Fernco Inc P1059-150 Flexible Coupling 1.5 in Socket Pipe

Product Description

The FERNCO INC P1059-150 is a 1.5-inch flexible coupling designed for socket-to-pipe drain and waste connections. It uses a flexible elastomeric sleeve to join two pipe ends, compensating for minor misalignment and allowing for slight movement within the joint. This coupling is well suited for residential and light commercial plumbing repair and replacement work where rigid couplings are impractical. Licensed plumbers and experienced pipe fitters install this type of fitting when connecting dissimilar pipe materials or when working in confined spaces that restrict rigid joint assembly.

This coupling is applied in drain, waste, and vent (DWV) piping systems where a socket-to-pipe transition is required. It is commonly used during repair scenarios where a section of pipe is replaced without disturbing the surrounding structure. The 1.5-inch size matches standard lavatory drain lines, washing machine standpipes, and similar residential drain applications.

Key Features

• 1.5-inch by 1.5-inch socket-to-pipe connection style for direct replacement work
• Flexible elastomeric construction accommodates minor pipe misalignment
• No special tools required for installation — stainless steel clamps seat with a standard screwdriver or nut driver
• Sold in a package quantity of 20 units per case

Compatibility

Designed as an OEM-style replacement flexible coupling for 1.5-inch DWV piping systems using socket-to-pipe joint configurations.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and local jurisdiction requirements. Shut off water supply and drain the affected line completely before beginning work. Ensure pipe ends are clean, free of burrs, and properly aligned before seating the coupling sleeve and tightening the stainless steel band clamps. Do not overtighten clamps, as excessive force can damage the elastomeric sleeve and compromise the seal.
