The valve stems we sell are compatible with TPMS sensors (hence the labeling) but do not require sensors to install in the wheels. When using the metal valve stems without sensors, you will basically torque them down until you hear the crush washer "set". I will try to find some visuals and/or a better explanation for the install and post them later today, as we have seen this question come up a couple of times before.
The torque setting in which the crush washer sets should be 4 nm or 35 in/lbs. You can use a torque wrench to reach this without risking any damage to the wheel or stem.
