FormulaMod Anti-Off Hard Tube Fitting G1/4 OD14mm White 4-Pack

Hard-Tube Fitting Kit for Custom Loops

This FormulaMod four-pack supplies anti-off compression fittings built for 14 mm outer-diameter hard tubing in G1/4 threads. White copper bodies with non-slip silicone inserts lock tubing securely without marring the surface. The kit targets builders assembling a custom liquid-cooling loop who need a reliable, leak-resistant joint.

Suits rigid-tube loops; not for soft tubing

These fittings suit rigid acrylic, PETG or glass tubes measuring 14 mm OD and will not seal soft tubing. Installers who prefer push-in or barbed connections for flexible hose should look at a different fitting style. The four-piece count covers a basic CPU-to-radiator run; larger loops will require additional packs.

G1/4 thread with 14 mm OD compression

The single specification that decides fitment is the G1/4 thread paired with a 14 mm outer-diameter compression design. Verify that every block, radiator, pump and reservoir in your loop presents a G1/4 port before purchasing.
