3/4 英寸 NPT 螺紋計量接頭，帶 1 英寸 NPS 螺母 - WS

The NPS nut threads onto my meter without any wobble, and the coupling seat feels solid once snugged down. Exactly the secure connection I needed for this hookup, no leaks on the first test.

Took a chance on this for a water meter hookup and the fit was spot-on—the 3/4 NPT threads engaged cleanly with no wobble, and the 1 inch NPS nut tightened down without forcing it. Flow path stayed unobstructed, exactly what I needed for a straight run.

The threads on this coupling are machined clean enough that it screwed onto my meter without any wobble or cross-threading. I especially appreciate the 1 inch NPS nut on the other end, since it makes the transition to my existing line a lot simpler. Solid, leak-free fit so far.
