket, whereas the S-type press fitting features this extended straight section to accommodate specific installation requirements.

2. What are the applicable media for this stainless steel press coupling?

These D-type press fittings are highly suitable for various food-grade media. Common applications include drinking water systems, milk processing lines, beverage production, and beer brewing facilities, ensuring safe and hygienic fluid transfer for your projects.

3. Can I visit your factory before placing an order?

Yes, you are very welcome to visit our manufacturing facility. If an on-site visit is not convenient for your schedule, we can also provide detailed videos or arrange a virtual tour of our production workshop and office environment to help you verify our manufacturing capabilities and quality control standards.

4. How are the press fittings packaged for delivery?

To ensure the products arrive safely and without damage, our standard packaging involves a strict three-step process: first, the fittings are sealed in protective plastic bags to prevent contamination; second, they are packed into sturdy cartons; and finally, they are secured in durable wooden boxes suitable for secure international shipping.
