Frequently Asked Questions

Q: Which coupling is best for high-pressure brake hose systems?

For high-pressure systems, we recommend our O-Ring sealed series (e.g., FT2001-FT2015) as they provide a superior airtight seal compared to standard flare fittings.

Q: What is the difference between the Al joint with iron cap and the Al outer screw?

The iron cap provides additional reinforcement at the stress point of the connection, while the Al outer screw offers a lightweight, corrosion-resistant alternative for specific applications.

Q: Are these couplings compatible with standard rubber hose protector sleeves?

Yes, our couplings are designed to integrate perfectly with rubber hose protector spiral guards and protection sleeves to ensure maximum hose longevity.

Q: How do I choose between 45° and 90° couplings?

The choice depends on your spatial constraints. 90° couplings are ideal for tight corners, while 45° couplings reduce stress on the hose by providing a more gradual bend.

Q: Do you provide bulk custom sizes for industrial rubber pipe manufacturing?

Yes, we specialize in the rubber products industry and can manufacture couplings to your specific UNF or custom thread specifications for bulk orders.

Q: What is the typical application for the Sewer Cleaning Hose coupling?

Sewer cleaning requires high-torque, leak-proof connections that can withstand abrasive environments. Our reinforced coupling series ensures a secure lock during high-pressure flushing.
