3-inch DWV flexible elbow

The Fernco PQL-300 is a 3-inch flexible repair elbow designed for drain, waste and vent systems. It connects common household DWV pipes at a 90-degree angle without special tools or fittings. The neoprene rubber construction provides exceptional flexibility for in-wall or tight-space repairs. It fits cast-iron, steel, plastic, lead and copper pipe materials.

Capacity limited to non-pressure DWV use

The fitting handles standard gravity-flow drain, waste and vent connections in residential plumbing. It comfortably replaces elbows or tees cut out at the joint thanks to its extra length. The product runs out at any pressure application; the manufacturer explicitly states it must not be used where internal pressure is present. It is sized for 3-inch nominal pipe only.

Flexible rubber body replaces rigid fittings

The extra-long neoprene rubber body acts as both the elbow and the seal, removing the need for separate couplings or solvent welding. Its flexibility allows alignment adjustments in confined cavities where rigid PVC or metal elbows cannot be manoeuvred. The single-piece design speeds up repair or alteration work on existing DWV lines.

Questions about this item

Will the 3-inch flexible elbow connect to my existing cast-iron drain pipe?

Yes, the flexible neoprene rubber fits cast-iron, steel, plastic, lead, and copper pipe, so it will join your existing 3-inch cast-iron drain without special fittings.

How can I confirm the 90-degree connection is sealed after installation?

Run water through the drain, waste, or vent system and check the joint for leaks; the extra-long rubber body is designed to seal tightly on DWV pipe surfaces.

Does the PQL-300 package include clamps or do I need to buy them separately?

The fitting is sold as a single flexible elbow; stainless-steel band clamps are not included and must be purchased separately to secure the connection.
