Common Applications

The B-HTJ-L14-RD90 combines a 360-degree rotary G1/4 male adapter and a hard-tube compression collar in a single body, so a 90-degree turn can be made directly from a port without stacking a separate elbow on top of a compression fitting. The compression end accepts 14mm outside diameter rigid tubing in PETG, acrylic, or metal. The rotary half lets the tube be aimed in any direction after assembly, which reduces the number of straight runs and bends required in a clean rigid build. Each fitting is supplied with pre-installed O-rings on both the thread and the tube seat. Use only in copper, brass, and nickel loops with a non-aluminum coolant; this fitting is not intended for aluminum-radiator systems or for PrimoChill Opaque and VUE coolants.

Frequently Asked Questions

Q: What thread and tube size does this fitting use?

A: G1/4 male thread on the rotary side and a compression collar sized for 14mm outside diameter rigid tubing.

Q: Can I use this fitting in an aluminum loop?

A: No. Like other Bykski brass fittings, it is intended for copper, brass, and nickel loops only; mixing aluminum and copper components causes galvanic corrosion.

Q: Is it compatible with PrimoChill Opaque or VUE coolants?

A: No. Bykski lists this fitting as not compatible with PrimoChill Opaque and VUE coolant series. Use clear or dyed coolants designed for copper-loop hardware.

Q: What is in the box?

A: One B-HTJ-L14-RD90 fitting with O-rings pre-installed. Tubing and the matching G1/4 port are not included.

Q: What colors are available?

A: Production runs include Silver, Gold, Blue, Grey, and Black finish options (V2 revision); availability depends on the retailer.
