Product details

The 22U-139 pipe donut is designed to connect 1-1/2" sch 40/STD PVC pipe into a 2" cast iron hub using a compression seal. Engineered for a precise fit, it creates a secure, leak-resistant connection without the need for grout or adhesives. Ideal for DWV applications, it ensures long-term performance while simplifying installation in both new construction and repair work.

Compression seal technology. Creates a tight, leak-resistant seal by compressing between the pipe and hub—eliminating the need for messy grouts or sealants.

Compatible with multiple materials. Designed for use with cast iron hubs and PVC (sch 40/std) pipe, making it a versatile solution for DWV system connections.

Specs and codes. Complies with ASTM d5926, ASTM c1173 and uniform plumbing code (UPC)
