What is the purpose of ProPress fittings?

ProPress fittings are specifically designed for connecting wet pipes without the need to dry them beforehand. This feature allows for efficient installations in situations where shutting off the water supply might not be feasible, making it particularly advantageous in both residential and commercial settings where time and convenience are critical.

The technology behind ProPress fittings involves a sealing mechanism that employs an O-ring to ensure a leak-free connection while accommodating the presence of water. This is a significant advantage over traditional methods like sweating, which require the pipes to be dry and free of moisture for proper adhesion and sealing.

In contrast, joining dry pipes, repairing leaks, or using sweat joints with copper pipes are methods that either require preparation or are not compatible with the unique qualities of ProPress fittings. Thus, understanding the specific application and advantage of ProPress fittings clarifies their primary purpose in plumbing and piping systems.
