Frequently Asked Questions
No. The 120211 E-Ring is designed specifically for select GH-series hydraulic sprayers such as the GH 130, 200, 230, and 300. Always verify compatibility with your sprayer’s parts manual before purchasing.
It may be reused if it remains in excellent condition with no distortion or corrosion. However, many technicians prefer replacing retaining rings during pump rebuilds to ensure maximum reliability.
Yes. The heat-treated spring or stainless-steel construction provides the strength and corrosion resistance required for high-pressure use. Non-OEM rings may not deliver the same durability or retention force.
