TDM Brass 1670 Press Elbow 20mm x 3/4 inch Female Thread

The TDM Brass 1670 press elbow is a professional-grade plumbing fitting engineered for creating reliable, leak-proof transitions between press-fit piping systems and threaded components. With a 20mm press connection on one end and a 3/4 inch female thread on the other, this elbow allows for a 90-degree change in direction while maintaining structural integrity. Constructed from high-quality brass, it is designed to withstand the rigors of modern water supply and heating installations, providing a robust solution for both residential and commercial plumbing projects.

Advantages

The primary benefit of this press elbow is its exceptional durability and resistance to corrosion, which is inherent to its high-quality brass composition. The precision-engineered press connection ensures a fast and secure installation, significantly reducing labor time compared to traditional soldering or threading methods. Furthermore, the dual-connection design offers versatility, allowing installers to seamlessly integrate modern press-fit piping with existing threaded infrastructure without the need for complex adapters.

Suitable for

• Connecting 20mm press-fit pipes to 3/4 inch threaded valves or fittings
• Residential and commercial water supply systems
• Hydronic heating installations
• Transitions between different piping materials

When it may not be suitable

This fitting is not intended for use with piping systems that do not support standard press-fit technology or for applications involving aggressive chemicals that may react with brass. It should not be used in high-pressure steam systems or environments where the temperature exceeds the rated limits of the press-fit seals.

Key specifications

• Connection A: 20mm press-fit
• Connection B: 3/4 inch female thread
• Material: High-quality brass
• Angle: 90 degrees

How to use

To install the TDM Brass 1670 press elbow, first ensure the pipe end is cut square, deburred, and cleaned of any debris. Insert the pipe into the press end of the fitting until it reaches the stop. Use a compatible press tool with the correct jaw profile to compress the fitting onto the pipe, ensuring a permanent, watertight seal. For the threaded side, apply appropriate thread sealant or PTFE tape to the male component before screwing it into the 3/4 inch female thread, tightening firmly with a wrench to avoid over-torquing.

What to consider before purchase

• Verify the compatibility of your press tool and jaw profile with the fitting
• Ensure the pipe diameter matches the 20mm specification
• Check that the threaded component matches the 3/4 inch female standard
• Confirm the system pressure and temperature requirements are within the fitting's operational range

Usage recommendations

Always inspect the press connection after installation to ensure the fitting is properly seated and the seal is intact. Avoid using excessive force when tightening the threaded connection to prevent damage to the brass threads.
