Instrument Tee
What are Instrument Tees?

Instrument tees are T-shaped fittings that allow a fluid line to split into two or merge from two lines into one. These fittings are used in pressure and flow monitoring systems to enable sampling, redirection, or sensor integration in the flow path.
Asiad Steel Industries is a dependable supplier of precision-engineered instrument tees, offering robust construction, excellent sealing properties, and compatibility with demanding system designs. These tees are essential in hydraulic, pneumatic, and process control pipelines across sectors.

Do you have questions?
Do you offer both equal and reducing tees?
Yes, we offer both variants with options for various thread types and materials.
What is the difference between a tube tee and a pipe tee?
Tube tees are for OD tubing systems, while pipe tees are used in nominal pipe size (NPS) piping systems.
Are tees pressure tested before delivery?
Yes, all instrument fittings including tees are 100% hydrostatically or pneumatically tested.
Can tees be used with double ferrule tube fittings?
Absolutely. Our tees are fully compatible with standard double ferrule compression fittings.
