Q1: Are you a trading company or a source manufacturer?
A: We are a leading source manufacturer with 25 years of expertise in pneumatic components. Our 15,000square meters facility in Ningbo is equipped with 200+ precision CNC machines and 65+ automated assembly lines, delivering an annual capacity of over 50 million units.

Q2:How to order the product I need?
A: Make an inquiry - customize drawings and samples - use scenario notification - receive our product design proposals - negotiate details - confirm samples - sign contract and pay deposit - mass production - get the goods ready - deliver - further cooperation.

Q3: How do you guarantee the fittings won't leak under high pressure?
A: We enforce a strict "Zero-Leakage" standard. Every ISAIAH fitting undergoes 100% pressure-drop leak testing and CCD vision inspection before shipping. By maintaining an extreme +/-0.5mm machining tolerance and using premium seals (e.g.,NBR), we ensure industrial-grade reliability.

Q4: How can I easily identify the correct thread types (NPT,BSPT, Metric) during installation? 
A: To eliminate thread confusion - a common industry pain point - we utilize Laser-Etched Coding. The exact specification (e.g., 1/4 NPT) is permanently laser-marked on the fitting body, ensuring quick identification and preventing equipment damage from mismatched threads.

Q5: Do you offer fittings suitable for special environments like food processing or cleanrooms? 
A: Yes. In addition to standard brass and PBT fittings, we specialize in high-precision 316L Stainless Steel fittings (FDA compliant for food & medical), PFA cleanroom connectors for semiconductors, and chemical-resistant valves.

Q6: Do you support OEM/ODM and custom private labeling?
A: Absolutely. As a National Standard Setter in the pneumatic industry, our R&D team can customize solutions based on your drawings. We also offer private labeling, laser-engraved logos, and bulk industrial packaging to help build your brand.

Q7: What is your Minimum Order Quantity (MOQ)? Can I get samples first? 
A: We support a highly flexible supply chain. Standard stock items have a low MOQ (50 pcs) for Ready-To-Ship (RTS) orders. Free samples are available for quality evaluation; you only need to cover the global express freight.

Q8: What is your standard lead time for global delivery? 
A: Thanks to our massive vertical warehousing and automated production, standard orders are typically dispatched within 7-15 days. For large-scale customized OEM orders, the lead time is usually negotiated between 30-60 days.

Q9: What kind of after-sales support do you provide? 
A: We treat our clients as long-term partners. 
We provide 24/7 rapid response support, lifetime technical guidance for pneumatic system integration, and a solid replacement policy for any verified manufacturing defects.

Q10:How to make the payment?
A: We accept T/T
