I need a 6"-to-4" PVC reducer fitting... ?

[Essohbe]

I have specs for a 6" chamber and 3" barrel. I can get away with a 4" chamber but it's almost as long as the barrel, I want to use a 6" chamber instead. Does anyone here know a cheap source of 6" reducer fittings? Grainger has them but they're about $18 a piece.

Savko.com has a 6" x 4" bushing for $12, and they have very competitive pricings

once you get to 6" prices skyrocket on pvc fittings

lol, McMaster is usually a good bit more expensive than other suppliers (but they have uuurthang). A 6x4" bushing is almost 23 bucks.
