FormulaMod Hard Tube Fitting 16 mm OD G1/4 8 Pack Black

Fittings for 16 mm hard tube

These compression fittings connect rigid tubing with a 16 mm outer diameter to any component using a standard G1/4 thread. The eight-piece kit supplies enough connections for a typical custom loop. They are built from H59 brass for corrosion resistance and long service life.

Diamond texture for tool-free tightening

The knurled collar lets you secure the tubing by hand without marring the surface. Each fitting seals directly against the hard tube, so no separate clamps or inserts are required. This keeps the loop clean and reduces the number of potential leak points.

Brass construction handles sustained pressure

H59 brass maintains its seal under continuous pump pressure and temperature cycling. The material resists stress relaxation better than softer alloys, so joints stay tight during extended gaming or rendering sessions. Eight fittings provide spares for future loop changes.
