Connector with M10 Thread for 4 mm PTFE Tube, OEM (MPN: AMS-18954)

Threaded connector with M10 external thread designed for use with 4 mm PTFE (Teflon) tubing. This connector provides a secure mechanical coupling for PTFE lines where chemical resistance, low friction and dimensional stability are required. It is intended for installation in fluid or gas systems and is compatible with standard 4 mm outside-diameter PTFE tubing used in laboratory, instrumentation, pneumatic and extrusion equipment.

Advantages

The connector offers a reliable threaded connection using an M10 external thread that ensures firm mechanical retention without deforming PTFE tubing. Constructed to provide corrosion-resistant performance and low friction contact with the tube, the design minimizes leakage risk when installed correctly. Its compact form factor allows integration into confined assemblies and facilitates straightforward replacement or maintenance.

Suitable for

• Laboratory fluid or gas lines using 4 mm PTFE tubing
• Analytical instrumentation and sampling systems
• Pneumatic circuits where chemical resistance is required
• Polymer extrusion or filament feeding setups requiring PTFE guides

Key specifications

• Thread type: external M10
• Compatible tubing outer diameter: 4 mm PTFE (Teflon)
• Intended media: neutral gases and many liquids compatible with PTFE
• Typical applications: fluid transfer, gas lines, instrumentation, pneumatic fittings
• Physical attributes: compact, threaded mechanical coupling for through-panel or inline mounting

How to use

Prepare the PTFE tube by cutting the end square and free of burrs to ensure full contact and sealing. Thread the connector into the mating component with the M10 external thread until hand-tight, then apply appropriate torque if specified by the system designer or installer to achieve a secure fit without over-tightening. Insert the 4 mm PTFE tube into the connector until it seats fully. Verify alignment and perform a leak check at working pressure with the intended media before commissioning.

Usage recommendations

For reliable performance, use PTFE tubing of consistent 4 mm outer diameter and standard wall thickness. Avoid excessive torque when installing threaded connections; follow system-specific torque guidelines. Where vibration or thermal cycling is expected, perform periodic inspections and leak testing. Do not use the connector with media that degrade PTFE or exceed the temperature/pressure limits of the tubing and connected equipment.
