What do the thread sizes like '1/4 BSPT' actually mean?

The sizes like 1/8, 1/4, and 1/2 refer to the British Standard Pipe Taper (BSPT) thread on the male end. You'll need to match this to the female thread on your valve or manifold. The other end is a quick-release connector for your air tube.

What's the maximum pressure these fittings can handle?

These fittings are rated for a maximum working pressure of 850 kPa (about 8.5 bar). They are made from 304 stainless steel, so they're well-suited for most standard workshop pneumatic systems.

What kind of air line tubing works with these push-fit connectors?

These are designed for standard semi-rigid pneumatic tubing like polyurethane (PU) or nylon. You just push the tube firmly into the connector to get a secure seal. Check your tube's outer diameter matches the fitting size you're ordering.

This stainless steel air hose fitting makes a tight, leak-free connection for your pneumatic tubing. Its push-to-connect design means you can install and remove air lines quickly without tools. These fittings are made from 304 stainless steel, so they are a good choice for systems that need to be clean. Features and Benefits - Push-to-Connect Design - You can connect and disconnect polyurethane or nylon tubing with one push. This speeds up assembly and maintenance. - 304 Stainless Steel Body - This material is much stronger and more corrosion resistant than plastic or brass fittings. It works well in food-grade and washdown settings. - High Pressure Rating - It safely handles working pressures up to 1.0 MPa (145 PSI) and temperatures from -20°C to 120°C. - BSPT Tapered Threads - The British Standard Pipe Taper threads create a secure, mechanical seal when screwed into a matching port. Applications - Food and Pharmaceutical: Use these to connect pneumatic actuators and sensors on equipment that needs sanitary, corrosion resistant stainless steel pneumatic fittings. - Chemical Processing: Build or fix control systems in areas with corrosive fumes or occasional chemical splashes. - Automation and Robotics: This is a solid choice for building end-of-arm tooling and pneumatic systems that need quick-connect air line fittings.
