Parker PGI's Giant Button Head 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 these 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.
