TDM Brass Inner Sleeve 1 1/4" x 3/4" Threaded Fitting

The TDM Brass inner sleeve 1 1/4" x 3/4" is a professional-grade threaded fitting engineered for secure and efficient plumbing connections. Constructed from high-quality brass, this component provides a robust transition between pipes with different diameters, specifically connecting a 1 1/4-inch internal thread to a 3/4-inch internal thread. Its durable design ensures structural integrity and reliable performance in demanding hydraulic environments.

Advantages

This brass inner sleeve offers exceptional durability and resistance to corrosion, making it a dependable choice for long-term plumbing installations. The precision-machined threads ensure a tight, leak-proof seal, which is essential for maintaining system pressure and preventing water loss. Its compact design allows for easy installation in tight spaces, while the high-quality material composition ensures compatibility with various water supply and heating systems.

Suitable for

• Residential water supply systems
• Heating and cooling piping networks
• Industrial hydraulic applications
• Transitioning between different pipe diameters in threaded plumbing setups

When it may not be suitable

This fitting is not intended for use with pipes that do not feature compatible threaded connections or for systems involving highly corrosive chemicals that may degrade brass over time. It should not be used in high-pressure steam applications exceeding the material's rated temperature and pressure limits.

Key specifications

• Material: Brass
• Connection type: Internal thread to internal thread
• Diameter 1: 1 1/4 inch
• Diameter 2: 3/4 inch

How to use

To install the inner sleeve, ensure that the pipe ends are clean and free of debris. Apply a suitable thread sealant, such as PTFE tape or pipe dope, to the male threaded ends of the pipes being connected. Carefully screw the pipes into the inner sleeve by hand to ensure the threads are properly aligned, then tighten with an appropriate wrench until secure. Avoid overtightening to prevent damage to the threads or the fitting itself.

What to consider before purchase

• Verify the thread type and size of your existing pipes to ensure compatibility.
• Check the pressure and temperature requirements of your specific plumbing system.
• Ensure you have the necessary tools, such as pipe wrenches, for proper installation.

Usage recommendations

Regularly inspect the connection for any signs of moisture or leaks after the initial installation and during routine system maintenance to ensure continued performance.
