QSP AN T-Pieces, Y-Pieces, Reducers

QSP’s T-pieces, Y-pieces and reducers are the junctions of a fluid system: they split one line, join lines together, or change size between parts. The range is organised by what the junction connects to. Aluminium T-pieces take AN fittings from AN3 to AN16, in plain, bulkhead and swivel forms, and a rotatable T adapter lets the branch point in any direction. Coupler T-pieces have female NPT threads from 1/4 to 1 in. Oil T-pieces with an M12 x 1.5 or 1/8 NPT male end let a gauge sender share a port with an existing switch.

For plain hose there are plastic (POM) T- and Y-pieces from 6 to 25 mm, plus brass versions, and a stainless steel AN3 T-piece suits brake lines. Expanders step from one AN size to a larger one, such as AN6 to AN10.

Choose aluminium for fuel and oil lines built with AN hose, plastic for vacuum, breather and low-pressure coolant lines, and stainless steel where the line carries brake fluid. The colour follows the material: blue or black aluminium, white plastic and gold-coloured brass.
