Questions about this item

What copper tube size must already be in place for the 617 4 cap to fit?

The cap is made for a 4 in nominal tube with a 4-1/8 in outside diameter, so that exact copper tube must be present for a solder joint.

Can the cap handle the pressure and temperature of an existing hydronic loop?

It is rated to 293 psi at 100 °F and a temperature range of -20 °F to 400 °F, covering typical hydronic conditions.

How do I confirm the joint is sound after soldering the cap?

Pressurise the system to its working pressure — up to 293 psi — and inspect the soldered joint for leaks.
