Flare Fittings

You won't find a better selection of flare fittings anywhere on the Internet. It is important to use flare fittings when you are dealing with a lot of water pressure going through a pipe or are dealing with high gas distribution. Flare fittings on the end of copper tubing should provide a strong connection to a fixed point with a threaded nipple. PlumbingSupply.com® is your source for hard-to-find fittings. And, as always, there is never a minimum purchase requirement.

  • O.D. Outside diameter of pipe
  • MIPS: Male pipe threads on the outside of fitting
  • FIPS: Female pipe threads on the inside of fitting

Frequently Asked Questions

Q. "Where do you use compression versus flare fittings?"
A. We prefer flare with soft tubing over 3/8"od in size and compression fittings on all hard copper and soft tubing 3/8"od and smaller. Don't use compression fittings on gas connections at all as most codes do not allow it nor do we recommend it.

Q. "Can you provide me with a quote on other brass fittings besides the ones listed above?"
A. Sorry but what we show is what we carry/offer/stock. We do not quote prices on flare fittings that we do not stock.

Q. "Should I use PTFE thread sealing tape or pipe joint compound on my flare threads?"
A. No, you definitely should not. PTFE tape and pipe joint compound (also known as "pipe dope") should only be used on "IPS" ("iron pipe size") threads, which are normal pipe threads. IPS threads make their seal along the threads themselves; when a piece of IPS-threaded pipe is screwed into a fitting, PTFE tape and/or pipe dope is used to assist that seal on the threads. Flare fittings, on the other hand, seal on the beveled ends of the fittings, and so using pipe dope or tape on flare threads could actually prevent the fittings from making an adequate seal.

Q. "Since these are brass fittings do they contain lead?"
A. Most of these fittings do contain a very small amount of lead. Consider that for many years copper fittings and pipe were soldered together with 50% lead and now little lead may be used by law. Same with these brass fittings. There is a small amount of lead in them. The more acidic the water, the more tends to leach out. Should you be concerned? Some would argue that any amount is bad, and they would not use it for potable water. Others argue that plastics will be the new "asbestos" of the future. We don't know, and we cannot recommend these fittings for potable water; but we can say that we ourselves drink our own water from and through these fittings.

Q. "What is the flare degree of the flare fittings you offer?"
A. The fittings we offer are SAE 45° flare with the exception of the 15/16"-16 flare cap found on our Gas-related Products page. The 15/16"-16 are 45° flare, but are not SAE fittings.
