Copper Press Caps

Installing is simple: you press it onto the cleaned end of a copper tube and crimp it with a press tool. The internal O-ring creates a watertight seal, effectively blocking the flow at that pipe end.

Yes. Like other SurePress fittings, press caps are rated for up to 300 psi quickfitting.com , which means they can safely be used for pressure testing new lines or permanently sealing off a live line in commercial applications. They are just as reliable as soldered caps, but much faster to install.

Common scenarios include capping pipes during renovations, temporarily sealing a line while reconfiguring plumbing, or permanently capping a branch that might be extended later. In commercial installs, they save time when you need to quickly cap and move on, without waiting for cool-down as with solder.
