Overview

The Promata Stem8 Valve Adapter (T-Valve) is an innovative, cost-effective accessory designed specifically for vehicles equipped with external TPMS sensors. Standard external sensors occupy the tire valve, forcing users to remove the sensor every time they need to inflate the tire. Developing new molds for built-in TPMS is extremely expensive. The Promata T-Valve provides a brilliant solution: it creates a dedicated secondary inflation port, allowing you to inflate tires directly without ever removing the TPMS sensor.

Why Choose Promata T-Valve?

The Hidden Cost of External TPMS

• Blocked Valve: External sensors screw directly onto the valve stem, making standard inflation chucks difficult to connect.

• Time-Consuming: Users must constantly unscrew and reinstall the sensor for routine inflation or pressure checks.

• High Mold Costs: The alternative (designing a new internal TPMS) requires massive investment in new tooling and molds.

• Sensor Damage Risk: Frequent removal increases the risk of thread damage or sensor malfunction.

The Perfect Solution

The Problem	The Promata Solution
Sensor blocks the valve stem	T-Valve design with a dedicated inflate port
Tedious to remove sensor for air	Inflate directly without removing the sensor
New internal TPMS molds are too expensive	Cost-effective upgrade using your existing sensors

 

 

Key Product Advantages from Promata

• No-Disassembly Inflation: The T-junction design allows you to connect your air chuck to the dedicated inflate port while the TPMS sensor remains installed on the side port.

• Cost-Effective Alternative: Avoid the huge expenses of developing new molds for internal TPMS systems. Maximize the value of your existing external sensors.

• PremiumStainless Steel: Built with heavy-duty stainless steel for maximum durability, anti-corrosion, and superior sealing performance.

• Easy Installation: Screws directly onto the existing tire valve. The sensor then mounts onto the T-Valve.
