Many customers do not know how to install the compression fittings, in this article , it will introduce how to install the compression fitting :

1. Saw the appropriate length of seamless steel pipe to remove port burrs. The end face of the pipe should be perpendicular to the axis, and the angle tolerance should not be greater than 0.5 degrees. If the pipe needs to be bent, the length of the straight segment from the end face of the pipe to the bend must not be less than three times the length of the nut.

2. Put the nut and ferrule on the seamless tube, pay attention to the direction of the nut and ferrule, and do not install it in reverse.

3. Apply lubricating oil to the threads and ferrules of the pre-assembled fitting body, insert the pipe into the fitting body, the pipe must be inserted to the end, and tighten the nut by hand.

4. Tighten the nut until the ferrule jams the tube, this turning point can be felt by the increase in tightening torque.

5. After reaching the pressure point, tighten the hold-down nut for 1/2 turn.

6. Remove the pre-assembled fitting body and check the insertion of the ferrule edge, the visible protrusion band must fill the space on the ferrule endface. The ferrule can be rotated slightly, but not axially.

7. For final installation, lubricate the joint body and threads in the actual installation, and tighten the compression nut with it until the tightening force can be felt, and then tighten it for 1/2 turn to complete the installation.

Thread difference between BSPT, BSPP & NPT

Different thread sealing depending on the geographical region,size of the pressure system and the environment. Fox example, In Asia, such as China, Korea, Japan etc normally use BSPT; In U.S, Canada etc always use NPT, then for BSPP thread most popular in UK, Europe, Australia, New Zealand and South Africa. While one sealing style is not inherently better than another each style has its application.

NPT Connections ( National Pipe Thread)- US & Canada



It is according to ANSI/ASME B1.20.1 Pipe Threads. 60 degree of thread angle. NPT male adapters have a taper thread that wedges into the female NPT adapter.



BSPT Connections (British Standard Pipe Taper)- China, Korea, Japan

BSPT thread is similar to NPT except for one important difference. The angle across the flanks of threads is 55 degrees instead of 60 degree as it is for NPT thread. Thus an NPT male thread could fit into BSPT female thread, but couldn’t sealing.



BSPP Connections ( British Standard Pipe Parallel)- UK, Europe, Australia,South Africa

BSPP thread is also British standard. It is a parallel thread fitting that uses a bonded seal ring to do the sealing. For historical reasons, BSPP has other different names at the same time. Such as BSPF ( British standard pipe fitting), BSPM(British Standard Pipe Mechanical) and PS (British Standard Pipe Straight) and so on.



For our thread valves & thread fittings, thread standard always most important for manufacture.

So please pay more attention about these difference.

BSPT & BSPP both referred to as BSP, so most of our customer maybe only told you needs BSP thread. Normally for female thread, 99% is BSPP. For male thread, BSPT & BSPP, 50%.

(1) BSPP male thread could 100% connected with BSPP female thread,but NOT MATCH BSPT Female Thread



(2) BSPT male thread couldn't 100% connected with BSPP female thread, needs using PTFE tap.

Introduction: Compression fittings are a popular choice for connecting pipes and tubing in plumbing and various industrial applications due to their ease of use and reliability. Whether you’re working on a plumbing project at home or maintaining industrial piping, knowing how to properly install and maintain compression fittings is crucial. Here’s a comprehensive guide to help you get the job done right.

Section 1: Understanding Compression Fittings

Before diving into the installation process, it’s important to understand what compression fittings are and how they work.


Definition: Compression fittings are used to connect two tubes or pipes together without the need for soldering, threading, or welding.
Components: They typically consist of a compression nut, a compression ring (also known as a ferrule), and a sleeve.
Materials: Available in various materials such as brass, copper, stainless steel, and plastic, each suited for different types of applications.

Section 2: Installation Tips for Compression Fittings

Follow these steps to ensure a successful installation:


Gather the Right Tools: You’ll need a pipe cutter or hacksaw, a reamer or deburring tool, a wrench, and possibly some pipe lubricant.
Cutting the Pipe: Cut the pipe to the desired length using a pipe cutter for a cleaner cut or a hacksaw for quicker work. Always ensure a straight cut.
Deburring: Remove any burrs from the inside and outside of the pipe end to ensure a smooth fit.
Prepare the Fitting: Slide the compression ring (ferrule) onto the pipe, followed by the sleeve.
Insert the Pipe: Insert the prepared pipe into the fitting, making sure the ferrule and sleeve are aligned with the threads on the fitting.
Tighten the Nut: Hand-tighten the compression nut onto the fitting, then give it an additional quarter-turn with the wrench. Be careful not to over-tighten, as this can damage the fitting.
Check for Leaks: Once installed, turn on the water supply or apply pressure to the system and check for leaks.

Section 3: Maintenance Recommendations

To ensure the longevity of your compression fittings, follow these maintenance tips:


Regular Inspections: Check for any signs of wear, corrosion, or leaks periodically.
Lubrication: Apply a small amount of pipe lubricant to the threads before installation to ease nut tightening and future disassembly.
Avoid Over-Tightening: Over-tightening can cause the ferrule to crack or the sleeve to deform, leading to leaks.
Temperature Considerations: Be aware of the temperature limits of the materials used in your compression fittings to prevent failure.
Replacement: If you notice any damage or signs of wear, replace the fitting immediately to prevent system failure.

Conclusion: Proper installation and regular maintenance of compression fittings are essential for a reliable and leak-free piping system. By following the tips outlined in this guide, you can ensure that your compression fittings perform optimally and last for years to come.
