PVC Conduit Screwed Reducer 25mm to 20mm Grey

Description

25mm to 20mm. PVC. Grey. Screwed Conduit Reducer.

The Rylec SR2520C is a 25mm to 20mm grey PVC screwed conduit reducer — the standard fitting for stepping down from a 25mm threaded rigid PVC conduit to a 20mm threaded conduit connection. One end accepts a 25mm screwed conduit, the other provides a 20mm screwed connection, allowing a size transition in the conduit run without additional adaptors. Sold individually — minimum order quantity: 10 pieces.

Where the SR2520C Screwed Reducer Fits

A screwed conduit reducer bridges a diameter change in a threaded rigid PVC conduit system — where a conduit run steps from 25mm down to 20mm at a junction, branch point, or entry. The SR2520C threads directly between the two conduit sizes: the 25mm end receives the larger conduit and the 20mm end connects to the smaller conduit run or a 20mm fitting. This eliminates the need for separate adaptors on each conduit end when a size transition is required mid-run or at an entry point.

Typical applications include sub-board conduit layouts where a main 25mm run branches into 20mm sub-runs serving individual circuits, conduit entries into enclosures where the enclosure entry hole is sized for 20mm but the incoming conduit is 25mm, and any installation where the conduit system changes diameter at a threaded coupling point. The grey PVC construction matches the standard grey rigid conduit system used in Australian residential and commercial electrical installations.

The SR range covers four consecutive size steps: SR2520C (25mm to 20mm), SR3225C (32mm to 25mm), SR4032C (40mm to 32mm), and SR5040C (50mm to 40mm) — each reducing by one standard conduit size step.

Q: What is the difference between a screwed reducer and a plain-to-screwed adaptor?
A: A screwed reducer (SR2520C) connects two threaded conduit sections of different diameters — both ends are threaded. A plain-to-screwed adaptor (PSA series) connects a plain (unthreaded) conduit tube to a threaded fitting or enclosure entry — one end is plain socket, the other is threaded. Use the SR2520C where both conduit sections in the run are threaded, and the PSA series where one section is plain tube.

Q: What is the minimum order quantity for the SR2520C?
A: The minimum order quantity is 10 pieces per order.
