compression fitting sizes

The threads on compression fittings are usually 1/2″ BSP and 3/4″ BSP (for the 15mm and 22mm fittings).

What thread is on a 3/8 compression fitting?

Compression 3/8 Tubing OD to UNEF Thread 9/16-24 Male Fitting Straight.

How is BSP measured?

How to Measure Your BSP Fittings
Measure the outer diameter (OD) of the thread (in inches)Then subtract 25% from this (¼ inch) You’ll then need to make sure it is a BSP fitting so by counting the threads on your coupling, perhaps only just over ¼”, you can just multiply this by four to find the threads per inch.

Is pipe measured ID or OD?

In short: Tube is measured by outside diameter, pipe is measured by inside diameter. There is often confusion as to which size die the customer actually needs – Pipe Size or Tubing Size. Keep in mind that pipe size refers to a nominal – not actual – inside pipe diameter. Schedule refers to the pipe’s wall thickness.

How big is a 15mm compression nut?

That is correct. The nut size (dimension across the flats) are 24 mm and 32 mm for the 15 and 22 mm compression fittings respectively.

What size is the nut on a 3/8 compression fitting?

Nut, 3/8 in Tube Size, Metal, 11/16 in Hex Size.

What thread is 1/2 compression fitting?

1/2″ Compression Fitting by 1/2″ Female NPT Thread. 1/2″ Compression Fitting by 1/4″ Male Elbow.

Are compression fittings OD or ID?

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”.

How do you measure compression thread size?

Measure the Outside Diameter (OD) of your pipe or pipe fitting: Wrap a string around the pipe. Mark the point where the string touches together. Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference) Divide the circumference by 3.14159.

What thread size is 15mm isolation?

The 15mm Isolating Valve fits 3/8” tail and is compatible with stainless steel, plastic and low carbon steel pipes. It’s a compression fitting with one 15mm connection for the copper pipe, and a 3/8″ male thread on the other end, suitable for hansgrohe and Grohe taps.

Is half inch pipe same as 15mm?

1/2″ pipe refers to the internal diameter, 15mm pipe is the external diameter In my experience they are so similar that you can even use solder fittings without a worry, so using 15mm olives on 12″ pipe isn’t a problem. Occasionally they are very marginally tight, but not enough to be an issue.

What thread is a 10mm compression fitting?

The 10mm compression end you fit on to a 10mm pipe, and the ¼” BSP thread is attached to to a female connection.

What is BSP size?

Minor diameter is the measurement of the inside of a female threaded connection, from thread to thread. BSP Size. Also Known As. Actual Diameter (Imperial) Actual Diameter (Metric)

What size is a BSP thread?

Measure the Inside of a Female Thread Port:

If it is 19.1mm Internal Diameter — then the actual port size is a Female 1/2″ BSP Thread. If it is 24.6mm Internal Diameter — then the actual port size is a Female 3/4″ BSP Thread. If it is 31.0mm Internal Diameter — then the actual port size is a Female 1″ BSP Thread.

Is 3/4 BSP the same as 22mm?

If your ball valve is 22mm it is a copper compression fitting otherwise all screw threads in the UK even on 22mm metric fittings have 3/4 BSP threads.
