The flare-nut wrench is a specific type of wrench with five sides. It is open-ended so that it can be used for hexagonal nuts and fittings. The head has a 15-degree angle with grooves so that the wrench fits tightly over different sized flare fittings and hex nuts. Many flare-nut wrenches are double-sided.
Can you use a regular wrench on a flare nut?
What does flare nut mean?
During assembly, a flare nut is used to secure the flared tubing’s tapered end to the also tapered fitting, producing a pressure-resistant, leak-tight seal. Flared connections offer a high degree of long-term reliability and for this reason are often used in mission-critical and inaccessible locations.
Is a flare nut wrench and line wrench the same?
Brake line wrenches (flare nut wrenches or simply line wrenches) serve a specific purpose. Domestic cars often use 7/16-inch and imports 10 mm. Brake line wrenches (often called flare nut wrenches or simply line wrenches) serve a specific purpose in a mechanic’s toolbox.
What does a flare nut look like?
Flare nut wrenches are a type of open-ended wrench that’s intended for use with hexagonal nuts and fittings, which are sometimes referred to as flare fittings. Visually, they resemble box or ratchet wrenches but with an open head instead of a closed loop.
Where should flare nut spanner should not to be used?
Unlike 12-point ring spanners, 12-point flare nut spanners are not suitable for use on square fastener heads.
How does a flare nut work?
A nut draws the flared tubing against a correspondingly shaped fitting, creating an extremely strong joint. The primary advantage of flare connections is that they form a relatively large contact area, making a reliable seal that’s resistant to damage from vibration.
What do flaring tools have?
Flaring tools consist of three main components: a metal bar with holed presets that fit different pipe or tube sizes, a screw with a handle that goes into the pipe opening to expand it as needed, and a simple metal piece that fits into the handle and enables rotation by the user.
What is a crows foot wrench?
Crowfoot wrenches (also known as tight clearance offset sockets or crowfoot socket wrenches) are open-end type wrenches without a handle or shaft. Wrenches can access fasteners from the top and side and in tight spaces where a regular open-end wrench can’t reach.
What type of flare is best for brake lines?
All brake lines need to be double flared, due to the high hydraulic pressure. If your brakes leak or the hoses crack, it could prove to be fatal. Single flared lines are suitable for low-pressure lines in other applications, but not your vehicle’s brakes.
What is a crows foot tool?
Crowfoot wrenches are open-end sockets that come in handy when reaching around obstacles. They work where common 6pt and 12pt sockets and wrenches simply cannot fit. The crowfoot wrench above is shown attached to a ratchet with a short extension for extra reach.
What is a combination wrench?
Definition of combination wrench : a wrench with one open end and one socket end.
When would you use an adjustable spanner?
Adjustable spanners are used in a variety of trades for a variety of jobs, though they are primarily used to tighten and loosen fastenings of all sizes. The beauty of them is that you can use this one tool on a variety of different sized fasteners.
What is a line spanner?
A Very Useful Mechanics Tool If you are working with any type of fitting that is in-line – such as a brake line, fuel line, or any type of cable – a line wrench can be a life saver. To use a line wrench, just slip the open part of the wrench over the line, then slide it onto the hex part of the fitting.
Do flare fittings need sealant?
Thread sealant must be used when the threads themselves make the seal, as in normal pipe threads. But if the function of the threads is simply to hold two sealing surfaces together, then the threads should not be sealed.
Can you reuse a flare fitting?
Though industry generally accepts that JIC 37° flare fittings are reusable, they may not always be reliable when reused. The cone and flare seat against one another to create a complete mechanical seal between the male and female fitting.
Do flare fittings need Teflon tape?
Just what got tape applied? The threads in a flare fitting are NOT tapered and do not need to be sealed. The seal is between the flared end of the pipe/tube and the tapered face of the other side of the fitting. All the threaded collar does is supply force to create a seal between the opposite tapers of the two ends.
Do you put gas tape on flare fittings?
Do not use Teflon ® tape or pipe sealant on any flare ends because you will not obtain a leak-free seal. Keep flare end of fitting free of grease, oil and thread sealant. Use a wrench only on the hex surfaces of the fittings.
Is a flare fitting a compression fitting?
Flare fittings are a type of compression fitting used with metal tubing, usually soft steel, ductile (soft) copper and aluminum, though other materials are also used. Tube flaring is a type of forging operation, and is usually a cold working procedure. … JIC fittings are typically steel or stainless steel.
What is a flare tool?
What are Flaring Tools? Flaring tools use pressure to make a fabricated mechanical joint for joining or sealing copper tubing with a flare connection. Flaring allows you to connect tubes to each other or another kind of fitting. Flared ends tend to have an approximately conical shape.
What are two types of flaring tools?
Two types of flaring tools are used to make flares on tubing: the impact type and the rolling type.
