Mission Rubber MR56 44 ARC WD Flex-Seal® Arc Shielded Adjustable Sewer Repair Couplings

Product Description

The MISSION RUBBER MR56 44 ARC WD Flex-Seal® Arc Shielded Adjustable Sewer Repair Couplings connect 4" Cast Iron or Plastic pipe to 4" Cast Iron or Plastic pipe. These high-performance sewer repair couplings are for non-pressure, gravity flow applications and are recommended for underground installations. They are easy to install and reuse.

• Increased band tension secures pipe ends, forming a watertight, root-proof seal, impervious to infiltration and exfiltration.
• Thick, stainless steel shield controls load bearing between coupling and pipe surface, opposing shear forces while maintaining pipe alignment.
• Stainless steel components resist corrosion in marine applications, poorly aerated/moist soils, contaminated grounds conditions, and chloride, sulfates or bicarbonates in ground water.

Product Highlights

The Flex-Seal® Arc couplings provide a leak-proof, rigid, and durable solution for sewer repair. They are anti-corrosive, adaptable, and sustainable, with independent clamp tightening for different pipe diameters.
