Internal sewer plug MAGNAPLAST HTM 110 mm (model 12530)

MAGNAPLAST HTM internal sewer plug for 110 mm pipes (model 12530) is a compact inflatable test and sealing device intended for temporary closure of domestic drainage and sewage lines. Designed to fit 110 mm diameter connections, the plug enables pressure testing, maintenance isolation and controlled blockage of internal plumbing sections. The product is suitable for use by professionals and informed DIY users where reliable, temporary sealing is required without permanent modifications to the pipework.

Advantages

The MAGNAPLAST HTM plug provides a secure, inflatable seal that conforms to the internal pipe wall, reducing risk of leaks during pressure tests or maintenance. Its compact size allows insertion into tight access points and simple removal after use. The design minimizes installation complexity and permits repeated use in different locations. Materials used are resistant to typical wastewater conditions encountered in domestic systems.

Suitable for

• Pressure testing of 110 mm domestic drainage and sewer branches
• Temporary isolation of sections during pipe maintenance or repair
• Blocking flow for controlled leak testing or inspection
• Use in renovation or replacement work where non-permanent sealing is needed

Key specifications

• Designed for nominal pipe diameter: 110 mm
• Type: internal inflatable sewer/test plug
• Application: temporary sealing and pressure testing of internal drainage
• Suitable media: domestic wastewater and drainage effluent
• Intended users: professional plumbers and competent DIY installers

How to use

Insert the deflated plug into the 110 mm pipe section to the location where sealing is required, following safe access and support practices. Inflate the plug gradually using a hand pump or compressed-air source equipped with appropriate pressure control, monitoring for a secure, even seal against the pipe wall. Perform pressure tests or maintenance tasks while observing applicable test pressures and local plumbing standards. After the task is complete, release the air, deflate the plug, and remove it carefully from the pipe. Inspect the plug for damage before storage.

Usage recommendations

Before inflating, verify pipe cleanliness and remove debris that could damage the sealing surface. Use a pressure gauge and stay within recommended test pressures for 110 mm domestic systems. Store the plug dry and away from direct sunlight to preserve material properties.
