Side Outlet Tees

What are black malleable side outlet tees used for in plumbing?

How They’re Configured

A standard side outlet tee typically has:

• (2) inline openings (run)
• (1) center outlet (like a normal tee)
• (1) extra outlet on the side of the fitting body
• All ends are usually female threaded (FIP).

What They’re Used For

• Adding an extra branch without installing another tee
• Creating compact manifolds
• Gas piping systems
• Hydronic heating systems
• Compressed air lines
• Industrial and mechanical piping

They’re especially helpful when space is tight and you need multiple takeoffs from one location.

Why Black Malleable Iron?

• Strong and impact-resistant
• Good for pressure applications
• Widely approved for gas and heating systems
• Cost-effective compared to steel or stainless

Compared to Using Multiple Fittings

Traditional Method: Tee + nipple + tee (3 fittings)

Side Outlet Tee:

Single fitting does the same job

Fewer fittings = fewer joints and fewer potential leak points.
