New grey c looked Fernco coupler

[Bmusgrove]

Went to the supply store to get a new 1 1/2 to 1 1/4 Fernco coupling. My old one is made of a thick heavy black material like a stiff rubber. The new ones are made out of a thinner more flexible grey material. It feels as if would tear very easily. These are Fernco branded items.

Any idea on why the change? The only reason I am replacing the 23 year old one is I had to pull it to raise the height f type tub drain when I replaced the tub. The old oneseems to be in good condition, but as long as it was accessible....

I don't see it written, but the gray seem to be lighter duty. I did not find application information. I doubt these are compliant with regular codes.

They have always made couplings out of that material. They are usually sold in hardware and big box stores. Your old one was the kind sold to professionals.

First I apologize for not proofreading the title. Very bad grammr. The local wholesale plumbing supply said the grey is all he can get in that size. I did manage to find the older black coupling in the correct size but the 1 1/4 end is actually larger than the new grey one and my old black one. The the great and old pone fit snug and the new one is real sloppy. You can see daylight all the way around the pipe. Wonder if thats because ut us thin wall PVC? It being used on a slip joint PVC bathtub drain kit. By slip going I am talking abut the same type of adjustable joints you see on your sink drains.
