Replacement riser seal engineered for Hunter I-25 rotor pop-up assemblies. Designed to restore a watertight seal between the riser and body cup, this direct-fit part stops leaking risers, reduces water waste, and extends rotor service life. Fits: Designed for Hunter I-25 series rotors (SKU 221200 / I2504-06). Confirm model compatibility before ordering. Components: Two-piece assembly (hard plastic seat plus soft rubber seal) replaces worn sealing surfaces for reliable operation. Dimensions & color: Grey replacement seal; manufacturer-listed dimensions approx 4.5 × 4.5 × 0.01 cm and a lightweight form factor for easy handling. Performance: Restores pop-up seal integrity to prevent leaks between the riser and body under normal operating conditions. Installation: Field-replaceable without special tools - remove the inner assembly, fit the hard plastic seat with channel facing down, install the soft rubber seal, then reseat the cap and spring. Note: Intended for Hunter rotors; will not fit unrelated brands or non-compatible models. If unsure, match your rotor model number before purchasing. Keep a spare riser seal on hand as part of routine maintenance to minimize downtime. This genuine-style replacement helps maintain system efficiency and reduces the need for more extensive repairs. For questions about fit or installation, reference the Hunter I-25 product documentation or contact technical support with your rotor model and serial information. Show more
