1-1/2" Schedule 40 Galvanized Steel Nipple

This Anvil 0334534609 pipe nipple connects threaded fittings in air, gas, non-potable water, oil and steam lines. It is built from Grade B welded steel with a black anodized finish and rated for 150 psi at 150 degrees Fahrenheit. The 4-inch overall length suits tight pipe runs where a short male-threaded connector is required.

Threaded Male Ends for Direct Assembly

Both ends feature 1-1/2 inch MNPT threads so the nipple screws straight into compatible female fittings without soldering or special tools. Apply pipe thread sealant or tape to prevent leaks on the tapered threads. Over-tightening can distort the Schedule 40 wall or damage the fitting, so stop when resistance increases sharply.

Verify Pressure, Temperature

Confirm the system operates at or below the 150 psi and 150 °F limits stated for this Schedule 40 nipple. Ensure mating components share the same nominal pipe size and thread standard to avoid mismatched connections. This nipple is not rated for potable water service.

Questions about this item

How can I verify the 1-1/2" MNPT x 4" galvanized steel nipple is correctly seated after threading it into the Schedule 80 fitting?

Hand-tighten the male NPT threads, then apply a wrench for one to two additional turns; the black anodized finish should sit flush with no visible gaps and the joint must hold 150 psi at 150 °F without leakage.

What comes in the box with the Anvil 0334534609 nipple and what extra items are required for installation?

The package contains the single 4-inch welded steel nipple; you must supply pipe thread sealant or tape and a compatible Schedule 80 female fitting separately.

Which schedule rating should I select when the product lists both Schedule 40 and Schedule 80 references?

The nipple itself is manufactured to Schedule 40 dimensions, but it is rated for use with Schedule 80 fittings; choose this version when your system requires Schedule 40 pipe wall thickness mated to Schedule 80 components.
