Frequently Asked Questions
O-Ring fittings use an elastomeric seal to create a leak-proof barrier, ideal for vacuum or low-to-medium pressure. Flare fittings rely on a metal-to-metal seal created by flaring the tube end, typically used for higher pressure hydraulic applications.
Yes, our couplings are specifically designed for automotive applications, including power steering and AC pipes, using industry-standard UNF threads to ensure compatibility.
The choice depends on your routing space. A 90° coupling is best for sharp turns in tight corners, while a 45° coupling provides a gentler bend to reduce fluid turbulence and hose stress.
We use high-quality Aluminum alloys for the main body, which naturally resist corrosion, and treated iron caps for strength, ensuring longevity in humid or salty environments.
While we provide a comprehensive range from #5/16 to #12, we can accommodate custom specifications for large-scale industrial rubber and plastic product orders.
Our high-strength couplings are suitable for various hose types; however, for sewer cleaning hoses, we recommend our reinforced quick joints to handle the heavy-duty wear and tear associated with that industry.
