1-1/2" 316 Stainless Steel Street Elbow

This 90-degree street elbow connects a 1-1/2" male NPT thread to a 1-1/2" female NPT thread. It is made from 316 stainless steel for corrosion resistance in plumbing and industrial piping systems. The fitting suits Schedule 40 pipe and carries a Class 150 pressure rating. It is designed for installers who need a compact change of direction in a threaded line.

Class 150 rating limits pressure to 300 psi

The Class 150 designation means the maximum operating pressure is 300 psi at ambient temperature. Higher temperatures will reduce the allowable pressure below this figure. The 11.5 threads-per-inch NPT standard governs the seal, so thread engagement and sealant quality determine leak resistance. Installers must verify that system pressure and temperature stay within the Class 150 envelope.

Tapered NPT threads seal with compound or tape

Male and female NPT threads are tapered, so the joint tightens as it is turned. Apply PTFE tape or pipe thread compound to the male threads before assembly to fill the spiral leak path. Over-tightening can crack the female fitting, especially on smaller sizes, so stop when resistance increases sharply. Misaligned pipe runs stress the joint and often cause weeping that sealant cannot fix.

Questions about this item

Should I choose the 1-1/2" MNPT x FNPT version or a different size for my 316 stainless steel piping?

This street elbow is made in 1-1/2 inch MNPT x FNPT with 11.5 threads per inch on both ends, matching Schedule 40 pipe of the same nominal size.

What does the 300 psi maximum operating pressure mean once the elbow is installed in my system?

The 300 psi rating is the highest continuous pressure the Class 150 fitting can handle at ambient temperature with Schedule 40 pipe.

How does the NPT thread standard affect what I can connect to this 316 SS street elbow?

The 11.5 TPI NPT threads seal by taper engagement, so the male end threads into any 1-1/2 inch female NPT port and the female end accepts a 1-1/2 inch male NPT nipple.
