Is this safe to use on my engine????

Can I use these as connectors for my bypass and pcv system?

They are polypropelyne. The only info I can find says that it is chenical resistant but nothing in specific about oil vapor or temperatures.

They are ideal. They are barbed. I tried smashing one with a hammer and it just deformed and then returned to its original shape so I don't see it craking and chipping. They come in tee, elbows, threded adapters and reducers. From 1/2" to 1 1/4".

I found this. The description for the poly is pretty positive.

I'm just looking for a second opinion.

Thanks.

Why bypass the PCV system?

I want to use them for my sc bypass valve AND for my pcv system.

I dunno, but I wonder if that's the same kind of plastic in the 90* fittings that most of us use on our PCV catch tanks/separators. If so, I can tell ya that mine seem to be ok.

Good luck.
