Went out and looked at my again, It is 1" male N.P.T. on each end about 15" over all length, looks like a fiberglass muffler except for the ends that are pipe nipples. I can take a picture but have no idea how to post it, actually it looks like a glass pak muffler sticking straight up from the head of my compressor with the air filter on top. The Co's name is North Central Air Downs Ks. Phone # 913 454 3409. Real nice people, when they delivered my compressor I was injured from a accident and they put it in my garage and moved it into position and even put it on the oak blocks for me. If you want pictures I can get my son to take some and he can post for me.
