Simpson Pressure Washer Seal Kit (16pcs)

This **AIYOYOLIFE pressure washer pump seal kit** is a direct replacement for Simpson Cleaning models, including the **8.7GA12, 9.6GA12, 530001, 530002, 530008, 530009, 530016, 530028, 530030, 90036, 90037, 53BRD23, and 53BRD25** (part number **7105742**). Designed for high-performance pressure washers, the kit features **low and high-pressure O-rings** crafted from composite elastic materials reinforced with fibres, ensuring exceptional resistance to pressure, wear, and chemical erosion. This durability allows the seals to withstand frequent start-stop cycles and extreme pressure without deforming, even after prolonged use.

The kit resolves common issues caused by seal aging, such as **water leakage, unstable pressure, abnormal noise, and reduced power output**. By reducing friction between the piston and cylinder block, it minimises wear on critical components and prevents rusting of the pump body due to leaks. The included **13-piece set** covers all essential seals: **3 high-pressure water seals, 3 low-pressure water seals, 3 rubber seal retaining O-rings, 3 fibre washers, 1 oil seal hook, and 1 pack of lubricant**—everything needed for a complete repair. Whether maintaining professional equipment or restoring a home pressure washer, this kit ensures reliable, long-term performance.

**Note:** Always follow manufacturer guidelines when replacing seals to maintain warranty validity and ensure proper installation.
