What is the primary function of compression joints in plumbing?

The primary function of compression joints in plumbing is to connect pipes or fittings. These joints create a secure interconnection between two sections of pipe, allowing for the transfer of fluids with minimal leakage. The mechanism of compression fittings typically involves a metal or plastic ring that compresses against the pipe as the fitting is tightened, creating a firm grip without requiring soldering or welding.

While creating water-tight seals and providing flexibility are essential aspects of plumbing systems, compression joints specifically excel at establishing a strong, reliable connection between components. They are particularly useful in situations where access may be limited and where disassembly of the joint may be needed for maintenance or replacement. Reducing pressure in the pipes is not a primary function of compression joints; instead, they are designed to handle the pressures present in standard plumbing applications effectively.
