Frequently Asked Questions (FAQ)
Q1: Are your 18mm hydraulic fittings compatible with both metric and imperial systems?
A: Yes. We offer a wide range of thread types, including metric (M), BSPP (G), BSPT (R), and SAE (JIC). It is crucial to specify the required thread standard and size when ordering to ensure perfect compatibility with your existing ports and hoses.
Q2: What is the main difference between O-ring face seal (ORFS) and bite-type fittings for 18mm tubing?
A: ORFS fittings use a soft seal (O-ring) compressed between two flat faces, providing an excellent static seal resistant to vibration. Bite-type fittings (like DIN 2353) use a cutting ring that bites into the tubing, creating a strong mechanical grip and seal. The choice depends on system pressure, vibration levels, and reassembly frequency.
Q3: Can I use carbon steel fittings in a corrosive environment?
A: For mildly corrosive environments, carbon steel fittings with a high-quality zinc plating offer good protection. For highly corrosive applications (e.g., marine, chemical processing, or outdoor exposure), we strongly recommend our 316 stainless steel 18mm hydraulic fittings for maximum longevity and performance.
Q4: Do you provide pressure rating certifications for your fittings?
A: Absolutely. Our fittings are manufactured to international standards that define their pressure ratings. We can provide material certifications and test reports upon request to support your quality assurance and compliance documentation.
Q5: What is your minimum order quantity (MOQ) and lead time?
A: We support flexible ordering with low MOQs for standard items to accommodate both large projects and maintenance needs. For in-stock 18mm hydraulic fittings, lead time is typically very short. For large custom orders, our sales team will provide a precise timeline based on your specifications.
