Frequently Asked Questions
What is the difference between olive and flared compression fittings?
Olive type uses a compression ring for sealing; flared type requires tube end flaring for stronger hold in high-vibration environments.
Are AirFluid compression fittings reusable?
Many are reusable, especially with replaceable olives/ferrules. Contact us for specific model guidance.
Which material is best for corrosive environments?
Stainless steel provides the highest corrosion resistance.
Do your DOT fittings meet transportation standards?
Yes, our brass DOT compression fittings are fully certified for air brake systems.
