Found some new fittings at auction near me.
Anyone have any experience with this brand?
What makes the stainless steel fittings so special? Would this be bad for residential?

I'm renovating and any help is appreciated. Thanks!

Parker is a major brand, used in industry all over the place. Those are heavy duty fittings.
Your pics look like without threads they must be welding fittings?

Those are Parker weld socket fittings.

I have a friend that threatened to plumb his house with it. He’s nuts, a Weldor. Said he could get the materials free...🤔

Good catch. Probably. I'll have to take a closer look in-person at show day. Thanks for the spot!

Welded connections? That's specialized stuff, not saleable to the average Joe.
After you find plumbers that do commercial work, how do you reach them?
Do you intend to peddle the fittings office to office?
If you buy them, good Luck moving them .

I had some very costly P-H fittings on my car wash equipment, but these Weld-Loc ones are for exotic uses in the chemical and nuclear industries. Properly done they have ratings from 3500psi up to nearly 10,000. As @Twowaxhack definitely not for residential, and not likely for most industrial use either. Takes a skilled welder to do perfect welds on these.

Mine were costly enough, but they were threaded and relatively low pressure--only 1500 psi rating. They were also 316 SS.

Unless you know the purchasing agent at the local nuclear power plant or some chemical plant, pass on them...
