Our Products

  • R - Series Gaskets R - Series Gaskets

    These gaskets are used in pressures up to 5,000 PSI in API 6B flanges, and up to 2,500 PSI in ASME/ANSI B16.5 flanges. The oval type is the only gasket that fits a round bottom groove.

  • RX - Series Gaskets RX - Series Gaskets

    RX gaskets are designed for pressures up to 5,000 PSI in API 6B flanges. They are interchangeable with R-oval or R-octagonal rings used on API 6B flanges.

  • BX - Series Gaskets BX - Series Gaskets

    The BX Series can only be used with 6BX flanges and 16BX hubs. BX Gaskets are designed for higher-pressure ratings starting at 5,000 PSI and ending with 20,000 PSI.

  • Subsea Series Gaskets Subsea Series Gaskets

    SRX and SBX series are API standardized subsea gaskets. RX and SRX or the BX and SBX will fit into their appropriate flange designated numbers.

  • Rubber Coated Gaskets Rubber Coated Gaskets

    Rubber coated gaskets start with a precision machined low carbon steel gasket. We then add rubber that is molded to the gasket in an electrically induced 300 ton press.

  • Combination RTJ Gaskets Combination RTJ Gaskets

    Combination RTJ gaskets are a combination of two different API ring joint gaskets, and are used to connect flanges with the same bolt circle dimensions and number of bolt holes

  • Split Gaskets Split Gaskets

    Split gaskets are used in applications where an API flange is mated up to ANSI flange, where typically a low pressure spiral wound gasket would be used.

  • Valve and Wellhead Gaskets Valve and Wellhead Gaskets

    Valve, wellhead and subsea gaskets can be manufactured in any material and coating combination. We can reverse engineer used gaskets to ensure obsolete or otherwise unidentified connections have a proper seal.
