How much pressure can a brass compression fitting hold?
Maximum working pressure is 400 psi. Nominal working pressure is 200 psi. -65˚ to +250˚F. used with all part numbers to designate tube and pipe fractional sizes.
What PSI are compression fittings good for?
Compression fittings are used for low-pressure applications, typically ranging from -5 psi to 125 psi.
What are pneumatic compression fittings?
Pneumatic fittings are parts used to connect sections of pipe, tube, and hose in pneumatic (pressurized gas) systems. Compared to hydraulic fittings, pneumatic fittings are typically characterized by tighter seals and lower pressure requirements.
What are brass compression fittings used for?
Compression fittings are built from three pieces, creating a mechanical joint connection fitting which is widely used in plumbing systems to join tubing together.
Are brass compression fittings reliable?
The answer is very simple; compression fittings are extremely reliable! These fittings are a safe choice because they are leakproof and can be used in many types of high-pressure situations.
What is the most common cause of leaking compression fittings?
If the nut is overtightened the ferrule will deform improperly causing the joint to fail. Indeed, overtightening is the most common cause of leaks in compression fittings.
How do I choose a pneumatic fitting?
How to choose the correct pneumatic fitting
- Tubing type needed ( Inch or Metric, Thermoplastic or Metal, Size)
- Air pressure or P.S.I.
- Thread type of fitting needed (pipe, British pipe, metric, SAE Straight Thread)
- Vibration concerns.
- Fitting material needed (brass, stainless steel, thermoplastic, nickel plated brass)

Will compression fittings leak over time?
Compression fittings used on copper pipe are easy to fit together and remove. They are often used to connect fixtures and appliances that will eventually need to be replaced. While compression fittings are convenient, they may leak if not installed correctly.
How do I stop my compression fitting from leaking?

Should I use Teflon tape on a compression fitting?
“Should I use PTFE thread sealing tape or pipe joint compound on my compression threads?” A. No, you definitely should not. 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.
What are pneumatic fittings called?
Pneumatic push-in fittings, also known as push fittings, are the standard on the pneumatic fittings market and are the most widely used. They are characterized by the easy release function for the tube, i.e. by actuating a releasing ring. These compressed air connectors are used with the standard O.D.
Can you use hydraulic fittings for air?
We find it surprising that some mechanics use hydraulic hose for air brake applications. Perhaps they figure that since hydraulic hose is rated at a much higher pressure than air brake hose it is safe to use.
What is the most common air compressor fitting size?
Most standard air compressors require a plug with a 1/2-inch or 1/4-inch flow size, with the latter being more common.
Should I use plumbers tape on a compression fitting?
Also, do not use too much Teflon tape as this could be counterproductive and prevent the joint from sealing properly and/or causing the tape to gum up. DO NOT use Teflon tape under the compression nut or on flare threads of brass compression fittings (or a compression fitting of any other material)!
Should I use thread sealant on compression fittings?
Should you use Teflon tape on a compression fitting?
The bolts need to be tightened. Joint compound and thread seal tape are not necessary on compression fitting threads as they are not the thread that seals the joint but rather the compression of the ferrule between the nut and pipe.
Can I over tighten a compression fitting?
Though valve breakage is a rare occurrence, never underestimate a poorly trained installer with a big wrench. This is a threaded needle valve that was severely over-tightened. Unfortunately, if a compression valve or fitting has sustained this kind of damage from over-tightening, you should replace it.
Why do my compression fittings 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. By doing this, you can ensure you’ll prevent your compression fitting from leaking.
What does ARO mean in air fittings?
Automatic Semi-Universal Interchange Profile
One thick stripe and one thin stripe on body of fitting. Semi-Automatic. Semi-Universal Interchange Profile (ARO, Automotive, Industrial) not applicable. Three thin stripes on body of fitting.
What does JIC mean in hydraulics?
Joint Industry Council
JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel. JIC Fitting hydraulic connections are common in most fluid power systems.
Should I use Teflon tape on air compressor fittings?
The Proper Method to Apply PTFE Tape to Compressed Air Fittings
Are there different size air compressor fittings?
There are many different types of air fittings but most air tools use one of just a few types of connector. The main things to consider are the fitting type and the thread size. Common fixing types include ¼” BSP, ¼” PCL and 3/8” NPT.
Should you use Teflon tape on brass compression fittings?
Also known generically as PTFE tape, it’s generally used as a sealant and lubricating material, perfect for installing fittings in the kitchen and bathroom. In fact, it’s essential to use thread tape for those household brass fittings unless a rubber seal or gasket is in place.
