What Adapter For helps you join two things that don’t fit: a garden hose and a pipe, a shutoff valve and a faucet, one brand of drip tubing and another. Pick what you have and what you’re connecting it to, and it names the part that fits.
Where we get our information from
Every size on the site comes from a published standard (such as the National Bureau of Standards thread tables) or from a manufacturer’s own spec sheet, catalog or installation guide. Each page lists its sources. If we can’t find a size in a source we trust, we leave it out rather than guess.
Why sizes are confusing
Most plumbing and irrigation parts are sold by a nominal size, a name that isn’t a measurement. That’s why the site starts from what you can see and measure: Identify it turns where a part is, a coin or a tape reading into the size printed on the package.
Our other sites
What Adapter For is part of a small family of single-question sites.
- What Drill Bit: drill bits, pilot holes and hole saws, including what size hole saw to use for a pipe.
