Questions about this item

How much heat or noise does the 304 stainless steel hex bushing generate during continuous operation?

The fitting is a passive component with no moving parts, so it produces no noise and negligible heat regardless of how long the system runs.

What existing pipe threads must I already have for this MNPT x FNPT bushing to install correctly?

You need a female NPT thread of 1-1/2 in on one side and a male NPT thread of 1/2 in on the other, both conforming to ANSME B 1.20.1.

Will this Class 150 bushing rated for 300 psi work safely with older piping rated to MSS-SP-114?

Yes, it meets MSS-SP-114 Class 150 pressure ratings and conforms to ASTM-A-351, so it matches the same standard used by older Class 150 piping.
