TPMS 20008/20018 Tire Pressure Sensor Rubber Valve Stem - 100pcs pack

In this review the focus is on a package of snap-in style valve stems sold as replacement parts for TPMS sensor assemblies. The bottom line: this kit is for DIYers and fleet owners who already have compatible sensors and need reliable rubber valve stems and mounting hardware rather than complete sensors. It stands out because it includes valve cores, caps and mounting screws in a large 100pcs quantity, offering clear value for routine maintenance and multi-vehicle use while remaining straightforward to install.

Key Features

• Part Compatibility: Includes parts labeled 17-20008/20008/20018 so buyers can match these stems with compatible GM-style sensor housings.
• Material Construction: Made from rubber and pure copper components to provide a durable seal and good electrical contact where needed.
• Complete Snap-in Kit: Each stem ships with an installed valve core, a cap and a mounting screw so installers have the basic hardware needed for sensor attachment.
• Large Quantity: The package includes 100 pieces overall (sold as two 50pcs packs), which reduces repeat purchases for workshops and larger maintenance jobs.
• Easy Installation: Snap-in design and supplied screws make replacement quick for technicians familiar with TPMS assemblies.

Who It's For

This kit is best for vehicle owners, mechanics, and fleet managers working on Buick, Cadillac, Chevrolet, Dodge, GMC, Jeep, Pontiac, Saturn, and Subaru vehicles who already have the TPMS sensors and only need replacement valve stems and mounting hardware. It is particularly suited to routine tire service where multiple stems are replaced at once.

If someone needs complete tire pressure sensors with electronics, they should look elsewhere because this product does not include the sensor module itself. Also, those who prefer preassembled OEM valve/sensor combos should choose a full sensor replacement rather than these snap-in stems.

Pros & Cons

Pros

• Good value for money when replacing stems in multiple tires due to the 100pcs quantity.

• Simple snap-in design with installed valve cores speeds up installation for experienced technicians.

Cons

• Not a complete TPMS sensor; buyers must already have compatible sensor housings to use these stems.
• No instruction manual included, so first-time installers may need guidance or professional help.
