    Alligator DS-P - Double Seal Valve Stem Cap

    As an industry leader and expert in flow-thru cap technology, Alligator outperforms all other flow-thru caps on the market.  You can inflate, deflate, and apply an air-gauge directly thru the valve cap saving time during inflation and pressure checks. The caps seal like a high pressure cap, yet offer the convenience of an inflate-thru extension.

    There are many lower cost, lower quality inflate-thru valve caps on the market today. At first glance they may resemble the DS-P “Gator Caps”; however, for durability, performance, and resistance to contamination and corrosion, there is no substitute for the genuine German design and quality of the DS-P caps.

    Details of the DS-P Double Seal Cap
    • Seal is located away from the opening
    • Contamination does not have a direct path to the seal
    • Contamination is directed away from the airflow
    • Encased in a light-weight, temperature resistant polyamide-6 covering

    • Genuine German design and quality

    Valve stem extensions
    I refer to these as extensions instead of caps since any pressure on the end of these devices will allow air to bleed out. Also, they are threaded and you can add a conventional cap to them. I purchased them to extend the valve stems on a couple of bikes where the BMW provided stems are too short to be gripped by clamp on inflators. These extenders appear sturdily made and should work well for my intended application.
