Eiszapfen 16mm G1/4 HardTube Fitting Sixpack

This pack contains six compression fittings designed for 16mm outer-diameter hard tubing. Each fitting features a G1/4 inch male thread on one end and a knurled nut for secure tube retention. The deep black finish uses a special coating process that resists chipping and peeling. Coloured O-rings are included for customisation.

Suits custom-loop builders using 16mm hard tube

These fittings suit builders assembling a custom water-cooling loop with 16mm rigid tubing and G1/4 threaded components. The knurled nuts allow tool-free tightening while the slanted corners press the O-ring firmly against the tube for transport safety. Buyers needing fittings for soft tubing, different tube diameters, or alternative thread sizes should look at other products.

16mm hard-tube compatibility with G1/4 thread

The decisive specification is the 16mm hard-tube socket paired with a G1/4 inch male thread. This exact combination determines whether the fitting matches your tubing and component ports. Verify both measurements before purchase to ensure a correct fit.

Questions about this item

Should I pick the 16 mm Deep Black sixpack or another finish for my hard-tube loop?

Choose the Deep Black sixpack when you want a durable matte-black look; the special coating process resists chipping and the coloured O-rings let you add accent colours or UV glow.

What does the G1/4" thread mean once the fitting is installed in my loop?

The G1/4" external thread screws into any standard water-block, radiator or reservoir port, giving a universal connection point for 16 mm hard tubing.

How does the compression design with knurled nuts seal 16 mm hard tube in practice?

The slanted nut corners press the O-ring firmly against the tube OD, creating a secure, high-flow seal that holds under vibration and transport.
