Color Black

  • Copper construction resists corrosion in liquid loops
  • G1/4" thread fits standard water-cooling components
  • Black finish matches dark-themed builds
  • Supports 10x13mm and 10x16mm soft tubing
  • Grain direction may vary between production batches

Compatible Soft-Tube Sizes

The FormulaMod Fm-3FB fitting accepts soft tubing with a 10 mm inner diameter and either a 13 mm or 16 mm outer diameter. It connects to any component that provides a standard G1/4" thread. The copper construction with a black finish suits custom loops where mixed tube wall thicknesses are used.

Thermal and Flow Characteristics

Copper conducts heat efficiently, so the fitting body does not become a thermal bottleneck in the loop. The smooth internal bore adds negligible restriction, keeping pump noise and power draw at the level dictated by the other components. No fans or active cooling are associated with this part.

Behaviour Under Sustained Load

During continuous circulation the fitting remains mechanically stable and maintains its seal at normal loop pressures. The copper material resists deformation and corrosion over long operating periods. Builders who need angled or rotary joints, or who require hard-tube compression fittings, must select different parts.

Questions about this item

How do I install the FormulaMod Fm-3FB fitting onto 10x13mm or 10x16mm soft tubing, and what step is commonly missed?

Slide the compression ring over the tube, push the tube fully onto the barbed end until it seats against the body, then tighten the collar by hand plus a quarter turn with a wrench; the step often missed is confirming the tube sits flush against the internal shoulder before final tightening.

What maintenance or replacement will the FormulaMod Fm-3FB fitting need over time?

Inspect the internal O-ring annually for hardening or flattening; replace the O-ring if any coolant seepage appears at the collar joint, otherwise the copper body and G1/4" threads require no scheduled replacement.

What is the first limit that appears when the FormulaMod Fm-3FB fitting runs under sustained loop pressure and temperature cycles?

The primary limit is the soft tubing itself — prolonged heat and pressure can cause the 10x13mm or 10x16mm tube to harden or creep at the barb, risking seal loss before the copper fitting or G1/4" threads show any fatigue.
