About this item

THIS PRODUCT REPLACES ITEM 635480

The 21420 Rubber Coupling is a premium-grade, flexible pipe connector designed to join two 3-inch pipes with unmatched reliability and ease. Constructed from durable, chemical-resistant rubber and reinforced with corrosion-proof stainless-steel bands, this coupling delivers a watertight seal ideal for residential, commercial, and industrial plumbing systems.

Whether you're repairing, replacing, or transitioning between pipe materials, this coupling is engineered to handle the job with long wear resistance, self-tightening performance, and code-compliant durability. It’s compatible with Schedule 40 pipe systems and works with cast iron, PVC, ABS, copper, and steel pipes.

Key Features & Benefits

  • Universal Fit: Connects 3" pipes of various materials including cast iron, PVC, ABS, copper, and steel.

  • Stainless Steel Bands: Rust-resistant clamps provide strong, long-lasting sealing force.
  • Leak-Proof Seal: Prevents infiltration and exfiltration in both gravity-flow and low-pressure systems.
