Frequently Asked Questions
Q: Can you manufacture PVC drainage fittings according to EN standards?
A: Yes, applicable EN requirements can be reviewed for suitable products. The exact standard, product classification, dimensions and joint requirements should be confirmed before production.
Q: Can you supply ASTM PVC drainage fittings?
A: ASTM requirements can be reviewed for suitable PVC DWV products. Buyers should provide the required ASTM specification when requesting a quotation so that the correct dimensional and product requirements can be confirmed.
Q: Can your fittings match pipes from another manufacturer?
A: They may be compatible, but nominal size alone should not be used to confirm compatibility. The pipe standard, outside diameter, joint dimensions and tolerance requirements should be checked.
For an existing pipe system, we recommend providing a technical drawing, pipe specification or physical sample.
Q: Do you support OEM and private-label orders?
A: Yes. OEM options may include product colors, product marking, private-label packaging, barcode labels and customized shipping marks. Customized dimensions and new fitting designs require technical and tooling review.
Q: Can different sizes be mixed in one container?
A: Yes. Mixed-SKU container loading is available according to the final packing and loading plan.
Q: What is the production lead time?
A: Standard production is approximately 15–25 days after order confirmation. The actual lead time depends on order volume, mold availability, customization and production scheduling.
Q: Can I receive samples before placing a bulk order?
A: Yes. Samples can be arranged for product evaluation. Freight and sample arrangements depend on the product and order requirements.
Q: Can you arrange third-party inspection?
A: Yes. Third-party inspection can be arranged by prior agreement, with the inspection scope and acceptance criteria confirmed before inspection.
