3 inch Stainless Steel Rain Cap

The 3 inch stainless steel exhaust rain cap is SCL’s most in-demand rain cap size — reflecting the prevalence of the 3 inch exhaust bore across medium-to-large generators, agricultural machinery, crushing and screening plant, and construction equipment throughout the UK and Ireland. The stainless steel construction is the outdoor specification, providing long-term corrosion resistance for rain caps fitted to vertical stacks on equipment operating in exposed conditions — including outdoor generator enclosures, open quarry and construction sites, and agricultural machinery working in all weathers. The gravity-operated hinged cap closes under gravity when the engine stops and opens freely under exhaust gas pressure when it runs, requiring no maintenance or manual operation.
