T-piece with inflation valve for filling air to 2 pcs. air struts, or for refilling the pressure tank (the latter most relevant for Tesla X and Tesla S facelift vehicles).
Comes in two sizes, for 4mm and 6mm air hose.
Pre-facelift Tesla S 2013-16 only has a 6mm pressure hose system. Most of these models have a permanently mounted inflation valve on the car for topping up the tank. So the area of use for the T-piece is mostly limited to filling of the air struts themselves. It can be a good way to get air in them, e.g. if the compressor is disabled, the struts have fallen down and you need to move/use the car. The easiest way is likely to attach the pressure hoses to the T-piece at the valve block. An external compressor is then connected directly to the intake Schrader valve on the T-piece. A simple battery-powered one can be used, but it must have some pressure capacity. Fill up the air struts until the pressure reaches 7-8 bar.
Tesla X and S facelift vehicles from 2016 have a 4mm air hose system, with one exception: the pressure hose from tank to compressor is 6mm. Few of these models have a fixed inflation valve. This means that if a tank top-up is desired, a 6mm size T-piece applies. After assembly, the T-piece is permanently installed on the car, so you can fill up with air (possibly nitrogen) if necessary. If, on the other hand, it is the air struts, let's say those at the front, that you want to refill, the 4mm T-piece size applies.
Hose cutter and a couple of strips for attaching the T-piece are included.

Just get in touch if you are unsure which one to choose. Also note, you can order a similar T-piece for refilling the pressure tank directly from Tesla. Part number is 1734432-00-A (price approx. NOK 540).
