NPT (National Pipe Taper) is the standard in North America, using a tapered thread that seals through deformation. BSP (British Standard Pipe) is common globally and often requires a gasket for a positive seal. Using the wrong thread can cause leaks or system damage. We manufacture both strictly to ASME B1.20.1 and ISO 228 standards.

We offer a wide range, including Stainless Steel (SS316, SS304), Forged Steel (A105), and Brass. We also supply Duplex, Super Duplex, and Monel for highly corrosive environments. We recommend SS316 for most chemical and marine applications.

Our standard MOQ is 50 pieces per size and material, but we are flexible for sample orders or OEM trials. We encourage buyers to start with a small pilot order to validate our fit and finish.

Quality is ensured at every stage: 1) Incoming material inspection (chemical composition & mechanical properties). 2) In-process inspection of threading and sealing faces. 3) 100% pressure testing (hydrostatic & pneumatic) before shipping. 4) Third-party inspection (SGS, BV) is available upon request.

For standard threaded valves (SS or CS), our production lead time is typically 25-35 days. Custom orders or materials (e.g., Duplex) may require 40-50 days. We prioritize high-speed delivery for urgent projects.

Yes. We offer full OEM/ODM services, including custom engraving, painting, specialized packaging, and unique design modifications. Our engineers will work with your team to match your exact specifications.

All threaded ends are protected with plastic caps and wrapped in heavy-duty plastic. Valves are packed in strong plywood crates or cartons suitable for sea freight, ensuring they arrive in perfect condition.
