Frequently Asked Questions

Q: What is the difference between O-Ring and Flare seals in pipe couplings?

O-Ring seals utilize a rubber ring to create a tight seal via compression, ideal for high-pressure hydraulic systems. Flare seals use a flared end of the tube to create a metal-to-metal seal, often used in AC and fuel lines.

Q: Which coupling size should I choose for standard automotive AC pipes?

Depending on the vehicle model, common sizes include #6, #8, and #10. We recommend checking your existing hose diameter and matching it with our FT series specifications.

Q: Are these aluminum joints suitable for corrosive environments?

Yes, our high-grade aluminum joints are designed for excellent corrosion resistance. For extreme conditions, we also offer joints with iron caps and specialized coatings.

Q: Can these couplings be used with sewer cleaning hoses?

Absolutely. Our robust coupling designs are compatible with heavy-duty rubber hoses used in sewer cleaning and industrial drainage systems.

Q: What does the UNF designation mean for the screw model?

UNF stands for Unified Fine Thread, a standard specification that ensures a tighter fit and better vibration resistance compared to coarse threads.

Q: Do you provide custom angles other than 45° and 90°?

While our standard catalog focuses on Straight, 45°, and 90°, we can accommodate custom manufacturing requests based on your specific technical drawings.
