Plastic Dust Cap
The Plastic Dust Caps are the small covers employed on the valve trunk of a bicycle or car tire to stop dust or other small elements from entering the valve as well as damaging it. The caps also make a pressure seal, assisting to prevent devaluation of the tire due to slight gas leakage past the tire regulator. These are designed to shield the Schrader valve, a valve trunk into which the valve stem core is threaded. These can keep the moisture as well as dirt out. These closures are hard-wearing, serviceable and highly functional. The Plastic Dust Caps are really very robust and extensively versatile.
