Flare 3/4 inch copper

[Geo422]

I need to flare a 3/4 inch water supply pipe . I purchased a flaring set with 3/4 inch. But it seems too small.
Is there a specific size to flare 3/4 water supply line?
I got the basic pretty much down . This something I never done but now my curiosity is up on the correct size. Thank everyone George

I think flare tools and flare nut sizes refer to OD rather than nominal ID.

Is that soft tubing you are looking to flare? In that case, I think you would be looking for a 7/8.

If that is hard copper pipe, I don't know if you can flare that.

Type K Copper water tubing is meant for flaring
Copper tubing comes in four different types, based on its wall thickness. The 4 basic types of copper tubing are: Type K, L, M, and DWV. Type K has the thickest diameter compared to other types of copper of any given diameter. Type DWV (drain, waste, and vent) is used mainly for non-pressurized applications. The ideal type for flaring is Type K because it has a thick wall that can withstand enlargement due to flaring, and because of its soft malleable nature. Type L and M copper are meant to be soldered or brazed to join lengths of it together, as they are considered hard copper tubing. Hard copper tubing is most difficult to flare, and is expressly not meant for that purpose.

I use a "hammer flare/swage" to flare 3/4" tubing.

why not buy one of these fittings, converts flare to compression

There are several different brands, but only one basic model.

if your city connection is flare this fittting is way better

Thank you HJ I ordered one and today I flare the copper out . Very easy to do of course with the advice from here. Now I will let you know if the water works accept it or not. George

We flair type L all the time as well as typer K and we ever double flair for higher such as AC compressors

Plumber 69 thank you . Does this fitting have a name? Trying to find it but haven’t yet.
