FAQ

What does F-F-F mean in the Female Thread Tee F-F-F Type?
F-F-F stands for Female-Female-Female, meaning all three ports carry internal threads. This makes the fitting suitable for fully threaded piping systems where no welding is required and periodic disassembly is anticipated.
What is the maximum working pressure and temperature for this fitting?
This fitting is rated Class 150. The operating temperature range is -20°C to 220°C. If your application exceeds these parameters, contact our engineering team with your working conditions for a compatibility assessment.
How do I choose between SS304 and SS316 for my application?
SS304 is suitable for most neutral media including water, air, and mild process fluids. SS316 should be specified when the medium contains chloride ions, acids, or other aggressive chemicals - particularly in marine, chemical processing, or coastal environments where pitting corrosion is a risk.
What is your lead time for standard sizes?
Lead time depends on order quantity and size range. Please contact us with your full requirements and we will provide a confirmed delivery schedule.
