What does NPSM Loose Mean?  NPSM stands for National Pipe Straight Mechanical.  Loose means that we machine these on the higher end of the tolerance to account for Weld distortion to the neck and expansion and contraction throughout the seasons.

Finish

The cap looks very nicely produced, but the finish on the aluminum is dull (like a hardware store mill finish). Expected a nicer polish or machined finish for the cap.

The cap is beautiful and threads so smoothly. Boyd was the only place I could find this size. Order delivery was very fast and tons of communication during the process. Thanks!
