## Long description

MAGNAPLAST long coupling HTL DN 75 mm model 12320 is a mechanical pipe coupling designed for joining and extending 75 mm diameter plastic drainage and sewer pipes. The HTL long-muff design provides a secure, straight joint that helps align pipe ends and maintain flow integrity in underground drainage systems. The coupling is suitable for repair, replacement or new installations where a DN 75 connection is required.
Advantages
The long-muff construction ensures a stable and concentric connection between pipe sections, reducing the risk of misalignment and leakage. The mechanical design simplifies installation by allowing pipes to be joined without specialized welding or solvent cementing. The product is compatible with standard 75 mm plastic drainage pipes and supports reliable performance in buried drainage applications where a robust joint is needed.
Suitable for
 Repairing damaged sections of 75 mm plastic drainage or sewer pipe
 Extending existing DN 75 underground drainage runs
 Connecting prefabricated pipe sections during renovation or site work
 Temporary or permanent joints in residential and light commercial drainage systems
Key specifications
 Nominal size: DN 75 (75 mm inner diameter compatibility)
 Type: long coupling (long-muff / HTL) for plastic drainage pipes
 Application: underground drainage and sewer connections
 Joint style: mechanical slip-fit long coupling for alignment and secure seating
 Compatibility: designed for standard 75 mm plastic waste, drainage or sewer pipe materials
How to use
Ensure pipe ends to be joined are clean, free of dirt and debris, and cut square. Slide the MAGNAPLAST long coupling onto one pipe end, align the second pipe and push it into the opposite end of the coupling until both pipe ends reach the appropriate insertion depth. Check concentric alignment and correct axial position before backfilling. Follow standard site practices for bedding and cover to avoid point loading on the joint. No heat welding or solvent adhesive is required for the mechanical HTL connection.
Usage recommendations
For reliable performance, confirm pipe material compatibility and insertion depth as specified by the pipe manufacturer. Use correct bedding and backfill procedures for buried drainage runs and avoid sharp point loads at the joint. Inspect joints visually after assembly and before covering with soil; where required by local codes, perform a pressure or water test on the section to verify leak-tightness.
