90° Long Sweep Elbow for 3" Pipe

This Zoro Select cast-iron elbow provides a 90-degree long-radius bend for 3-inch piping systems. The socket-by-socket design accepts pipe on both ends with a 3 13/32-inch socket depth. Rated Class 20 with bitumen coating, it suits gravity-flow drainage where smooth directional changes reduce turbulence.

Replaces Tight-Radius Fittings in Drainage Runs

Use this long-sweep elbow instead of short-radius bends when the layout allows the longer centre-to-end dimension. The gentle curve lowers flow resistance and minimizes blockage risk in horizontal-to-vertical transitions. It is not suited for pressurised systems or installations that demand a compact fitting envelope.

Fits Cast-Iron Soil Stacks with Socket Joints

The fitting connects directly to 3-inch cast-iron pipe using lead-and-oakum or compression gasket joints — no adapter required. Its bitumen coating protects the iron during handling and in corrosive soils. Installers must verify that the 3 3/8-inch centre-to-face dimension clears surrounding structure before assembly.

Questions about this item

What pipe size and socket depth does the 3-inch long sweep elbow require?

The elbow fits 3-inch pipe with a 3 13/32-inch socket depth on each end for a secure socket connection.

How do you join the cast-iron elbow to the pipe, and which step is often missed?

Clean both socket ends, apply lead and oakum or an approved compression gasket, then drive the joint home; the step most often skipped is fully seating the pipe to the bottom of the socket.

When should the bitumen-coated gray cast iron elbow be inspected or replaced?

Inspect the bitumen coating annually for cracks or flaking; replace the fitting if corrosion penetrates the Class 20 iron or if joint leakage appears.
