Frequently Asked Questions
Q1: What are the advantages of brass flexible conduit connectors over steel?
Brass flexible conduit connectors offer superior corrosion resistance, better sealing performance due to machined surfaces, non-sparking properties for safety, excellent electrical conductivity for grounding, and natural lubricity for easier installation and swivel action.
Q2: Can swivel connectors be used in vibrating applications?
Yes, our brass swivel connectors are specifically designed for vibrating applications. They feature precision bearings or smooth swivel surfaces that allow continuous movement while maintaining seal integrity and electrical continuity.
