This ATC brass connector steps a 3/8" compression end down to a 1/8" MPT connection, making it a handy transition piece for plumbing and heating lines where pipe sizes don't match up. Rated to 250 PSI and 250°F, it holds up under real working conditions, and the lead-free brass construction meets today's water-safety standards. Works with brass, copper, and iron pipe, so it fits into most existing systems without extra adapters.

You're going to open the other tab. Everybody does. We'd rather say so than pretend otherwise — so open it. We'll wait.
When you're over there, check four things before you click buy.
The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.
Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Atc. A third-party marketplace seller usually isn't.
Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

Sometimes you'll find it for less. Sometimes you'll find it for more. On a lot of brands the number is identical everywhere it's sold legitimately — the manufacturer sets a minimum advertised price and every authorized dealer holds it. When a price sits well under that, it's worth asking why before it's worth celebrating.

Whether you're a contractor, property manager, facility team, or government buyer — one application unlocks pricing, terms, and service built for the way you actually buy.
Apply for a Pro Account Or call (866) 469-8556Every product comes directly from the trusted manufacturers you know — sourced directly through authorized manufacturer channels — the trusted brands your neighborhood hardware store carries.
When something's better bought down the street, we'll tell you — and point you to a local store that stocks it. We list independent retailers at no cost to most of them. We're not a marketplace, not a chain, not a faceless warehouse.
We come from the hardware world — the people answering your questions know the products, not just a script. Questions about fit, compatibility, or what a job actually calls for? You'll reach a real person, not a chatbot or a contracted call center.
The world's fast and convenient now, and it's only getting faster — same-day, next-hour, a screen where a face used to be. That's not going away, and we're not pretending it should. We live here too. We can move when you need us — most orders land in under two business days.
But the store on the corner probably has it on the shelf right now. And it was never only about speed. It's the person who knows the product and knows your name. It's what that store puts back into the town — the people it hires, the team it sponsors, the neighbor it shows up for. That's the part a warehouse can't ship.
These places have anchored their communities for generations. Keeping them around for the next two hundred and fifty years matters more than any single sale — ours included. So we'll be the convenient option when you need one, and we'll point you local whenever it makes sense. If it's better bought down the street, we'll say so.
If you're rooting for a handful of giant corporations to swallow every small store on Main Street — we'll be straight with you: we're not your shop. And that's alright. We were never trying to be everyone's.
We support local hardware stores.
We don't replace them.
