I have a collection of 6 inch diameter SDR 35 pvc pipe fittings for sale, leftovers from my drainage job. 3- 6in- 22.5 degree elbows 4- 6in- 45.0 degree elbows 1- 6in - straight connector 1- 6in - End cap There is a total of 9 - 6 inch fittings in all. All of the elbows and fittings have their gaskets intact. That works out to about $5.50 each, a substantial savings from buying new.
