Compression and Barbed Fittings
Compression Fittings
Compression fittings make a strong, leak-proof connection for pneumatic systems. You use them when you need a tight seal under high pressure. The fitting has two main parts: a ferrule and a nut. When you twist the nut, the ferrule squeezes the pipe. This makes the pipe stay in place and stops leaks.
Ferrule and Nut Design
The ferrule goes between the nut and the pipe.
When you tighten the nut, the ferrule bends a little.
This bending holds the pipe tight and seals the joint.
You get a safe connection that works well with high pressure.
Compression fittings are good when you need something strong and reliable. People use them in factories where pneumatic systems run at high pressure.
Barbed Fittings
Barbed fittings let you connect hoses fast and easy. You push the hose onto the barbed end. The barbs grab the inside of the hose and hold it tight. This design spreads out the pressure and helps stop leaks.
Hose Compatibility
Barbed fittings work best with soft, bendy hoses.
The bumps on the fitting grip the inside of the hose.
You do not need tools to put them on.
These fittings are simple to put on and take off.
Barbed fittings are best for low-pressure jobs. You see them in boats, plumbing, and places with chemicals. The barbs keep the hose from leaking, even if it moves or bends.
Tip: Use barbed fittings for quick fixes or when you change hoses a lot.
Use Cases
Here is a simple chart to compare compression and barbed fittings:
You will see compression fittings in factories, plumbing, and HVAC jobs where leaks are not allowed. Barbed fittings are used in car fuel lines, watering systems, and medical tubes. People also use them on farms and boats.

Threaded Pneumatic Quick Connect Fittings
Threaded pneumatic quick connect fittings give you a safe and dependable way to connect pipes, hoses, and tools. SDH Malleable Iron Pipe Fittings provide strong threaded options that work well in tough environments. You can use these fittings for new setups or repairs.
NPT, BSPT, BSPP Threads
There are three main types of threads in pneumatic quick connect fittings:
NPT (National Pipe Tapered): Used mostly in the U.S. These threads have a 60° angle and are tapered. You need a sealant to stop leaks.
BSPT (British Standard Pipe Tapered): Common in Europe. These threads have a 55° angle and are tapered. Sealant is also needed here.
BSPP (British Standard Pipe Parallel): These threads are straight, not tapered. They use an O-ring to seal, so no extra sealant is needed.
Mixing these thread types can cause leaks or damage. Each type has a different angle and sealing method. Always match the thread type to your system.
Tip: Check your equipment before choosing a thread type. Using the right thread makes a tight, leak-free connection.
