12-pack G1/4 compression fittings for soft tubing

This 12-piece set provides G1/4 threaded compression fittings finished in black chrome over brass. Each fitting accepts 10×16 mm soft tubing with a 3/8 inch inner diameter and 5/8 inch outer diameter. The pack suits builders assembling or extending a custom liquid-cooling loop who need a consistent look across multiple connection points.

Brass construction with embedded O-ring seal

High-quality brass resists corrosion while the integrated O-ring creates a leakproof joint once the compression collar is tightened. The material choice keeps weight low at 0.3 kilograms for the full dozen, and the black chrome exterior maintains a uniform appearance under coolant dyes or UV lighting without adding acoustic or thermal load to the loop.

Direct G1/4 thread fits standard water-block ports

No adapters are required when connecting to components that already expose G1/4 threads, such as radiators, reservoirs, pumps or CPU/GPU blocks. The fittings free up routing flexibility because the 10 mm inner diameter accommodates common PVC hose while the compression design allows tool-free disassembly for loop maintenance or reconfiguration.

Questions about this item

How do I install the G1/4 compression fittings on 3/8" ID soft tubing without stripping the threads?

Slide the compression ring and nut onto the 10×16 mm PVC hose, push the hose fully over the brass barb until it seats against the embedded O-ring, then hand-tighten the knurled nut until firm — avoid tools that can over-torque the G1/4 brass threads.

Which parts will need replacement after extended use in a liquid-cooling loop?

The embedded O-rings supplied in the 12-piece pack are the primary wear items; plan to swap them during annual loop maintenance or if a slow seep appears at the barb.

What is the first limit reached when the loop runs under sustained load?

The brass body and black chrome finish handle continuous coolant temperatures well beyond typical PC loops, so the practical limit is the 10×16 mm PVC hose’s own temperature rating, not the fitting.
