Extremely high quality, tall Valve Stem Caps for full sealing of TPMS stems and most other standard valve stems. Our Premier Universal Design makes a great replacement for the OE caps, if yours are lost during a refill, they are a perfect match for your tire pressure monitor system caps. The black matched all rubber stems for a clean look and they will fit on most every car, truck, SUV, bicycle, motorcycle, trailer, etc, with schrader and other common valve stems.
The patented design creates a double watertight seal, no other cap can do this. The inner Red Silicone seal crates and O-ring that perfectly mates the top of the brass threads. The long extended sides have a unique inner taper that locks to the top of the rubber stem, to create an interference wedge fit that holds cap tight so it won't vibrate loose or allow water to seep in. Even when the caps are submerged in water or mud, zero liquid is allowed into the area where the critical schrader pressure valve is mounted.
