Press fit bronze elbows provide reliable, leak-proof joints due to the precise mechanical compression applied during installation. The fitting is pressed onto the pipe, deforming both slightly to form a tight seal that resists internal pressure and external forces.

The design of press fit systems often includes O-rings or sealing elements inside the fitting to enhance the watertight seal. This ensures that joints maintain their integrity over long periods, reducing the risk of leaks, which can cause water damage, system inefficiencies, and costly repairs.

Bronze is a durable material that withstands mechanical stresses such as vibration, pressure fluctuations, and impact. These properties make press fit bronze elbows suitable for industrial environments where pipes are subject to dynamic forces.

Compared to plastic or less robust metals, bronze fittings are less prone to cracking or deformation under stress. This mechanical strength ensures system reliability, even in harsh conditions such as high-pressure steam lines or chilled water systems.

Press fit bronze elbows can be used with different types of pipes, including copper, stainless steel, and PEX (cross-linked polyethylene) tubing, depending on the specific design and standards. This compatibility allows for flexibility in system design and retrofitting existing pipelines without extensive replacement.

Using bronze elbows with PEX or copper pipes, for example, combines the strength and corrosion resistance of bronze with the flexibility and cost-effectiveness of plastic or copper tubing, resulting in an optimized piping solution.

Because press fitting does not require soldering or welding, there is no need for open flames or heat sources during installation. This safety advantage minimizes fire risks, making press fit bronze elbows ideal for use in occupied buildings, confined spaces, or locations with combustible materials.

The absence of heat also allows installation in environments where flammable gases or liquids are present, broadening the application possibilities and enhancing worker safety.

The press-connect joining method (sometimes called press-fit) was patented in Europe in the late 1950s and continues to be used successfully there. The method and associated fittings and tools were introduced in the United States in the late 1990s. Since then, there has been growing acceptance, and those using the method experience excellent results.
Press-connect joining takes advantage of copper or copper alloy"s excellent malleability and its proven increased strength when cold worked. The joints rely on the sealing capability of a special fitting that contains an elastomeric gasket or seal (such as EPDM) and the proper use of an approved pressing tool and jaws.
