Questions about this item

What size thread sealant or tape is needed for the 3/8 in MNPT threads on this nipple?

Use standard 3/8 in NPT thread sealant or PTFE tape rated for 300 psi at 150 °F; wrap the male threads clockwise before threading into the matching female fittings.

Will the 5/64 in wall thickness and 43/64 in outside diameter match my existing Schedule 40 black steel piping?

Yes, the nipple meets ASTM A-53 Type E and ASTM A-733 Grade B, so its 5/64 in wall and 43/64 in OD are identical to standard Schedule 40 dimensions.

How can I verify the nipple is holding pressure after installation?

Pressurise the system up to 300 psi at 150 °F or 150 psi steam; no leaks at the threaded joints and no visible deformation confirm it is working to its rated limits.
