What is OD in compression fittings?
Correspondingly, what is OD compression? Compression ends are made for a tube which has a specific outside diameter (OD). For example, a ¼” compression fitting is designed to connect a section of tubing which has an OD of ¼”. are compression fittings better than shark bites?
What is a compression fittings?
Compression fittings are one of the quickest and easiest ways to join two lines. These connections are typically used on hard copper pipe and soft tubing that has a 3/8" or smaller outside diameter (like faucets and icemakers).
What does od stand for in eye care?
When OD is written next to your eye doctor’s name, it is the professional abbreviation for Doctor of Optometry. There are many abbreviations used in eye care, and sometimes it can be difficult to interpret what they all mean.
What size compression fitting do I need for od pipe?
Compression fittings are sized according to that outside diameter: a 1/2" OD pipe would require a 1/2" compression fitting. A sleeve ("ferrule") is placed over the pipe (use a plastic sleeve for plastic tubing), which is placed inside the fitting.
What are the two types of compression fittings?
There are two types of compression fitting, standard (British type-A/non-manipulative) and flare fittings (British type-B/manipulative). Standard fittings require no modifications to the tubing.

What is the difference between FIP and compression?
MIP or FIP (male or female iron pipe): Same thread dimensions as NPT. BSP(T) or BSP(S) (British standard pipe tapered or straight): Most common in Europe. Compression: A unique threaded fitting that does not mate with other thread types.
Is compression thread same as NPT?
NPT or IPT pipe threads are tapered, Compression Fitting Threads are Parallel. Our illustration, adapted from Industrial Specialties Mfg., shows the key difference between tapered threads cut onto standard pipe fittings (NPT or IPT) and parallel-threads cut onto flare or compression fittings (IPT).
Are plumbing fittings ID or OD?
In our industry, pipes and tubing are sized in two ways: By the outer diameter (OD) for smaller fittings measuring 1/4, 3/8, or 1/2 inch. By the inner diameter (ID). The ID size is referred to as CTS, which stands for copper tube size.

What does FIP and MIP mean?
FIP means Female Iron Pipe. MIP is Male Iron Pipe. As the Pure Water Gazette points out, sometimes FIP is called FPT or Female Pipe Thread. And MIP is called MPT or Male Pipe Thread.
How do I know if I have a compression fitting?
Usually, the ferrule inside a fitting will not give you any means of identification. It is much more common to find markings on the nut of the fitting or at the body. This will include a cast code to enable material traceability.
What are the three types of plumbing connections?
Tee, Wye, Cross and Elbow Fittings You often see tee fittings connected to potable water supply lines. A wye is shaped like a “Y” with the two inlets coming together at roughly 45-degrees into a single outlet in drain applications.
What thread is a 1/2 compression fitting?
Female NPT Thread1/2" Compression Fitting by 1/2" Female NPT Thread.
Can you reuse compression ferrule?
Ferrule can never be reused once they have been compressed. This connector is directly placed over the pipe and the nut is tightened compressing the ferrule between the pipe and the body of the fitting. Flare less-tube connectors can not be reused because of the characteristic nature of the process.

What is compression fitting?
Compression fittings are not as robust as soldered fittings. They are typically used in applications where the fitting will not be disturbed and not subjected to flexing or bending. A soldered joint is highly tolerant of flexing and bending (such as when pipes knock or shake from sudden pressure changes). Compression fittings are much more sensitive to these type of dynamic stresses. They are also bulkier, and may be considered less aesthetically pleasing than a neatly soldered joint. Compression fittings work best when tightened once and not disturbed. Some compression connectors may never be reused, such as a ferrule ring type. It can never be reused once they have been compressed. This connector is directly placed over the pipe and the nut is tightened compressing the ferrule between the pipe and the body of the fitting. Compression of this ferrule also results in deformation of the copper tubing. If a compression type connection needs to be redone, more often than not the compressed copper/ferrule would need to be cut off and a new ferrule is to be used on a clean non-compressed piece of pipe end. This is to assure a leak proof sound connection.
How is the integrity of compression fitting determined?
The integrity of the compression fitting is determined by the ferrule, which is easily prone to damage. Thus care should be taken to when handling and tightening the fitting, although if the ferrule is damaged it is easily replaced.
Why is my compression fitting leaking?
It is critical to avoid over-tightening the nut or else the integrity of the compression fitting will be compromised by the excessive force. 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.
What are the two types of compression fittings?
Types of fittings. There are two types of compression fitting, standard (British type-A/non-manipulative) and flare fittings (British type-B/manipulative). A Push-in compression fitting. Standard fittings require no modifications to the tubing. Flare fittings require modification of the tubing with a special tool.
Do compression fittings need thread sealants?
Thread sealants such as joint compound ( pipe dope or thread seal tape such as PTFE tape) are unnecessary on compression fitting threads, as it is not the thread that seals the joint but rather the compression of the ferrule between the nut and pipe.
Can compression connectors be reused?
Compression fittings work best when tightened once and not disturbed. Some compression connectors may never be reused, such as a ferrule ring type. It can never be reused once they have been compressed.

Overview
A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connection. Compression fittings for attaching tubing (piping) commonly have
How they work
In small sizes, the compression fitting is composed of an outer compression nut and an inner compression ring or ferrule (sometimes referred to as an "olive") that is typically made of brass or copper or steel. Ferrules vary in shape and material but are most commonly in the shape of a ring with beveled edges. To work properly, the ferrule must be oriented correctly, in the case of copper olives they are normally barrel shaped and this means they cannot be fitted incorrectly, but wher…
Types of fittings
There are two types of compression fitting, standard (British type-A/non-manipulative) and flare fittings (British type-B/manipulative). Standard fittings require no modifications to the tubing. Flare fittings require modification of the tubing with a special tool. Standard fittings are typically used for water, hydraulic and compressed air connections, whereas flare fittings are used for gas and high pressure lines.
Advantages
Compression fittings are popular because they do not require soldering, so they are comparatively quick and easy to use. They require no special tools or skills to operate. They work at higher pressures and with toxic gases. Compression fittings are especially useful in installations that may require occasional disassembly or partial removal for maintenance etc., since these joints can be broken and remade without affecting the integrity of the joint. They are also used in situa…
