SharkBite Fittings

SharkBite fittings, or push-to-connect fittings as they’re often called, have really taken off in the U.S. lately, especially with folks who love doing their own home repairs. They’re pitched as quick, easy, and—get this—tool-free plumbing solutions. But here’s the million-dollar question: Are they genuinely safe and reliable for the long haul?

### How SharkBite Fittings Work
So, here’s the deal. SharkBite fittings feature a mix of stainless-steel teeth and an internal O-ring that work together to create a watertight seal.

Let’s unpack this, thread by thread.

What Is NPT Anyway?
NPT stands for National Pipe Tapered Thread. It’s basically a standard we use here in the U.S. for threaded fittings in plumbing, gas lines, and air systems.

These threads are tapered, which means they get tighter as you screw them together. They’re designed to create a mechanical seal, often using good ol’ pipe tape or some thread sealant. You’ll typically find them in steel, brass, and plastic fittings.

Just a few keywords to keep in mind: NPT fitting, NPT pipe, NPT threads, check valve, globe valve, plug valve.

But here’s the kicker...

Most Copper Fittings Are Not NPT
