THREAD TYPES
Mastery of standards and precision in connections
BSP Threads (British Standard Pipe)
BSPP Threads: Expertise in BSPP (parallel) connections with sealing via gasket.
BSPT Threads: Expertise in BSPT (tapered) connections with sealing through pre-applied coating within the threads.
NPT & NPTF Threads (National Pipe Threads)
NPT Threads: American tapered threads providing sealing through pre-applied coating (NPT).
NPTF Threads (fuel): For leak-tight sealing through thread deformation, without external sealant.
Metric Threads
Cylindrical ISO standard ensuring international compatibility.
Reliable sealing achieved by a sealing gasket or integrated bonded washer.
THREAD DIMENSIONS
Technical precision at the service of your installations.
Main thread standards
Our fittings are available according to several standards used in industry :
-
Metric threads (M)
European standard, widely used in mechanical assemblies. -
BSPP (G) – Parallel
Parallel thread, often used with a gasket to ensure sealing. -
BSPT (R) – Tapered
Tapered thread providing sealing through progressive tightening. -
NPT – Tapered (American standard)
Widely used in international installations, particularly in instrumentation.
How to identify a thread ?
To determine the correct size, several factors must be considered:
- Outside diameter (D1 / D2)
- Thread pitch (P)
- Type: parallel or tapered
- Standard: metric, BSP or NPT
Recommended tightening torques
Excessive tightening may damage the fitting, while insufficient tightening can cause leaks.
We recommend following standard tightening torques according to:
- thread type
- fitting size
- material used.

Frequently Asked Questions
Here are some common questions about our fittings.
Selecting a pneumatic fitting depends on several key technical criteria:
Key factors to consider:
Thread type: BSP, NPT, metric (must match your system)
Tube diameter: must fit perfectly to ensure sealing
Operating pressure: some fittings are designed for high pressure
Application type: compressed air, vacuum, specific fluids
Environment: temperature, humidity, corrosion
⚠️ Common mistakes:
Choosing incompatible fittings → immediate leaks
Undersizing → flow loss
Wrong material → premature wear
Poor selection can lead to significant energy losses and production downtime.
→ Use our guide or request expert advice to ensure the right choice
There are several types of fittings, each designed for specific applications:
- Quick couplings 👉 Instant connection/disconnection, ideal for maintenance
- Push-in fittings 👉 Widely used in automation, fast tool-free installation
- Threaded fittings 👉 Strong, durable connections for fixed installations
- Stainless steel fittings 👉 Ideal for corrosive or food-grade environments
- High-pressure fittings 👉 Designed for demanding applications
How to choose?
It depends on:
your installation
frequency of use
industrial environment
Each type meets a specific need → making proper selection essential.
Compressed air leaks are a major issue in industry, accounting for up to 20–30% energy losses.
Main causes:
Incorrect or unsuitable fittings
Wear or poor-quality components
Improper installation
Vibrations
✅ Best practices to prevent them:
Choose industrial-grade fittings
Check thread and diameter compatibility
Ensure proper installation (avoid overtightening)
Regularly inspect installations
Use materials suited to the environment
→ Optimize your network with reliable, properly selected fittings
