TPMS Sensor Installation Kit 4 Pieces Valve Stems Screws Tire Pressure Sensor

Installing TPMS sensors goes wrong in the same four places every time: the valve is reused and leaks, the nut is overtightened and cracks the stem, the sensor is fitted without a new seal, or the relearn is skipped and the light comes back. This kit is built around those failure points. It supplies four programmable sensors, four rubber snap-in valve stems, four fixing screws and the seals, packed as a workshop set, so a fitter has everything for a full vehicle in one box instead of four separate line items. The sensors are sealed to IP67, rated to 900kPa and quoted at a 5-7 year battery life, and each unit is leak tested before packing.

• Deflate the tyre completely, break the bead and support the wheel before removing the old sensor.
• Fit a new rubber stem rather than reusing the old one, because the stem shoulder is the most common source of a slow leak.
• Tighten the fixing screw to 1.5Nm only; overtightening deforms the housing and can crack the stem base.
• Program the sensor to the vehicle protocol before fitting, so the relearn only needs a trigger, not a rewrite.
• Inflate to the door placard pressure, then complete the relearn and drive 5-10 minutes above 25km/h.

Q: Do I need a programming tool to install these sensors?
A: Yes, because the sensors are universal and must be written to the vehicle protocol before fitting. If your workshop has no TPMS tool, order pre-programmed OE replacements instead and skip this step.

Q: Can the old valve stem be reused to save time?
A: Not recommended. A rubber stem that has been in service for years has already taken a set, and refitting it is the most common reason a repaired wheel leaks within weeks. The kit includes new stems for that reason.

Q: Will four sensors cover any car?
A: Four covers a standard passenger car or light truck. For vehicles with a fifth spare wheel sensor, order one extra piece, which we supply separately.

Q: What are the MOQ and lead time?
A: MOQ is 20 sets, priced per set. Stock ships in 5-7 working days, and branded packaging is available from 200 sets.

Installation is where a good sensor earns its reputation or loses it. A kit that includes the stems, screws and seals removes the three shortcuts that cause comebacks, and the dual frequency sensor covers whatever comes into the bay next.
