Six-pack G1/4″ fittings for 14 mm hard tubing
This set of six black compression fittings connects 14 mm outer-diameter rigid tubing to standard G1/4″ BSP ports in a custom liquid-cooling loop. The pack covers a typical CPU-and-GPU build or a single-radiator loop without needing extra packs. Builders using acrylic, PETG, copper, brass or stainless-steel tube can use the same fittings throughout.
Replaces mismatched or worn single fittings
Swapping a mixed-brand assortment for a uniform six-pack removes thread-length inconsistencies that can cause weeping at the block or radiator. The upgrade is worth it when you are assembling a new loop or re-tubing an existing one and want every joint to share the same 4.5 mm male thread engagement and 22 mm body diameter.
Hand-tight assembly with an optional spanner flat
Push the tube into the fitting until it seats, then tighten the compression nut by hand and add a quarter-turn with a 22 mm spanner for a leak-free seal. The most common issue is cutting the tube end unevenly, which prevents the internal O-ring from seating evenly; a clean, square cut and a quick chamfer eliminate that problem.

Questions about this item
What clearance does the 22 mm outer diameter of these fittings need inside the case?
The fitting body measures 22 mm across, so allow at least that much space around each G1/4" port for the compression nut to seat without hitting adjacent components.
How far should the G1/4" thread be screwed in before tightening the compression nut, given the 4.5 mm male thread length?
Thread the fitting in until the 4.5 mm male portion is fully engaged, then hand-tighten the compression nut; over-tightening the body instead of the nut is the common error that can strip the port.
When should the internal O-ring be inspected or replaced on a fitting with a 17 mm installed height?
Check the O-ring during any loop drain or if you see seepage at the 17 mm installed joint; replace it if it feels brittle, flattened, or shows cracks.
