Description
    Parker PGI’s Vented Cap Body Wellhead Grease Fittings feature the Positive Flow Ball Support. This design directs the flow of the lubricant and/or sealant through the center of the spring without passing through the spring coil, reducing the tendency to “pack-off.” The Positive Flow Ball Support is available in many other fitting styles.

    Another feature of the Vented Cap Body Wellhead Grease Fittings is the heavy-duty radial rivet crimp. This special crimp provides the best “blow-out” protection of any available crimped style fitting. The radial rivet crimp process conforms to the latest revision of NACE when manufactured with 316 SS or 4140 body material.

    The Free Flow fitting style utilizes a unique spring retainer that is threaded into the body of the fitting. This special retainer also acts as a ball support and spring guide, and its design allows for the Free Flow of lubricants and sealant around the spring, instead of through it.
