## Long description

The TDM Brass inner sleeve is a precision-engineered plumbing fitting designed to facilitate the connection of pipes with varying diameters. Crafted from high-quality brass, this component serves as a reliable adapter for water supply and heating systems, ensuring a secure and leak-proof transition between 1/2 inch and 3/4 inch threaded connections. Its robust build quality offers long-term durability and resistance to the stresses typically found in residential and commercial plumbing environments.

The primary benefit of this brass inner sleeve is its exceptional resistance to corrosion and thermal expansion, which are critical factors in maintaining system integrity over time. The precision-cut internal threads ensure a tight seal, reducing the risk of leaks and minimizing the need for frequent maintenance. Because it is manufactured from high-grade brass, it provides a stable and long-lasting solution that performs consistently under varying pressure conditions, making it a dependable choice for both professional installers and DIY enthusiasts.

Professional plumbing installations requiring durable brass fittings
When it may not be suitable

How to use
To install the TDM Brass inner sleeve, ensure that the pipe ends are clean and free of debris. Apply an appropriate thread sealant, such as PTFE tape or a liquid pipe sealant, to the male threads of the pipes being connected. Carefully thread the sleeve onto the 1/2 inch pipe end and tighten it using a suitable wrench, ensuring not to overtighten to avoid damaging the threads. Once secure, attach the 3/4 inch pipe component to the other side of the sleeve, tightening it firmly to complete the connection. After installation, pressurize the system slowly to check for any signs of leakage.
What to consider before purchase
Verify the thread sizes of your existing pipes to ensure compatibility
Check the compatibility of brass with the fluid being transported
Ensure you have the necessary tools, such as an adjustable wrench, for installation
Confirm that the pressure and temperature requirements of your system align with brass fitting standards
Usage recommendations
Always inspect the threads for any damage before installation and use a high-quality sealant to ensure a permanent, leak-free connection. Avoid using excessive force during tightening to maintain the structural integrity of the brass threads.
