7. Frequently Asked Questions (FAQ)
Q1: Are your 8mm hydraulic fittings compatible with both metric and imperial systems?
A: Yes. Our range includes fittings with 8mm tube ends paired with various thread types, including metric (e.g., M12x1.5), BSPP (G), and NPT. Always verify the specific thread and sealing type required for your application to ensure a proper seal.
Q2: What is the main difference between the 24° cone and O-ring seal types for 8mm fittings?
A: The 24° cone (DIN/ISO) is a metal-to-metal seal that is highly durable and resistant to high temperatures and pressures. O-ring seal fittings (ORFS/ORB) use a soft seal (the O-ring) contained in a groove, providing excellent leak-free performance and are more forgiving to vibration and minor misalignment.
Q3: Can I use carbon steel fittings with a phosphate coating in a marine environment?
A: While phosphate coating offers good general corrosion resistance, for highly corrosive environments like marine applications, we strongly recommend specifying our 316 stainless steel 8mm hydraulic fittings for maximum longevity and performance.
Q4: Do you offer custom configurations or branding on these fittings?
A: Absolutely. For large OEM projects, we provide custom machining, special plating, and private labeling services. Contact our sales team to discuss your specific requirements for volume orders.
Q5: What certifications do your products hold?
A: Our manufacturing process is ISO 9001 certified. Our fittings are produced to meet international dimensional and performance standards (ISO, DIN, SAE). Material certifications (3.1) are available upon request for traceability and quality assurance.
