Two-ferrule design — front ferrule creates the seal, back ferrule creates the grip — providing dual leak protection and superior vibration resistance. Dimensionally compatible with Swagelok® standard connections. The most widely specified fitting in high-integrity instrumentation service.

One ferrule performs both the grip and seal functions simultaneously. Simpler design with fewer components — easier to assemble and well suited to general instrumentation and process service. Dimensionally compatible with Parker® A-LOK® connections.

Standardised under ISO 8434-1, the cutting ring bites into the tube OD creating a positive grip and metal-to-metal seal. Available in L series (up to 250 bar), S series (up to 400 bar), and LL series for metric tube OD 4 mm to 42 mm. Widely used in European and Middle Eastern hydraulic and industrial projects.

Straight tube-to-tube connection with the same OD at both ends. The most commonly used tube fitting configuration in instrumentation impulse lines, sample systems, and process control tubing networks. Available in both double and single ferrule designs.

Tube compression end on one side and male NPT, BSPT, or BSPP threaded end on the other — used to connect instrumentation tubing to valves, transmitters, gauges, and other threaded process equipment. Available in all tube OD sizes and thread forms.

Tube compression end on one side and female NPT or BSPP threaded end on the other. Used for panel-mount instrument connections and tube-to-female-port adapters in control systems and hydraulic assemblies.

90° tube-to-tube elbow with the same OD at both ends. Used to change the direction of the tubing run without welding. Available as double ferrule, single ferrule, and DIN 2353 bite type in all standard metric and imperial tube OD sizes.

T-shaped tube fitting with all three ends accepting the same tube OD compression connection. Used to branch a tubing run for sample taps, bypass lines, or secondary instrument connections. Available in equal and reducing patterns in double and single ferrule designs.

Passes a tube connection through a panel, enclosure wall, or bulkhead. Secured with a locknut, the bulkhead union allows tubing to enter or exit an instrument enclosure, junction box, or analyser shelter without additional penetration fittings.

The tube end is mechanically expanded to a 37° (SAE J514 / JIC standard) or 45° cone angle creating a metal-to-metal cone-to-cone seal when the nut is tightened. Widely used in refrigeration, hydraulic, and high-pressure pneumatic systems where frequent disassembly is required.

Tool-free tube insertion — an internal collet with radially arranged teeth grips the tube OD on push-in and releases when the collet ring is pressed. Designed for pneumatic control systems, compressed air distribution, and low-pressure water lines. Suitable for PU, PE, PA, and PTFE tubing.

Connects two tubes of different OD sizes — used where tubing size changes in an instrumentation or process system. Also available as male/female reducing adapters in NPT and BSP thread combinations. Essential for mixed-size tubing systems and manifold connections.
