Common Applications

The Fm-90DX is a G1/4 male-to-female 90-degree adapter machined from brass, with a single rotary joint that turns continuously through 360 degrees and seals against an internal O-ring. It steps a tubing run cleanly around a corner without forcing a hardline bend, which is useful between a radiator outlet and a CPU block inlet or between a distribution plate and a reservoir port. The fitting is offered in black or silver finishes that match common Barrow, Bykski, and FormulaMod fitting families. Hand-tight installation is sufficient; over-torquing can cut the O-ring.

Frequently Asked Questions

Q: What thread standard does the Fm-90DX use?

A: G1/4 male on the static side, G1/4 female on the rotating side.

Q: Is the rotation continuous?

A: Yes, the joint rotates a full 360 degrees and stays sealed throughout.

Q: What material is the fitting?

A: Brass body with a plated finish in black or silver.

Q: Should I use thread sealant or tape?

A: No. The fitting uses an O-ring seal and only needs to be hand-tight; sealant or tape can damage the O-ring.

Q: Is it compatible with aluminum loops?

A: No, the brass body should not be mixed with an aluminum-only loop because of galvanic corrosion.
