AN Male with AN Female On-The-Run T-Pieces

Add a branch connection to a compatible AN fluid line with our AN Male with AN Female On-The-Run T-Pieces. The straight-through run combines a swivel female AN connection with a male AN connection, while a second male AN connection forms the branch.

Why Choose Our On-The-Run T-Pieces?

Swivel Female Connection On-The-Run

The female AN connection sits on the straight-through run and swivels to help align the connected fitting or hose during installation.
AN Male Branch Connection

A male AN connection forms the branch of the T-piece, providing an additional connection point from the main fluid line.
JIC 37° Flare Connections

The AN connections use JIC 37° flare sealing surfaces for use with compatible mating AN fittings and hose ends.
6061-T6 Aluminium Construction

Manufactured from 6061-T6 aluminium for a lightweight, high-strength construction.
Black Anodised Finish

The black anodised finish provides additional protection against wear and corrosion.

What Is an On-The-Run T-Piece?

An on-the-run T-piece is a three-way adapter where the female connection forms part of the straight-through main run rather than the branch. On this design, the main run has one swivel female AN connection and one male AN connection, with a second male AN connection forming the branch.

Compact Three-Way Fluid Connection

This arrangement provides a compact way to introduce an additional branch into compatible fuel, oil, coolant and other fluid systems while retaining useful alignment at the swivel female connection.

Frequently Asked Questions

What is an AN male with AN female on-the-run T-piece used for?
It provides a three-way connection within a compatible AN fluid system. The female connection sits on the straight-through run, while one of the male connections forms the branch.
How are the connections arranged?
The straight-through run has one swivel female AN connection and one male AN connection. A second male AN connection forms the branch of the T-piece.
Does the female connection swivel?
Yes. The female AN connection on the straight-through run swivels to help align the connected fitting or hose during installation.
Are all three connections the same size?
Yes. All three connections on each T-piece use the same AN size. See the available options for the exact size and thread.
How do the AN connections seal?
The AN connections use JIC 37° flare sealing surfaces. The fluid seal is created between the mating flare surfaces rather than by the threads.
Do the AN threads require thread sealant?
No. The connections seal at the mating 37° flare, so thread sealant should not be used to create the fluid seal.
What is the T-piece made from?
It is manufactured from 6061-T6 aluminium with a black anodised finish for a lightweight, high-strength construction with additional protection against wear and corrosion.
