What is Flareless tube fittings?
A flareless fitting, also referred to as a compression fitting, uses a single ferrule and a nut to make a connection, eliminating the need for flaring. Flareless fittings are common because they can be used with a wide variety of tubing types and because connections are easy to make.
What is an ermeto fitting?
Ermeto-fittings soon became popular due to the simple as- sembly which basically just requires two wrenches. Today, the EO fitting is the most widely used bite-type fitting in the world. EO fittings are designed for metric tube. All threads, hexa- gons, bores and other dimensions are purely metric.
What is a Flareless compression fitting?
Flareless fittings contain a connection with a 3-piece design that contains a Nut, Ferrule (Sleeve), and the Body. Flareless fittings are popular in many applications worldwide due to their reliability and pressure holding capabilities.
How do you identify an fitting?
You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).
How do I know what type of hydraulic fitting I have?
There are six types of threads commonly used on hydraulic tube fittings: UN/UNF. NPT/NPTF. BSPP (BSP, Parallel)…Four Steps to Thread Identification
- Step 1 – Determine if the thread is tapered or parallel.
- Step 2 – Determine the pitch.
- Step 3 – Determine the size.
- Step 4 – Designate the thread.
What is better flare or compression 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.
What is an ED seal?
ED rings are elas- tomeric (soft) seals, which, in conjunction with high-grade connecting elements, assure optimum functional perform- ance even in extreme application conditions.
What is a cutting ring connection?
Cutting ring fittings are flareless fittings used for connections in fluid applications. They are widely used worldwide in hydraulic systems.
What size AN fittings do I have?
How do I know if I have Parker hydraulic fittings?
There are six types of threads commonly used on hydraulic tube fittings: UN/UNF….Four Steps to Thread Identification
- Step 1 – Determine if the thread is tapered or parallel.
- Step 2 – Determine the pitch.
- Step 3 – Determine the size.
- Step 4 – Designate the thread.
Can you connect NPT to FIP?
Most pipe thread types are not interchangeable. NPT, MIP, and FIP work together but do not mate with any other types.
Should I use PTFE tape on compression fittings?
Can I Use PTFE Tape on Compression Fittings? No. PTFE tape is not designed to seal compression fittings and is ineffective at doing so.
How do you read an fitting?
The AN size number is correctly displayed with a dash before the number. Each AN size also references a standard male and female thread size that is used on fittings, such as hose-end fittings, adapters, and port fittings. This is known as “AN Thread Size.” AN fittings have straight thread, and use O-ring seals.
What thread size is an?
“AN” SIZES
