    Pipe Thread Protector Caps

    Biaohuang offers a wide range of caps to cushion fragile threads during transport and storage. Available in a variety of materials, colors and styles, from rig ready to our patented pull tab design for quick and easy removal in the field. Our economical components ensure your pipes reach your customers undamaged.

    Variety of styles.

    Round Vinyl Caps
    Vinyl caps are ideal for use as pipe thread protectors. The flexible vinyl material extends over the threads to provide a tight seal that not only protects the threads, but also prevents contaminants from entering the pipe or tubing. The flexible vinyl cushions the threads from damage and will not crack or shred like many hard plastic caps. Vinyl caps are available in short and long versions.
    Vinyl Label Caps
    These caps offer the same benefits as the round vinyl caps with the added benefit of an EZ remove label.
    Threaded Caps
    For applications requiring thread protection and positive low pressure sealing, BiaoHuang offers plastic threaded caps in standard thread sizes from 3/8-24 to 1-1/16 - 12.
    Polyethylene Caps
    These low cost caps are ideal for high volume applications and are available in a wide range of sizes.
    For internal pipe thread protectors, StockCap offers flexible vinyl plus plugs, tapered T-plugs and polyethylene threaded plugs.
