Seal test plug for PEX pipe TI Group 32 x 3.0 mm blue

TI Group seal test plug for PEX pipe, designed for 32 x 3.0 mm tubing, provides a temporary pressure-tight seal to support leak testing and commissioning of PEX systems. The blue test plug is intended for use during installation and maintenance to isolate a section of piping for pressure testing, flushing, or temporary blocking while work is carried out. Constructed for compatibility with cross-linked polyethylene (PEX) pipe of the stated dimensions, the plug enables controlled testing without permanent modification to the system.

Advantages

The test plug offers a secure, removable seal that simplifies pressure testing of 32 x 3.0 mm PEX lines. Its geometry and sealing surfaces are matched to PEX material to reduce the risk of damage during insertion and removal. The plug’s temporary nature allows quick installation and removal for repeated use on multiple sections of piping. The blue color provides clear visual identification on-site, helping distinguish test points during commissioning and maintenance activities.

Suitable for

• Leak testing and pressure testing of PEX pipe sections
• Commissioning and system flushing of 32 x 3.0 mm PEX installations
• Temporary isolation of pipe sections during repairs or alterations
• On-site verification of fittings and joint integrity in PEX networks

Key specifications

• Compatible pipe outer diameter and wall: 32 x 3.0 mm PEX tubing
• Color: blue for visual identification
• Function: removable, temporary pressure-tight sealing for testing
• Application: suitable for installation, maintenance, flushing and pressure testing

How to use

Before use, ensure the pipe end and surrounding area are clean and free of debris. Insert the test plug into the open end of the 32 x 3.0 mm PEX pipe until the plug seats evenly and the sealing surface contacts the pipe wall. Apply the required test pressure according to applicable standards and monitor the isolated section for leaks. After testing or flushing is complete, release any residual pressure, then carefully withdraw the plug. Inspect the pipe and plug sealing surface for damage before reuse.

Usage recommendations

Use the plug only with compatible 32 x 3.0 mm PEX tubing and follow local pressure testing procedures. Avoid excessive insertion force and do not use the plug as a permanent fitting. Store the plug clean and dry when not in use and inspect it regularly for wear or damage before each application.
