Polybutylene or? I could not get a clearer pic. This looks similar to polybutylene piping but ive never seen it with handtightened fittings

Appreciate any help given.

I think you are correct.

[lkage (Larry Kage, CMI)]

Thinkin’ so…

The pb looks off to me, more like 83. It comes off a rusted pressure tank and corroded shutoff valve. Plumber needs to get in there anyways

[mgeorge7 (Michael George)]

Its attached to copper before going up wall, so its easy replacement.

[lkage (Larry Kage, CMI)]

Yeah, the ”P” isn’t right.

[mtimpani (Mark Timpani, CMI)]

looks like it from here

[ddagostino (Dominic DAgostino, CMI HI3957)]

The fittings are from Qest, a once very popular and widely used plumbing component.

A family friend worked at the Fort Wayne Genova warehouse for 40years before they closed about 7 years ago. They never manufactured polybutylene pipe.

For reference, this is an example of PB piping.
