Precision Fittings for 10x13mm Soft Tubing

These FormulaMod G1/4" compression fittings are built for custom liquid-cooling loops that use 10x13mm (3/8" ID x 1/2" OD) soft tube. The 8-pack supplies enough connectors for a typical CPU and GPU block arrangement. Each piece is machined from H59 brass for corrosion resistance and long-term sealing reliability. The diamond-textured knurl improves grip during hand tightening.

Leak-Free Sealing Under Normal Pressure

The compression design creates a secure seal around the tube wall without requiring clamps or adhesives. H59 brass construction resists coolant additives and prevents galvanic corrosion in mixed-metal loops. Normal operating pressures in desktop cooling are contained with no weeping or drips. The G1/4" thread mates with standard water blocks, radiators, reservoirs and pumps.

Consistent Performance During Extended Operation

Sustained pump pressure and temperature cycles do not degrade the compression seal once the fitting is seated. Brass thermal mass equalises quickly with coolant temperature, avoiding stress on the tube interface. The anti-slip texture ensures the collar remains tight even after months of vibration from pump harmonics. Builders who need angled rotary adapters or larger tube diameters will require different fittings.

Questions about this item

How do I install the G1/4" compression fittings on 10x13mm soft tube, and what step is often missed?

Slide the compression ring onto the tube, push the tube fully over the barb until it seats against the body, then tighten the knurled collar by hand plus a quarter turn with pliers; the step often missed is fully seating the tube before tightening.

What maintenance or replacement will these H59 brass fittings need over time?

Inspect the internal O-rings annually for hardening or cracking; replace any O-ring that shows wear to prevent slow leaks, the brass body itself does not require replacement.

What is the first limit that appears when these fittings run under sustained pressure and temperature?

The EPDM O-ring seal reaches its temperature limit before the H59 brass body, so prolonged high coolant temperatures will degrade the seal first.
