Fitting for 3/8" ID Soft Tubing

The Bitspower BP-MB90R2LCPF-CC3U is a G1/4" compression fitting made from high-quality brass with a matte black finish. It accepts soft tubing measuring 3/8" inner diameter and 5/8" outer diameter. A hidden O-ring design ensures a secure seal inside water-cooling loops. The 90 degree dual rotary mechanism allows flexible routing without stressing connected components.

Suits Custom Loops with 3/8" ID Tubing

This fitting matches builders assembling custom liquid cooling using 3/8" ID and 5/8" OD soft tubing on G1/4" threaded ports. The rotary function helps align tubing runs in tight spaces where rigid bends are impractical. Buyers using hard tubing, different tubing diameters, or non-G1/4" thread standards should look at alternative fitting types. It is not intended for push-on connections or barb-style installations.

90 Degree Dual Rotary Elbow

The defining specification is the 90 degree dual rotary elbow geometry combined with G1/4" threading for 3/8" ID, 5/8" OD soft tubing. This angle and rotation capability determine whether the part fits the planned tube path and port orientation. Verify tubing dimensions and port thread type against these parameters before purchase. The hidden O-ring and brass construction support reliable sealing in standard custom loops.

Questions about this item

What tubing inner and outer diameters does this 90 degree dual rotary compression fitting accept?

This fitting is designed for soft tubing with a 3/8 inch inner diameter and a 5/8 inch outer diameter.

How do I install this G1/4 inch threaded fitting and what step is often missed?

Screw the G1/4 inch thread with its 5mm length into the component, then push the tubing fully over the barb until it seats against the hidden O-ring; the common error is not inserting the tube far enough to engage the seal.

Which parts of this matte black brass fitting may need replacement after extended use?

The hidden O-ring inside the compression body is the primary wear item and should be replaced if a leak develops or during loop maintenance.
