Questions about this item

What comes with the 1" red brass cap and do I need to buy thread sealant separately?

The cap is supplied with pre-applied thread sealant, so no separate sealant or gasket is required for installation.

Which pressure class should I select for a 1" nominal pipe size in a hot water system?

The Class 125 rating supports up to 200 psi at temperatures from -20 °F to 400 °F, covering typical residential hot water lines.

What does the 200 psi rating mean when the cap is installed on a 1" line?

It indicates the maximum continuous operating pressure the cap can safely hold at the full temperature range without leaking or deforming.
