Water-Cooling Compression Fitting

This Bitspower compression fitting connects soft tubing to water-blocks or radiators in a custom liquid-cooling loop. The 90-degree dual-rotary design lets the elbow swivel freely so tubing runs stay clean and kink-free. It suits builders who want a secure, leak-resistant joint without forcing tight bends in limited chassis space. The black sparkle finish matches dark-themed builds while the brass body resists corrosion over long service life.

90-Degree Dual Rotary Geometry

The fitting accepts tubing with a 3/8" inner diameter and 5/8" outer diameter and mates to any component with a G1/4" thread. Its dual-rotary joint allows the elbow to orient in any direction after the base is tightened, eliminating stress on the tube and the block port. The hidden O-ring design seals against the tube wall and the port face simultaneously, reducing the chance of weep leaks that can appear with exposed rings. Thread engagement is 5 mm deep.

Simple Hand-Tight Installation

Push the tubing over the barbed end until it seats against the internal stop, then slide the compression collar down and hand-tighten; no special tools are required. The dual-rotary base can be aligned before the final quarter-turn that locks the orientation. Common issues are tubing cut at an angle, which prevents the collar from seating evenly, and forgetting to lubricate the hidden O-rings with a drop of coolant, which can cause the ring to roll during tightening.

Questions about this item

What does the 90-degree dual-rotary design do once the fitting is installed in a loop?

The 90-degree angle routes tubing at a right angle while both ends rotate independently, letting you align the compression collar and the G1/4" thread without twisting the soft tube.

What thread standard does the fitting use and what does it connect to?

It uses a G1/4" thread with a 5 mm thread length, connecting directly to water-blocks, radiators or reservoirs that have matching G1/4" ports.

What tubing dimensions and clearance does the fitting need to fit and seal?

It accepts soft tubing with a 3/8" inner diameter and 5/8" outer diameter; the hidden O-ring seats inside the compression collar so no extra external clearance is required beyond the fitting body.
