Questions about this item

What size copper tube and male pipe thread does the 1 in C x MNPT fitting connect?

The wrot-copper adapter joins a 1 in copper tube to a 1 in MNPT pipe thread.

How do you make the copper-to-thread joint without leaks?

Clean the tube end, apply flux, slide the C end on, sweat-solder it, then thread the MNPT end into the female fitting with pipe sealant.

When should the trap be replaced given its pressure and temperature limits?

Replace it if corrosion, cracking or leakage appears after prolonged exposure near the 494 psi at 100 °F or the 400 °F upper temperature limit.
