Eisele Basicline: pneumatic couplings for compressed air and vacuum
Basicline is Eisele's standard line: a complete range of pneumatic couplings in brass and nickel-plated brass for compressed air, vacuum and technical gases. It is the basis for virtually every connection task in machine building, from a single cylinder connection to a complete compressed air network.
What sets the line apart from standard pneumatics is the construction. All parts are machined from solid metal, with no stamped or bent parts. You notice this during installation, and especially afterwards: in a compressed air installation, leakage losses add up unnoticed to a substantial part of your compressor costs.
Applications
- Machine and plant construction: cylinder connections, valve terminals, media supply
- Vehicle construction and automation: pneumatics in production lines
- Verpakkingstechniek: compacte pneumatiek in beperkte inbouwruimte
- Process installations: compressed air supply and actuation of fittings
- Maintenance and installation engineering: replacement and extension of existing networks
What you can build with this line
Push-in fittings: tool-free installation by simply inserting the tube. Available in straight, elbow, T, L and Y versions, with release via sleeve or ring depending on the available installation space.
Screw fittings: fixed connections for applications with heavier mechanical loads, or where a larger nominal bore is needed for higher flows.
Quick couplings: connecting and disconnecting under operating conditions, for example for hand tools and temporary connections.
Function fittings: couplings with an integrated function such as throttling, check or venting. A swivel fitting with a throttle check valve saves you a separate component and a connection point.
Bulkheads and manifolds: for feeding lines through a wall or panel and splitting to multiple branches.
Tubing and accessories: matching plastic tubing in different grades, plus blanking plugs and mounting accessories.
Each type is available in a large number of sizes and thread combinations. The complete versions per type can be found in the catalogue.

Frequently asked questions
What is Basicline suitable for?
For compressed air, vacuum and technical gases in industrial applications. For cooling water we recommend Liquidline, for corrosive media Inoxline and for direct food contact Cleanline.
What is the difference between a push-in fitting and a screw fitting?
A push-in fitting is installed without tools by inserting the tube and is intended for fast installation. A screw fitting is tightened and is suitable where the connection is subject to heavier mechanical loads or where a larger nominal bore is needed.
Wat is het verschil tussen ontgrendeling via huls of ring?
Both are ways to release a push-in fitting. The choice depends on the available installation space and your preference for disassembly. With little space around the fitting, one version is more practical than the other; we are happy to advise you on this.
Can I combine Basicline with existing pneumatics?
Ja. The line is available with common G, metric and NPT threaded connections. State which thread types you use in your request and we will check compatibility.
Why brass and not stainless steel as standard?
Brass is sufficient for dry compressed air and is considerably more economical. Stainless steel is needed for corrosive media and environments, and in hygiene-sensitive applications. That is what Inoxline and Cleanline were developed for.
