Why Choose This GHT to NPT Adapter?

What "GHT" and "NPT" Actually Mean

GHT (Garden Hose Thread) is the standard threading on U.S. garden hoses. NPT (National Pipe Thread) is used on pipes, faucets, and plumbing fittings, with tapered threads for a tighter seal. These two standards don't connect directly—that's why this adapter exists.

How to Confirm You Need This Adapter

Check both ends. Your garden hose end should be 3/4" GHT male (threads outside). The pipe or fitting you're connecting to should be 1" NPT female (threads inside). If either side is different, you'll need a different adapter from our NPT to GHT collection.

Why the Swivel Base Matters

A fixed adapter locks in one position—you have to twist the whole hose to tighten it. The swivel base lets the adapter rotate freely, so you can hand-tighten without twisting the hose or straining the connection. It also helps prevent kinks during use.

Brass vs Plastic

Plastic adapters crack under UV, freeze-thaw cycles, and high pressure. Solid brass handles all three without deforming or leaking—especially important if the adapter stays outdoors year-round.

Installation Tips

Hand-tighten first, then a quarter turn with a wrench if needed—don't overtighten. The included rubber washer handles the seal on the GHT side. For the NPT side, wrap the male threads with 2–3 turns of PTFE tape (not included) to improve the seal.

A: Yes. It lets you hand-tighten without twisting the hose, and helps prevent kinks during use.

Q3: What if it leaks?
