Flat-bottom fittings

Our main fitting systems

Depending on your pressure requirements and application, you can choose from several patented designs:

1. Super Flangeless™ Fittings (highest performance)

This system offers the highest pressure resistance for flat-bottom ports.

• Torque-free: The ferrule consists of two parts (a polymer cone and a stainless steel locking ring), so the tubing does not rotate while tightening.
• Pressure range: Up to 10,000 psi (690 bar) when using PK material.
• Vibration resistant: Ideal for systems subject to movement or vibration.

2. Flangeless Fittings (the standard)

The most widely used solution for general fluid paths.

• Ease of use: Easy to tighten by hand.
• Pressure range: Typically up to 500 - 2,500 psi (34 - 172 bar), depending on the tubing size.
• Versatile: Available in many colours and materials (ETFE, PEEK, polypropylene).

3. VacuTight™ Fittings

Specially developed for vacuum applications and low pressure.

• Sealing: Prevents "over-compression" and guarantees an airtight connection.
• Application: Ideal for autosamplers and liquid handling robots.
