BSPT Push-To-Connect Fittings for Pneumatic Tubing
Pneuforce BSPT push-to-connect fittings are designed for connecting pneumatic tubing to components with British Standard Pipe Taper (BSPT or R) threaded ports. These one-touch pneumatic fittings provide a fast, secure and leak-resistant connection for polyurethane and nylon tubing while allowing repeated installation and removal without damaging the tubing or fitting.
BSPT threaded push-in fittings are commonly used on pneumatic cylinders, valves, vacuum generators, FRL units and industrial automation equipment throughout Europe, Asia and many international markets. They are an excellent choice for OEM machinery and imported equipment that requires BSPT threaded pneumatic connections.

What Is a BSPT Push-To-Connect Fitting?
A BSPT push-to-connect fitting combines a British Standard Pipe Taper threaded connection with a one-touch tube connection for pneumatic tubing. The tapered threaded end screws into a BSPT threaded port while the opposite end accepts pneumatic tubing using an internal gripping mechanism and elastomer seal.
This design allows compressed air tubing to be installed quickly without compression nuts or special tools while providing a dependable connection that can easily be disconnected during maintenance.
What Is BSPT?
BSPT stands for British Standard Pipe Taper and is also referred to as an R thread under ISO 7-1. Unlike BSPP threads, BSPT threads are tapered and create a seal through thread interference, typically assisted by thread sealant or PTFE tape.
Pneuforce BSPT push-in fittings are supplied with factory-applied thread sealant to simplify installation and help provide a secure, leak-resistant threaded connection.
BSPT vs BSPP Threads
Although BSPT and BSPP threads share a similar thread angle, they are designed differently. BSPT threads are tapered and seal through the threads, while BSPP threads are parallel and normally require an O-ring or sealing washer to achieve a pressure-tight seal.
Selecting the correct thread type is essential for reliable pneumatic performance and to prevent thread damage or compressed air leaks.
Common Applications
- Pneumatic Cylinders – Compressed air connections for imported cylinder ports.
- Directional Control Valves – Solenoid valves, manual valves and valve manifolds.
- Vacuum Venturi – Vacuum generators and ejector systems.
- FRL Units – Filters, regulators and lubricators.
- Industrial Automation – Packaging machinery, robotics, assembly equipment and OEM machines.
- Compressed Air Systems – Pneumatic distribution and control circuits using BSPT ports.
Choosing the Correct BSPT Push-In Fitting
Choose the fitting based on tubing outside diameter, BSPT thread size, fitting style, operating pressure and available installation space. Common configurations include straight connectors, elbows, branch tees, bulkhead fittings, reducers, unions and swivel fittings.
For best sealing performance, always tighten BSPT fittings according to the recommended torque and avoid mixing BSPT and BSPP thread types unless specifically designed to do so.
Frequently Asked Questions
What is a BSPT push-to-connect fitting?
A BSPT push-to-connect fitting connects pneumatic tubing to components using British Standard Pipe Taper threads and a one-touch tube connection.
What does BSPT stand for?
BSPT stands for British Standard Pipe Taper and is also referred to as an R thread under ISO 7-1.
How do BSPT threads seal?
BSPT threads are tapered and normally seal through thread interference with the assistance of thread sealant or PTFE tape.
What is the difference between BSPT and BSPP?
BSPT threads are tapered and seal through the threads, while BSPP threads are parallel and typically seal using an O-ring or sealing washer.
Can BSPT push-in fittings be used with vacuum?
Yes. Selected Pneuforce BSPT push-in fittings are suitable for vacuum service up to 29.5" Hg depending on the application.
What tubing is compatible with BSPT push-in fittings?
These fittings are designed for polyurethane and nylon pneumatic tubing in inch outside diameters.
Why do BSPT fittings use pre-applied thread sealant?
The factory-applied thread sealant speeds installation, improves sealing performance and helps reduce the likelihood of compressed air leaks.
Can BSPT fittings be installed into BSPP ports?
Although the thread forms are similar, BSPT and BSPP fittings are designed to seal differently. Always verify the equipment manufacturer's thread specification before installation.
Where are BSPT fittings commonly used?
BSPT fittings are commonly used on imported pneumatic equipment, valves, cylinders, vacuum systems, FRL units, packaging machinery and industrial automation systems.
How do I choose the correct BSPT push-in fitting?
Choose the fitting based on tubing outside diameter, BSPT thread size, fitting style, operating pressure, temperature range and the equipment manufacturer's port specification.
