Details
The Barrow TB2D-02 is a G1/4" male to G1/4" male extender, the standard length of Barrow's dual male connectors. It joins two female G1/4" ports or fittings directly, for example a reservoir to a pump top, or it turns a female port into a male one. It is finished in shiny silver.

Join two female ports
Both ends carry a G1/4" male thread, so the TB2D-02 screws into two female G1/4" ports or fittings and connects them without tubing. Typical uses are a reservoir screwed straight onto a pump top, two blocks or radiators joined port to port, or a female fitting that needs to become male.
Sealed on both sides
Each end has its own O-ring that seals against the port face, so both connections are sealed when the extender is tightened.
H59 brass with a double-protected finish
Barrow says it uses high-quality H59 brass for the body and protects the surface with a double electroplating process, which it says gives a fine texture that is solid and durable.
Non-slip diamond knurling
The body between the threads has a diamond knurl. Barrow says it gives a sure grip when you screw the extender in by hand.
Two lengths
Barrow makes this dual male connector in two lengths: this standard TB2D-02 with a 10 mm body (20 mm overall) and the TB2D-MINI01 with a 5 mm body (15 mm overall) for the tightest spaces.
