Review on Muzzys (Pack of Four) Double Seal Flow Through Valve Stem Tire Caps π for High Pressure Truck Car RV Semi Bus Tires - INFLATE and Check Pressure Effortlessly! by Kyle Fachini
More effort to seal, but the fluidity is good.
I've tried a few air liners on these valve extenders and both took a bit of effort to ensure a good seal, but the airflow was significantly better than the longer Slime brands.
Pros
- Beautifully Packaged
Cons
- Lots
