Fit the target sprayer and reasonably easy to install. Stopped piston leak, which was needed. Being more careful to clean sprayer and leave a detergent residue for protection, and lubricate a bit more often as well. Plan to partially rotate parts annually to spread long-term gasket and ring wear due to slight eccentricity of piston assembly when operated. Seems to be a normal condition for manually operated sprayers. Not sure about motor units. ## Features - Replace: 0062115 0062991 0062139 0062140 O-Rings; 2* 4074350 Sealing Plugs; 2* 0070260 Compression Springs & 4400189 Viton Collar - Replace: 4061257 Valve Plate, fit for Solo 425 425 435 473P Replace 6339964 4061257 - Materials: Made of high quality materials, simplity to replacement - Note: Please make sure the car's model if fit your car or not before you order ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #148,418 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #50 in Faucet O-Rings | | Customer Reviews | 4.3 out of 5 stars 112 Reviews | ## Product Details - **Material:** Viton - **Brand:** Shunevade - **Color:** Black - **Manufacturer:** Shunevade - **Unit Count:** 1.0 Count ## Images ![Piston Sprayer Pump Repair Seals O-Rings for Solo 425 435 Replace 6339964 - Image 1](https://m.media-amazon.com/images/I/61XDRGv9RhL.jpg) ![Piston Sprayer Pump Repair Seals O-Rings for Solo 425 435 Replace 6339964 - Image 2](https://m.media-amazon.com/images/I/612koaObA3L.jpg) ![Piston Sprayer Pump Repair Seals O-Rings for Solo 425 435 Replace 6339964 - Image 3](https://m.media-amazon.com/images/I/61es6G57c9L.jpg) ![Piston Sprayer Pump Repair Seals O-Rings for Solo 425 435 Replace 6339964 - Image 4](https://m.media-amazon.com/images/I/51ks5Vh1GcL.jpg) ![Piston Sprayer Pump Repair Seals O-Rings for Solo 425 435 Replace 6339964 - Image 5](https://m.media-amazon.com/images/I/612g+J99G2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value and all needed parts were sent *by J***. on July 27, 2026* Good value and quick delivery ### ⭐⭐⭐⭐⭐ Solved leak issue *by N***R on March 20, 2024* Received on time, well packaged, as advertised.
