Description
A three-way tee fitting in stainless steel with 1/2 in. male NPT connections, used to split one line into two or to combine two returns into a single run.
- Configuration: 3-way tee
- Body material: stainless steel
- Connections: 1/2 in. male NPT (tapered pipe thread)
NPT threads are tapered and seal on thread interference, so each joint needs PTFE tape or a thread sealant rated for your fluid, and each make-and-break cycle wears the thread. Where a joint will be opened repeatedly, the JIC flare version of this same tee is the better choice.
Frequently asked questions
What connection type is this?+
1/2 in. male NPT on all three ports — the tapered US pipe thread. It mates with 1/2 in. female NPT ports and couplings.
Do I need thread sealant?+
Yes. NPT seals on the thread flanks, so use PTFE tape or a liquid thread sealant rated for your fluid and temperature. Keep tape off the first thread so shreds do not enter the line.
What is the body material?+
Stainless steel. The listing does not state the specific grade, so if grade matters for your fluid or for a cleanliness spec, ask us to confirm before ordering.
Is there a pressure rating?+
No pressure or temperature rating is given in the source listing. Do not assume a figure — ask us to confirm it against your service conditions.
What is the difference between this and the JIC version?+
This one is male NPT, a tapered thread that seals with sealant. The JIC version is a 37° flare that seals metal-to-metal and can be broken and re-made cleanly. They are not interchangeable at a joint.
