Flare tool instructions

Don't use compression fittings on gas connections at all as most codes do not allow it nor do we recommend it. Brass and copper pipe or tubing must not be used where the gas contains more than an average of 0.

Since natural gas can contain some hydrogen sulfide, the brass flare fittings we offer are not recommended. Galvanized and black steel pipe and fittings can be used if it is standard weight Schedule 40 or thicker.

SAE Society of Automotive Engineer standardized flare fittings were used for natural gas and propane flexible gas connections. SAE Flare fittings and IPS nipples into flexible gas connectors which then would not properly seal causing a small gas leak. The flare threads have 16 threads per inch. 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.

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.

Step 1: Cut your copper or aluminum using a tube cutter to ensure a clean cut - hacksaws and other cutting tools can make for an uneven cut or burrs, which will compromise the flare.

Step 2: Use a deburring tool or abrasive cloth to remove any burrs and debris in and around the pipe end. Step 3: Slide the flare nut onto the pipe, with the tapered end facing away from the end of the pipe to be flared. The nuts need to be on the pipe before both ends are flared.

Step 4: Insert the pipe into the corresponding hole in the die block. Step 7: Place the yoke onto the die block - it should hook or clamp into place on the underside of the block.

Step 8: Position it so that the cone is directly above the pipe to be flared. Turn the handle to move the cone toward the pipe. Keep the halves of the tool parallel to each other as you tighten. Turn the adapter over , coat with a small amount of brake fluid and insert into the tube.

Place the flaring tool on the tubing clamp, making sure the screw point is centered on the adapter and the flaring tool is locked on the tubing clamp. Turn the screw clockwise until the adapter bottoms out of the tubing clamp. Final tightening is easier if you clamp the tool in a vise if you have one. Loosen the screw and remove the adapter. The tubing end should have a bubble look at this point. Position the flaring tool with the point entering the tubing end and centered.

Turn the screw clockwise and tighten until the cone is bottomed out completely. Remove the flaring tool and inspect the tubing end. The flare should be even all around with no cracks or gaps.

Remove the tubing from the clamp. Lowell is a freelance writer who has been writing professionally since June , with articles appearing on various websites.
