7. Frequently Asked Questions (FAQ)
Q1: How do I select the correct fitting type and thread standard for my application?
A: The selection depends on your system's pressure rating, fluid type, existing equipment standards, and geographic location. Key factors are the sealing method (flare, O-ring, compression) and thread form (tapered vs. parallel). Our technical team can guide you through this process to ensure compatibility and performance.
Q2: Can you supply fittings that are certified to specific industry standards?
A: Yes. As professional hydraulic fittings suppliers, we provide products with full traceability and certifications, including material test reports (MTRs), to meet requirements for industries like offshore, mining, and defense where compliance is critical.
Q3: What is your minimum order quantity (MOQ) and lead time?
A: We offer flexible MOQs to support both large OEM projects and smaller MRO needs. Standard product lead times are competitive, and we maintain strategic stock for fast-moving items. Custom orders are quoted based on specifications and quantity.
Q4: How do your fittings ensure a leak-free connection?
A: Leak prevention is achieved through precision machining of sealing surfaces (e.g., the 37° flare seat or O-ring groove), correct thread engagement, and the use of proper assembly torque. Our fittings are designed to create a metal-to-metal seal or a controlled elastomeric seal that withstands system pulsation and vibration.
Q5: Do you offer packaging suitable for international export and corrosion protection?
A: Absolutely. We offer VCI (Vapor Corrosion Inhibitor) packaging, individual plastic caps/plugs, and sturdy export cartons to ensure products arrive at your destination in perfect, corrosion-free condition, ready for immediate use or storage.
