There are two types of fitting to make a soldered pipe joint, one which comes with a ring of solder already inside each end of the fitting, called a Yorkshire fitting, and the other, an end feed fitting. … You will then need to apply a liberal amount of flux to both the pipe and the fitting.
What is Yorkshire flux used for?
Yorkshire flux and Traditional Craftsman’s flux are specially formulated for jointing copper tubes with Yorkshire integral solder ring fittings. All fluxes are, to some extent, corrosive, but special care should be taken with so-called self cleaning fluxes.
Can you overheat a Yorkshire fitting?
If you did overheat a Yorkshire fitting, you will be at risk of a leak, so I would recommend you have a roll of lead free solder at hand. Also wire solder is good for adding flux to the joint as you heat it.
Do you need flux to sweat copper pipe?
After a thorough cleaning, coat the pipe and fitting with flux before heating the joint. This helps solder flow into the joint. You may find two or three kinds of flux on the shelf. We recommend tinning flux.Why are they called Yorkshire Fittings?
The “Yorkshire” brand of plumbing fittings belonged to Yorkshire Copper Works Ltd of Leeds. This company was founded in 1909 on the site of the former Elmore’s Depositing Co., to manufacture copper and brass tubes for boilers.
Can you solder without flux?
When soldering circuit boards, or other electrical / electronic devices, yes – you need to use flux. Fortunately, almost all solder for electronics use has an internal core of flux, so you usually don’t need to add more.
Do I need flux for pre soldered joints?
You must always remember to use flux to help the solder to run around the joint in a capillary action. This will ensure a tight, even and watertight pipe join. This will also prevent oxidisation.
What is the difference between end feed and solder ring?
Both of these types of fittings use molten solder to make a joint between a copper pipe and a copper (or occasionally brass) fitting. But the key difference is that with end feed fittings, the installer has to provide the solder. Solder ring fittings, as the name suggests, provide their own solder!Do you need flux for copper to copper?
Remember that copper to copper brazing does not require a flux. Here are a few common combinations: Using Stay-Brite® Solder – Stay-Clean® Soldering Fluxes.
Do you add solder to Yorkshire Fittings?The application of solder is still a good idea with Yorkshire fittings to be absolutely sure of a good joint. Make sure you have a damp rag handy, and after a few seconds, to allow the solder to set, carefully wipe the joint round. This will cool it and clean it.
Article first time published onHow reliable are Yorkshire Fittings?
Users of Yorkshire integral solder ring fittings can be confident that they are purchasing an established product with a proven reputation for reliability and quality which spans more than eighty years.
Can you use Yorkshire Fittings for gas?
Yorkshire Flux, like Traditional Craftsman’s, will maintain it’s consistency and can be used with all types and sizes of soft solder fittings. However, it must not be used for gas applications.
Can you reuse solder ring fittings?
No problem to re-use if you’re taking one of the pipes out. Just heat when tinned and re-solder.
What is a Yorkshire elbow?
The Yorkshire YPS12 integral solder ring (ISR) 15mm 90° elbow is made of copper. … Suitable for use in a wide range of applications, this fitting incorporates an integral solder ring and has been designed for jointing copper tubes to BS EN 1057 (R220, R250 and R290).
Can you solder Tectite fittings?
TECTITE fittings should not be installed in soldered or brazed piping systems until after the components have been allowed to cool. The plumbing system should be cool to the touch at the time of installation. CAUTION, BE PATIENT, BURN HAZARD! Soldering or brazing should not be done within 12” of a TECTITE fitting.
How strong is lead free solder?
A: Lead-free solder has a higher melting point, which makes it harder to work with – it’s 217C for lead-free compared to 183C for lead alloys.
How long should you heat copper pipe for solder?
Five to 10 seconds of heating with a MAPP gas torch is all that’s required before you can feed solder into most 1/2- to 3/4-in. pipes and fittings.
Can I use Vaseline as flux?
Can You Use Vaseline as Flux? Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won’t corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond.
Is soldering paste necessary?
For a good soldered joint, the proper amount of solder paste must be used. Too much paste may result in a short circuit; too little may result in poor electrical connection or physical strength.
Is soldering paste the same as flux?
Solder paste flux is different than liquid flux in both physical form and activity level. Solder paste flux typically contains 60-80% by weight active ingredients, compared with liquid flux’s 2-25%. By weight, a mixed solder paste commonly consists of 90% metal.
Can I solder copper without flux?
You “can” solder copper without flux, without scraping (sanding or filing) clean the two surfaces, and without ensuring there is a close even fit between the two surfaces for the molten solder to wick into and provide a quality joint.
When soldering Why should flux be used?
The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.
What is the advantage of swaging over joining tubing with a fitting?
Swaging tools use pressure to expand or stretch the end of a piece of copper tubing so it can fit over another of the same diameter and make a permanent brazed connection.
What type of flux is used in plumbing?
Flux comes in two basic formats: liquid and paste. Liquid fluxes are generally used for small, intricate parts. Paste fluxes are generally used for plumbing and piping and other situations that call for larger quantities of flux to be applied to a part before soldering. Paste fluxes are generally applied with a brush.
What is flux in piping?
Flux is part of a dynamic duo of products that allows you to connect copper pipe and fittings by “sweating” or “soldering.” Flux is an acidic paste that comes in a little round tin. … The paste is then applied to the fitting and pipe with a small brush and then the two parts are fitted together.
Why are copper fittings cleaned before soldering or brazing?
It cleans the metal making the solder stick to the fittings and pipe better it cleas oxides and oils. … The longer that copper is kept at the higher brazing temperature, the greater the formation of copper oxide, and nearby valves may be overheated. Why is it important to heat braze joints as quickly as possible?
Why do you solder rings?
Soldering a wedding band to an engagement ring will prevent your rings from sliding around and actually preserve the metal on your rings.
What are end feeds?
End feed fittings are a simple and cost-effective way to join pipework that is made of copper in plumbing systems. Fully recyclable, they will require soldering.
Can you over heat copper?
Overheating is a major problem when brazing or soldering copper pipe because the flux will burn (become oxidized), stop working, and become a barrier to tinning. In addition, a heavy oxide can be formed on the pipe itself, preventing a bond from forming between the filler metal and the pipe surface.
What are capillary fittings?
[′kap·ə‚ler·ē ‚fid·iŋ] (engineering) A pipe fitting having a socket-type end so that when the fitting is soldered to a pipe end, the solder flows by capillarity along the annular space between the pipe exterior and the socket within it, forming a tight fit.
