Transparent PTFE tubing coil, 4mm OD 2.5mm ID 100ft

MERCURY

MERCURY PTFE Tubing 4mm OD 2.5mm ID 100ft Trap

SKU CH-S2QC-DCBC7

PTFE tubing with 4mm outer diameter and 2.5mm inner diameter supplied in a 100ft length

  • ColorTransparent
  • PTFE material resists chemicals and high temperatures
  • 4 mm outer diameter fits standard push-fit fittings
  • 5 mm inner diameter maintains smooth fluid flow
  • 100 ft continuous length reduces joints and leak points
  • Transparent wall allows visual inspection of flow

PTFE Tubing for Fluid Transfer

Mercury PTFE tubing is supplied in a 100 foot length with a 4 millimetre outside diameter and a 2.5 millimetre inside diameter. The transparent PTFE material resists chemicals and high temperatures while remaining flexible. It is designed for routing fluids in automotive, laboratory or industrial systems where clean, non‑reactive lines are required.

Suited for Precision Routing, Not High‑Volume Flow

This tubing suits builders who need a small‑bore line for instrumentation, coolant loops or pneumatic control circuits. The 2.5 millimetre bore limits volumetric flow, so it is not intended for main fuel supply, hydraulic pressure lines or any circuit that demands a larger internal passage. Buyers needing higher throughput should select tubing with a wider bore.

Critical Specification Is the 2.5 Millimetre

The 2.5 millimetre ID determines whether fittings, flow rates and pressure ratings match the application. Verify that connectors are sized for 4 millimetre OD and 2.5 millimetre ID before ordering. This single dimension governs compatibility with the rest of the fluid circuit.

Questions about this item

How does the 4 mm outer diameter and 2.5 mm inner diameter affect flow in a real plumbing setup?

The 4 mm outer diameter and 2.5 mm inner diameter provide a consistent bore for fluid transfer, suitable for low-pressure lines and precise routing in tight spaces.

What standard does the PTFE tubing follow, and what pressure or temperature does that limit in practice?

PTFE material resists chemicals and handles a wide temperature range, but specific pressure ratings depend on wall thickness and installation method rather than a single published standard.

What does the 100 ft length mean for cutting and fitting the tubing into an existing drain system?

The 100 ft roll allows you to cut exact lengths needed for each run, reducing joints and potential leak points when integrating with compression fittings or barbed connectors.
