A4MBT4-W tee 1/4T x 1/4G x 1/4T for water treatment installations. It has two quick connectors for a 1/4" (6.4 mm) hose and an external thread of 1/4". It allows for the splitting of the water line, e.g., in under-sink systems and reverse osmosis. The hose is installed by pushing it in fully, without twisting; Teflon tape is only required on the threaded part.

Description
A4MBT4-W tee connector 1/4T x 1/4GZ x 1/4T is a practical component for splitting water lines in water treatment installations such as reverse osmosis, osmosis filter, reverse osmosis system, or an under-sink water filter. The model is equipped with two quick connectors for 1/4" (6.4 mm) tubing and a 1/4" male thread, making it suitable wherever a secure and convenient flow split is needed. Tubing installation is quick and does not require tightening, and PTFE tape is used only on the threaded part.

Tee connector for water distribution in filtration systems
A4MBT4-W is designed for use in installations where two sections of 1/4" tubing need to be connected with a 1/4" threaded connection. This solution is often used in domestic water treatment setups, especially in under-sink systems and RO installations.
The tee connector makes it easier to expand and reorganize an existing setup, helping route water lines neatly and functionally in places where tightness, ease of installation, and compatibility with popular 1/4" tubing matter.
Application
The A4MBT4-W tee connector is used in under-sink water treatment systems, including reverse osmosis filter installations and other setups where a water filtration system is used.
Example applications include:
- splitting mineralized and demineralized water,
- splitting water to the tank in reverse osmosis,
- other configurations requiring division of the water line in the installation.
Thanks to this design, the component can be helpful both when building a new setup and when upgrading an already operating water treatment unit or a circuit in which water is being mineralized.
Construction and connection method
The tee connector has two quick-connect fittings for 1/4" (6.4 mm) tubing and one 1/4" male thread. This configuration makes it easy to connect flexible lines to a threaded component without using complicated adapters.
To secure the tubing, insert it into the fitting until it stops. There is no need for additional tightening or sealing the quick-connect sockets with PTFE tape. Additional sealing with PTFE tape is required only on the threaded part.
During installation, the tubing should be inserted straight in until fully seated. PTFE tape is used only on the 1/4" male thread. There is no need for additional tightening or wrapping tape on quick-connect joints.
Key benefits
- allows convenient splitting of the water line in the installation,
- fits popular 1/4" (6.4 mm) tubing,
- equipped with a 1/4" male thread,
- speeds up installation thanks to quick connectors,
- does not require tightening the tubing during connection,
- works well in installations such as a water filter, osmosis filter, and reverse osmosis system,
- made of high-quality plastic.
Material
The A4MBT4-W model is made of high-quality plastic. This material is commonly used in connecting elements of water treatment systems due to its low weight, ease of installation, and good compatibility with typical tubing installations.
