Keep your tires – and your travels – safe with these TST 507 Flow-Thru Sensors. Designed specifically for metal valve stems, these sensors let you monitor tire pressure and temperature in real time. The cool 'flow-thru' design means you can add air to your tires without removing the sensor – super convenient! They pair easily with your existing TST 507 monitor (monitor sold separately) and each sensor shows up uniquely on the display, so you know exactly which tire needs attention. You can even set custom high/low pressure and temperature alerts for each axle. The TST 507 system can monitor up to 110 tires across multiple vehicles or trailers, making it perfect for RVs, motorhomes, 5th wheels, boat trailers, and more. Installation is a breeze: just screw them onto your tires and pair them with your monitor. Backed by a three-year warranty and a 30-day return policy, plus great customer support. Don't hit the road without knowing your tires are in good shape. Safety first, always!
