Compatible 12mm Rigid Tubing

This Bykski rigid fitting is designed for 12mm outside diameter tubing made from PETG, acrylic or metal. It provides a secure connection to any G 1/4 threaded port in a custom liquid-cooling loop. The purple finish adds a distinct colour accent to the build.

Builders Using 12mm Hard Tube

The fitting suits enthusiasts assembling a custom loop with 12mm OD rigid tubing who need a reliable G 1/4 connection. It is not intended for users working with soft tubing, smaller or larger diameter rigid tube, or thread standards other than G 1/4.

G 1/4 Thread Interface

The single specification that determines compatibility is the G 1/4 thread, which must match the port on the water block, radiator, reservoir or pump. The fitting accepts only 12mm outside diameter rigid tubing.

Questions about this item

Will the G 1/4 thread on the 12mm OD fitting leak after the loop runs hot all day?

The compression design seals against 12mm rigid tubing and standard G 1/4 ports, so normal operating temperatures will not break the seal.

Do I need to buy 12mm rigid tubing separately for this fitting to work?

Yes, the fitting only accepts 12mm outside-diameter PETG, acrylic or metal tube, which must be purchased separately.

Can I mix this purple fitting with older nickel-plated G 1/4 blocks in the same loop?

The G 1/4 thread is universal, so it will screw into any standard port regardless of finish or age.
