Obviously, flare-nut wrenches are best for tightening or loosening hexagonal nuts and fittings. This makes them versatile and useful, especially for working on cars or plumbing. The most popular industry to use flare-nut wrenches is the automobile industry.
What are flare nuts used for?
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 line wrench the same as a flare nut wrench?
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.
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 do flare fittings seal?
Design: The 37° flare AN seal is used for sealing tubing to end connections. It requires the end of the tube to have a nut slipped onto it and then flared out using a special tool. To seal properly, the nut is threaded into a flare fitting which clamps the flared tube in between the nut and flare fitting.
What is a flare nut fitting?
A flare fitting has a tapered end that fits into a flared piece of tubing and is secured in place with a sleeve and flare fitting (threaded nut) to produce a pressure-resistant, leak-tight seal.
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.
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 combination wrench?
Definition of combination wrench : a wrench with one open end and one socket end.
Are flare nut wrenches necessary?
Because of the shape of flare-nut wrenches, this wrench type is absolutely necessary if you work in the automobile or plumbing industries. The open 5-sided design ensures that you can easily grip nuts so you can maximally tighten or loosen them.
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.
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 are ignition wrenches?
Ignition wrenches are small wrenches used on engine parts and other automotive applications. They are designed with an angled head, allowing for access in tight areas.
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.
What is the difference between flare fitting and compression fitting?
Fittings: Generally speaking, compression outlets are used for water and compressed air lines, where slight leakage isn’t going to cause too much of a problem. Flared outlets are used for gas and high-pressure lines, where even a little leakage can cause major problems if left unattended.
Can flare fittings be used for water?
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.
What is the difference between an open end and a box end wrench?
They come either separately or in a combination form, with one end being an open wrench, while the other is boxed. The box end has a tendency to slip off, while the open end allows more versatility since it needs only to contact two sides of the nut or bolt.
What is an offset socket wrench?
Deep offset wrenches are double box end wrenches with angled and offset ends. Each end will often be a different size. Deep offset wrenches are typically used for reaching over or around obstructions to reach fasteners.
Why do flare fittings leak?
Bad flare, burrs on the pipe, wrong size flare, can all cause a flare fitting to leak. The most common reason they leak is because of us overtightening them. I once had a tech tighten one to the point that it blow off during pressure testing. If you don’t deburr, the flare may not seat properly.
What is a flare seat?
Flared seats refer to the protruding “nose cone” on a male thread, but also the corresponding inverted flare in a female thread. These sealing systems all share a common trait in that there is a metal-to-metal seal created where the male and female surfaces contact (not including the threads).
Can aluminum be flared?
Aluminum Tubing It can be flared and used with Earl’s tube nuts, and tube sleeves or an adapter can be welded onto the end(s) of the tubes. Aluminum is easy to cut and flare and you can even polish it to a high sheen.
