Compression fittings create removable plumbing connections on standard rigid and flexible copper pipe and tubing. They are most commonly found on water shutoff valves, or stop valves, the type used on faucet and toilet water supply pipes.
What fittings work on soft copper?
Flare fittings are the most common connection for underground soft copper joints. Some codes allow a silver solder or sil-phos solder, this requires a much hotter flame to melt, similar to a braze joint.

Compression fittings in the world of plumbing are very common. They are a safe way to connect copper pipe without the use of heat making them popular with DIY’ers. Many different types of valves, tees, connectors and utilities require compression fittings in order to make them water tight and safe.
Why do plumbers hate shark bites?
SharkBites work better than plastic quick-connects on copper pipes because the lead-free brass body is rigid like the pipe and has a higher pressure tolerance. … We don’t recommend using a SharkBite fitting outside because sunlight can dry out the rubber O-ring and cause it to crack or split.
Can I use compression fittings on hard copper?
You were told wrong…you can use brass compression fittings on regular hard drawn copper. Plumbing pipe is sold by the I.D. Example 3/4 copper is 7/8 O.D. They do make 3/4 o.D. copper but its most common is ac and refrigeration work.
What's the difference between hard and soft copper?
Hard copper is rigid line used throughout the house. Soft copper is used where flexibility is needed, such as faucet supply lines.Can you Propress soft copper tubing?
ProPressG is approved for use with hard copper tubing from ½” to 2″ and soft copper tubing in ½” to 1¼” diameters.
Are compression fittings as good as solder?Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.
Article first time published onDo ProPress fittings fail?
It was said that pro-press fittings will not leak unless moved in some manner, and that the failure rate is closer to 0% than 1% in static applications.
Can you use ProPress for compressed air?
Viega ProPress Two-Piece Adapter Flanges Powder coating isolates the dissimilar metals, preventing electrolysis. It is a two-piece design multi-purpose adapter flange for use in general utility, potable water, chilled and hydronic heating water, vacuum and compressed air service as well as in fire protection systems.
Can you ProPress copper to steel?
Viega ProPress and Viega MegaPress fittings have been tested to the strictest standards in North America. Viega ProPress in copper and two grades of stainless steel, 304 and 316, is suitable for nearly any application, from potable water in commercial projects to corrosive chemicals in industrial projects.
When should you use a compression fitting?
Typically, a compression fitting is used to connect copper tubing to the icemaker. To prevent the thin 1/4″ tubing from kinking or bending when the refrigerator is pushed back to the wall, an excess of tubing is normally “coiled” behind the refrigerator.
Do you need jointing compound on compression fittings?
No jointing compound is needed on compression fitings but it is OK to use if it makes you feel better.
Can I use SharkBite on flexible copper?
SharkBite fittings can only be used with hard drawn copper types K, L, and M. … It is not required for copper or CPVC, however, it is not necessary to remove the tube liner from the fitting.
What is soft copper?
Type K, soft copper tubing, remains free from rusting and is highly resistant to corrosion and scale formation. Type K has a heavy wall thickness for underground ser- vices from the water main to the house connection. It is conductive to enable thawing and its flexibility allows it to conform to underground trenching.
Can you over tighten a compression fitting?
You can always tighten it more if you under tightened it, but once you over tighten, you have to get a new ferrule.
What is the life expectancy of a SharkBite fitting?
How long do SharkBite fittings last? SharkBite fittings last a long time. In fact, SharkBite warrants the fittings for 25 years when used with SharkBite tubing.
Are SharkBite fittings as good as solder?
There is a growing group of DIYers who would disagree. These groups of home owners feel SharkBite fittings are just as strong as soldering. A few of the criticisms of SharkBite and other push-fit fittings consist of; initially, push-fit fittings do not have the trustworthiness that soldering has.
Can you use SharkBite behind walls?
Fact: SharkBite fittings are IAPMO tested and approved for behind-the-wall and underground applications. … “Push fit fittings can be used in underground applications and as manufactured joints without access panels.
Is ProPress allowed underground?
Viega ProPress fittings are approved for installations in both above – and below – ground applications. Per code, local inspector approval must be obtained prior to installation below ground.
Can you use pro Press on type M copper?
The propress works fine on Type M copper and up.
What is ProPress G?
The Propress G system is a copper press connection sys- tem designed to meet the demands of natural gas and liq- uid propane gas in the vapour state as well as fuel oil sys- tems. … Propress G utilizes an HNBR sealing element to provide per- manent leak-proof connections in dimensions from DN15 (1/2″) to DN100 (4″).
What makes soft copper soft?
Copper is softened or “annealed” to its soft form by heating it above a critical temperature and allowing it to cool to ambient temperature more slowly.
Is pure copper hard or soft?
Specific Gravity8.89 – 8.94Yield Strength (0.5% Extension)20,000 psi min.Elongation in 2″ – approx.30%Shear Strength25,000 psi
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?
Are copper pipe compression fittings vs solder?
Copper pipes are usually soldered together, a process called sweating, but they can also be joined with compression fittings. The latter have advantages in certain situations and are used exclusively for gas pipes.
Why do my compression fittings leak?
If the pipe gets bent back and forth, the compression fitting could eventually spring a leak. … Over tightening a compression fitting can also cause the fitting to leak. When tightening up the compression fitting, only turn your tool until you feel resistance. From there, you shouldn’t turn it anymore than a half a turn.
Do ProPress fittings leak?
In general, Viega Propress fittings only leak due to one of three reasons; the fitting was never pressed, the copper tubing was not properly inserted or the pressing jaws were not properly aligned. If the fitting was never pressed, confirm that the tubing is properly installed and proceed with pressing.
When did ProPress come out?
The pioneer of press fittings, Viega’s ProPress fittings have provided a strong alternative to traditional connections since their introduction in 1989 and now see over a million installations a day.
